I just switch to try develop on Linux for a while.
But one thing I couldn't understand how to solve it, as I mentioned in topic.
I'm going to develop a project that need Java SDK, then I installed the SDK with command:
#bash
sudo apt install openjdk-17-jdk-headless
After installation finished, I could run command java -version and javac -version to see the result of installation and it looks OK.
openjdk version "17.0.3" 2022-04-19
OpenJDK Runtime Environment (build 17.0.3+7-Ubuntu-0ubuntu0.22.04.1)
OpenJDK 64-Bit Server VM (build 17.0.3+7-Ubuntu-0ubuntu0.22.04.1, mixed mode, sharing)
And then when I open IDE (Intellij IDEA) and it has feature of integrated terminal. (see picture)
But when I try to test java -version it was shown the error:
bash: java: command not found
As you can see from picture, I run java -version on terminal it return output properly, but when I run the same command java -version, it output with error message, like it couldn't find the java SDK that I installed.
Could anyone help me to describe the reason and solutions to solve the issue?
P.S. This is same on VS Codium.
I found the answer.
Solution:
Install the IDE app with the file from official website instead of using package manager of OS.
Description:
The cause is I installed the IDE via Package Manager of OS (here I'm using Pop_OS, install via Pop!_Shop)
And its package manager has some strict rules for security purpose.
I'm not sure, Pop_OS using which package manager, but I'll raise Flatpak as reference: https://docs.flatpak.org/en/latest/sandbox-permissions.html
And on blacklisted directories, my installed java command is under /usr/bin/ which is in blacklist.
I have a problem with latest version of Cytoscape 3.8.0 It doesnt start. I can see only logo and than nothing. Computer is running OSX 10.13.6. I am using successfully version Cytoscape 3.7.2 but I want to upgrade. When I run script mac.sh I got following:
Target Cytoscape version: 3.8.0
Your shell is bash
Compatible OS version found: 10.13
Pass: OS Version = 10.13.6
Pass: Following Oracle JDK found:
/Library/Java/JavaVirtualMachines/jdk-11.0.7.jdk
Fail: Java is not reachable.
Try re-installing Java 11.
I can confirm that java is in place /Library/Java/JavaVirtualMachines and versions jdk-11.0.7.jdk jdk-12.0.2.jdk jdk-14.0.1.jdk
I guess that version 37 and 38 work with java 11? I have reinstalled java 11 with same results as before. Version 38 doesnt start. When I try to start version 38 from terminal with cytoscape.sh I got long error message which starts with:
Unable to find any JVMs matching version "1.8".
karaf.base: /Applications/Cytoscape_v3.8.0/framework
JAVA_HOME: null
ERROR: Error parsing system bundle export statement: org.osgi.dto;version="1.0",org.osgi.resource;version="1.0",org.osgi.resource.dto;version="1.0...
I can paste whole error message if needed.
Any idea what should i do? Thanx.
Cytoscape 3.7.x requires Java 8. Cytoscape 3.8.0 requires Java 11. It looks like your java home is incorrect. If you do:
/usr/libexec/java_home
it should point to your java 11 installation. On my mac it says:
/Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home
Note that the "/Contents/Home" is important. To set your actual JAVA_HOME, do
export JAVA_HOME=`/usr/libexec/java_home -v 11`
I had this same problem. What Scooter Morris mentioned is correct, but I had to follow an additional link on stack overflow to get it fixed.
This is exactly what I did:
In my case I had to run:/usr/libexec/java_home -V to see the Java Virtual Machines I have installed and specify the V 11 using:
export JAVA_HOME=`/usr/libexec/java_home -v 11.0.7`
Then running the ./mac.sh command tells me everything checks out and Cytoscape can finnaly run :)
Edit: I should add that I can only run cytoscape by launching it from the terminal via:
cd /Applications/Cytoscape_v3.8.0
./cytoscape.sh
Clicking the app icon only results in the app crashing on load but it appears to work fine by launching it from the script. I don't have this issue on Mac OS 10.14 so maybe its a software version issue or some background app in my computer is getting in the way of launching the app normally.
I have created a linear programming model in Python and want to solve this with the CPLEX solver on MacOS High Sierra. If I keep the problem small, the solver works just fine, if I increase the size of the problem I get the following message:
CPLEX Error 1016: Promotional version
I've downloaded the Student version to surpass this limitation of the free version of CPLEX Studio and got the .bin file:
cplex_studio129.linux-x86-64.bin
If I try to install it in my terminal, I get the following message:

I've tried to use LAX_VM /Library/Java, reinstalled Java as well, but without succes. Can anyone help me out?
