every pioneers,
I want to try to build Spring Roo 2.0.0.M2(http://projects.spring.io/spring-roo/) with its saying of STS 3.7.0 and JDK 1.7.0_45, and I couldn't find the solution even according the post on other sites or on " Builds failing after upgrading to Java7, Missing Tools.jar and bad class versions " .
The error messages on auto generated POM.xml are:
??????????????????????????????????????
You need to run build with JDK or have tools.jar on the classpath.If this occures during eclipse build make sure you
run eclipse under JDK as well (com.mysema.maven:apt-maven-plugin:1.1.3:process:default:generate-sources)
org.apache.maven.plugin.MojoExecutionException: You need to run build with JDK or have tools.jar on the
classpath.If this occures during eclipse build make sure you run eclipse under JDK as well at
com.mysema.maven.apt.AbstractProcessorMojo.execute(AbstractProcessorMojo.java:362) at
....
?????????????????????????????????????
Even I have tried: add JDK1.7.0_45 path but not JRE path in STS project, and even I added tools.jar directly in project build-paths, and even I use "mvn generate source" and add the generate jar into source path. The error about apt-maven-plugin:1.1.3 is still there.
Is there any person who can help? I will try to use old apt-maven-plugin latter.

Setup:
Intellij IDEA community edition 2020.2
Spring Bott starter parent: 2.3.5
Java 11
WRAPPER_VERSION: 0.5.6
mvn 2
Hi,
I googled a lot e.g. here but I just can't fix it.
I created a new mvn spring project with Intellij. When I commit the project I get errors detected by code analyses in class: MavenWrapperDownloader.java.
e.g. It reports:
Cannot resolve symbol String
I tried:
invalidate caches and restart
delete .idea folder and reimport
checked sdk setup
mvn reimport
mvn clean and then rebuild (while the build is always successful)
I'm pretty new to maven. I guess the scope of the mvn package might be wrong because the build process works as expected.
UPDATE:
I reinstallt my openjdk11. No success. Then I found out that my .mvn/wrapper dir is not set as source root. I know that was never the case in my other projects. As a trial I've set my .mvn folder as source root and now the MavenWrapperDownloader.java file is recognized as a java class and the compiler interprets the symbols. But now there is another error. It says I have to define a package name for that class because the class does not have one per default. It is pretty strange to me. I also tried to use another spring boot starter version but nothing changed
When I execute Analyze->inspect code I get the following:
I had the same problem and File -> Invalidate Caches/Restart fixed it - at least for now.
IntelliJ Ultimate 2020.3
Spring Boot Starter Parent 2.4.2
Java 15
Maven 4.0.0
Maven Wrapper 0.5.6
The easiest solution is to generate your project again with Spring Starter.
After you set up everything you need at pom file -> Generate -> Download it.
Open with your IDE and copy-paste all code sources which you have already written.
Dear Stackoverflow Community, I have the following problem with my spring boot starter application. I imported the starter project as a new maven project into IntelliJ. But IntelliJ does not find the dependencies I specified in the pom.
Image of my Application Class:
If I try to run the project I get the following error message.
Image of the Error Message:
I already tried everything from re-installing IntelliJ to re-importing the project or redownloading the dependencies. I simply dont know why IntelliJ doesn´t find the dependencies.
My pom.xml looks as following
Image of my pom.xml:
The first time I tried to edit the pom.xml it said to me "this file does not belong to the project". Maybe this might be one reason.
Running the whole thing with 'mvn install' or 'mvn clean verify' works.
Try this and then build: mvn -U idea:idea
Had the same problem. I have tried everything: invalidating cache, deleting the whole .m2 folder, changing settings, reloding the project, nothing helped.
The solution for me was to delete the .iml files which are IntelliJ module files used for keeping module configuration. After reopening the project it worked.
The idea was not mine, I found the hint here: https://intellij-support.jetbrains.com/hc/en-us/community/posts/203365204--package-does-not-exist-error-despite-autocomplete-being-aware-of-them
Sometimes your workspace could get corrupted.
In my case, I tried to Reload the project and it worked
in my case changed JDK version in Maven importer from JDK 11 to my local JDK version 1.8
Here is how my IntelliJ settings for spring boot application looks like
Click open -> browse your workspace -> and select POM.xml file
Check this in your intelliJ settings
Do this too [Settings --> Maven --> Importing]
I just had the same issue. My solution was to remove all dependencies from the pom, reload via maven -> Reload All Maven Projects. Run mvn compile. Add dependencies back to the pom, maven -> Reload All Maven Projects. Run mvn compile.
Now the Intellij build works.
You need to change Maven's JDK for importing option from Project JDK to the Path variable for Java on your machine.
You can get to this by going to Settings -> Build, Execution, Deployment -> Build Tools -> Maven -> Importing. Scroll down to the bottom and look for JDK for importing:. Select from the list the path variable for JAVA.
For Windows users, JAVA_HOME should be an option in the drop-down list.
Follow these steps, your problem should be solved. You just need to add Spring-framework-starter-web and Spring-framework-starter-tester from your pom.xml file.
Got to generate(ALT+Insert)
Add dependencies
Search "springframwork"

In my case, adding the project as maven project helped .
Background:
I am developing Maven multi module project.
One of the module is common module needed by other all modules.
This module contain CommonClassA.java.
common module is properly compiled.
It is installed into maven local repository properly.
One of the class(Billtype.java) in other module (EmployeeBilling) refers this class(CommonClassA.java).
Maven Dependency for common module is properly specified in pom.xml of EmployeeBilling module.
Problem:
While compiling EmployeeBilling module it throws
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project EmployeeBilling: Compilation failure
[ERROR] \MyWorkspace\Biz\EmployeeBilling\src\main\java\com\employee\Billtype.java:[79,19] error: cannot access CommonClassA
[ERROR] -> [Help 1]**
Supporting details:
dependency defined in EmployeeBilling> pom.xml:
Other classes from common module seems accessible as no error observed
There are no other errors like Class not found/file not found.
The class CommonCLassA implements Serializable
Same error occurs from Eclipse as well as commond line
I am using M2E plugin
Tools:
jdk1.7.0_02
OS: Windows 7
Eclipse JUNO and apache-maven-3.1.0
Thanks in advance!
If project builds properly using eclipse compiler then it should work with Maven.
Few things to check if its not working with maven:
Manually check in repository that jar is installed properly and it contains your class file.
Try to build project using locally installed Maven instead of maven in eclipse.
Set -DskipTest=true while installing your jar, as it can cause issues at times.
If these steps don't work then show us your pom.
With no more information it's hard to find the cause. But I also had this problems now and then, and there are some things which could go wrong:
Are you using the right JAVA version (everywhere) ?
... and the right java PROVIDER? (Oracle, IBM, OpenJDK) In my case it's often this issue, I'm sometimes bound to IBM JDK, although I try to use Oracle where I can and this