You downloaded a Linux version (linux-x86-64) of CPLEX, instead of the version for macOS.
I Finally got it working, thanks for the input #xavier-nodet! Here is my solution for others with the same problem:
I installed the academic version of CPLEX with the following command as described in the instructions:
python setup.py install --home /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages
However, the files are placed in the following dir:
/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/lib/python/
I manually moved the cplex and docplex folders to the site-packages directory, thats it!
I'm getting this error when I try and install node on my new mac
error: could not configure a cxx compiler!
The error always occurs when I get to the ./configure part of the installation
I found this problem which applies to a linux build with the same error, but the solution does not seem to apply in my case:
How to compile/install node.js(could not configure a cxx compiler!) (Ubuntu).
I also took a look at the troubleshoot guide on the node wiki here:
https://github.com/joyent/node/wiki/Troubleshooting-Installation
and tried this solution:
export PATH=/Developer/usr/bin:$PATH
ISYSROOT="-isysroot /Developer/SDKs/MacOSX10.5.sdk"
export LINKFLAGS=$ISYSROOT CXXFLAGS=$ISYSROOT CFLAGS=$ISYSROOT
./configure --prefix=$HOME --without-ssl
make
But I get the same problem when I get to the ./configure step
Any advice, insights or help would be much appreciated here.
Thanks
When you install Mac OS X Developer Tools (XCode, etc) ensure you have the Unix Tools option checked. I had to remember to install Developer Tools/Unix tools when I set up my new MBP and it resolved this error for me.
Optionally, you could remove and try installing with Homebrew. However, it still has the same requirements (XCode/Dev Tools) so ensure that you have those installed.
Hope this helps.
I had this problem too, I resolved this in a different way, as far as I know xcode 4.3.1 doesnt come with an Install Xcode.app file from the appstore, if you are under this case, just run xcode, go to preferences -> downloads and click on the Install button for the command line tools option. I did just that and all the errors on the .configure and make commands were gone :)
I had the same problem on OSX 10.7 with Xcode 4.2. I was trying to build node v0.4.7. I kept getting "unable to configure a c compiler" error. What finally worked for me is installing the GCC compiler seperately. I found a nice package for that here:
https://github.com/kennethreitz/osx-gcc-installer/
configure is currently broken for some versions of MacOS; for more details, see How to compile Node.js v0.4.2 on MacOS 10.5.8. The working approach cited there is as follows:
export PATH=/Developer/usr/bin:$PATH
ISYSROOT="-isysroot /Developer/SDKs/MacOSX10.5.sdk"
export LINKFLAGS=$ISYSROOT CXXFLAGS=$ISYSROOT CFLAGS=$ISYSROOT
./configure --prefix=$HOME --without-ssl
make
This worked for me .

After installing XCode 4.3.2 (in Mac OS X Lion) I still had the error.
Open XCode, Preferences, Downloads and installed Command Line Tools.
After it gets installed ./configure runs ok.
I would like to use the WatchService API as mentioned in this link:
http://download.oracle.com/javase/tutorial/essential/io/notification.html
After reading around, I found out that WatchService is part of the NIO class which is scheduled for JDK 7. So, it is in beta form. It's fine.
http://jdk7.java.net/download.html has the JDK which I downloaded and extracted. I got a bunch of folders. I don't know what to do with them.
Then, I read around some more and found that some nice group of people created JDK 7 as a binary so someone like me can install it easily. It is called Open JDK:
http://code.google.com/p/openjdk-osx-build/
So, I downloaded the .dmg file and install it. Then I open "Java Preference" and see that OpenJDK7 is available.
So, now I feel that I can start trying out WatchService API. From the tutorial in the first link, the author gave a .java file to test it out first and make sure that it is running. Here is the link to the file:
http://download.oracle.com/javase/tutorial/essential/io/examples/WatchDir.java
So, I boot up Eclipse (actually I use STS) and create a new Java project and choose JaveSE-1.7 in the "use an execution environment JRE:". Under the src folder, I copy pasted the WatchDir.java file.
And I still see tons of squiggly red lines. All the "import.java.nio.*" are all red and I cannot run it as a Java app.
What do I need to do?
This is how I got 1.7 to work with Eclipse. I hope it helps.
I Downloaded the latest OpenJDK 1.7 universal (32/64 bits) JDK
from Mac OS/X branch from http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
copied the jdk to /Library/Java/JavaVirtualMachines/ next to the
default 1.6.0 one
In Eclipse > Preferences > Java > Installed JREs you add a new one, of type MacOS X VM, and set the home as /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home and
name Java SE 7 (OpenJDK)
Click Finish
Set the added JRE as default
that should be it :)
Oracle has released JDK 7 for OS X.
Java 9, 10, 11
Years ago, Apple joined the OpenJDK project, transferring their formerly proprietary macOS-specific JVM code as free-of-cost open-source. Apple ceased distribution of their own branded JVM/JDK, relying on Oracle’s branded releases to include a version for macOS.
Oracle has recently announced their intention to bring their Oracle-branded JVM release to feature parity with the OpenJDK project, with virtually the same code base. The company even donated their previously commercial tools, Flight Recorder & Mission Control, to the OpenJDK project. This is part of the shift to a new rapid “release train” plan for predictably scheduled versioning of Java and OpenJDK. Notably, the periods for free-of-cost public updates is now shortened. See this 2017-09 announcement and this posting by Mark Reinhold.
As a result of all this, macOS users of Java have a choice of vendors for a Java implementation. At this point, at least three sources are based on OpenJDK for macOS:
Oracle releases of the JDK and JRE, with optional paid support.
Azul Systems releasing:
Zulu line of free-of-cost JVMs with optional paid support.
Zing line of commercial JVMs with special features such as an alternate garbage-collector.
OpenJDK source code, roll-your-own compilation & installation (perhaps not practical for most of us).
Meanwhile, IBM donated code for a JVM to the Eclipse Foundation, now housed in the OpenJ9 project. I wonder if they might support a macOS release as well, though it is too soon to tell.
Personally, I am currently using the Zulu release of Java 10.0.1 from Azul on macOS High Sierra successfully with IntelliJ 2018.2 to produce Java-backed web apps with Vaadin.
Installation/Removal
Both Oracle and Azul provide utterly easy-to-use installers to install the JVM/JDK on your Mac. Verify your installation by using the Terminal.app (or equivalent) to type and run:
java -version
You will find the Java installations in this folder at the root level of your drive (not in your home folder):
/Library/Java/JavaVirtualMachines
Each version from each vendor is found there, in a labeled nested folder. You can delete any installation simply by deleting the nested folder for that version and providing your system password when prompted.
Java 8
You can download the Java Development Kit (JDK) for Java 8 for the supported versions of Mac OS X:
Mountain Lion (10.8.3+)
Mavericks (10.9)
Yosemite (10.10)
El Capitan (10.11)
Each version of JVM you install can be found here:
/Library/Java/JavaVirtualMachines
For more instructions and FAQ, see this Oracle Guide.
Java 7
For every release of Java 7 since Update 4, a Mac version has been ready alongside the other platforms. Runs on Macs with 64-bit hardware on Lion (10.7.3+), Mountain Lion (10.8.3+), and Mavericks (10.9.x).
Oracle announced the official release of the JDK for Java SE 7 Update 4 on Mac OS X (Lion), as of 2012-04-26. No more need for the tricks discussed on this page.
Installation is simple per these instructions:
Download from the usual place on the Oracle web site.
Mount the DMG.
Run the installer.
This release has a few limitations, most notably the lack of support for Java Web Start and the Java Plugin for web browsers. That support is expected later this year.
After installing, read the JDK for Mac ReadMe. Most importantly, if you want Java 7 to be the default, drag it to the top of the list in the Java Preferences app found in your Utilities folder.
Mac OS X easily supports multiple JVMs simultaneously. Each is now found here:
/Library/Java/JavaVirtualMachines
Congratulations to the Apple & Oracle teams for their achievement. This geek gets a thrill seeing Mac OS X listed as a "Certified System Configuration".
Tip: To start Eclipse on a Mac with only Java 7 installed, open the alias file named eclipse rather than the file named Eclipse.app.
Java 6
Apple continues to supply an up-to-date implementation of Java 6 for all versions of Mac OS X up through Mountain Lion.
If you do something that requires Java, such as type "java -version" in Terminal.app, a dialog appears offering to install Java for you. If you accept, installation happens automatically similar to other "Software Updates" from Apple.
You will find Java installed in this location, different than Java 7 & 8:
/System/Library/Java/JavaVirtualMachines
Java 6 has reached end-of-life with Oracle as of 2013-02 (unless you have a commercial support agreement with Oracle). So you should be moving to Java 7 or 8.
Testing New Version
In Terminal.app, type java -version to verify which version is the current default.
Deleting Old Versions
After installing a fresh version, you may want to visit the folder described above to delete old versions. Move the folder to the Trash, and provide your System password complete the move.
By the way, Apple provides a mailing list for developers’ technical issues related to Java on OS X.
An easy way to install Java 7 on a Mac is by using Homebrew, thanks to the Homebrew Cask plugin (which is now installed by default).
Run this command to install Java 7:
brew cask install caskroom/versions/java7
Get cask
brew tap caskroom/cask
Install java7:
brew tap caskroom/versions
brew cask install java7
(I had difficulty finding the download link of java7 on oracle website, as they're just "recommending" java8 )
EDIT January 2018 (As pointed by Ankur):
Use zulu7 cask. Zulu is a certified build of OpenJDK produced by Azul Systems that should be around for a long time (they even offer JDK6 builds still).
brew cask install caskroom/versions/zulu7
I know that some may want to smack me for re-opening old post, but if you feel so do it I just hope this may help someone else trying to set JDK 7 on Mac OS (using IntelliJ).
What I did to get this working on my machine is to:
followed instructions on Oracle JDK7 Mac OS X Port for general installation
in IntelliJ open/create new project so you can add new SDK (File > Project Structure)
select Platform Settings > SDKs, press "+" (plus) sign to add new SDK
select JSDK and navigate to /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home. Do not get it mistaken with /Users/YOUR_USERNAME/Library/Java/. This will link 4 JARs from "lib" directory (dt.jar, jconsole.jar, sa-jdi.jar and tools.jar)
you will need also add JARs from /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home/jre/lib (charsets.jar, jce.jar, JObjC.jar, jsse.jar, management-agent.jar, resources.jar and rt.jar)
after installing the 1.7jdk from oracle, i changed my bash scripts to add:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_13.jdk/Contents/Home
and then running java -version showed the right version.
It's possible that you still need to add the JDK into Eclipse (STS). Just because the JDK is on the system doesn't mean Eclipse knows where to find it.
Go to
Preferences > Java > Installed JREs
If there is not an entry for the 1.7 JDK, add it. You'll have to point Eclipse to where you installed your 1.7 JDK.
If Eclipse can't find a JRE that is 1.7 compatible, I'm guessing that it just uses your default JRE, and that's probably still pointing at Java 1.6, which would be causing your red squiggly lines.
I needed to adapt #abe312's answer since there has been some changes with brew lately.
I installed zulu7 and setup JAVA_HOME by running:
brew install --cask homebrew/cask-versions/zulu7
echo "export JAVA_HOME=/Library/Java/JavaVirtualMachines/zulu-7.jdk/Contents/Home" >> ~/.zshrc
I had to enter my password for installing zulu7. You may need to modify the last command if you are using a different shell.
How about Netbeans, here is an article how to set it up with NB7:
http://netbeanside61.blogspot.com/2011/06/downloading-openjdk7-binary-for-mac-os.html
Maybe similar steps for Eclipse.
As of April 27th there is an offical Oracle release of Java SE 7u4. Download the disk image and run the installer - then see the Mac readme.
As of December 2017, previously posted links don't work, but JDK 7 can still be downloaded from Oracle Archives (login required):
http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html
The instructions by peter_budo worked perfectly. I had to add the jars under /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home/jre/lib/ to my IntelliJ project libraries. Now it works like a charm. Note that I didn't need my IDE itself to run under 1.7; rather, I only needed to be able to compile and run against 1.7. I'll most likely continue to use Apple's JRE for running the IDE since it's probably more stable with respect to graphics routines (Swing, AWT). Like the OP, I was really keen on testing out the new NIO2 API. Looking good so far. Thanks, Peter.
What worked for me on Lion was installing the JDK7_u17 from Oracle, then editing ~/.bash_profile to include:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_13.jdk/Contents/Home
Now, Use command
Update 2020: 04
To install Java7 with homebrew run:
brew tap homebrew/cask-versions
brew cask install java7
Hope this help.
I updated to Yosemite and Android Studio wouldn't clean my projects or Run them on virtual or real device because of the following error:
Failed to complete Gradle execution.Cause:Supplied javaHome is not a valid folder. You supplied: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
After some research and trouble shooting, I found that the JDK file that was being pointed to at "/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home" wasn't there; all of "JavaVirtualMachines/1.6.0.jdk/Contents/Home" was missing from "/System/Library/Java". So, I copied "JavaVirtualMachines/1.6.0.jdk/Contents/Home" over from "/Library/Java/" to "/System/Library/Java/" and cha ching! I was back in business.
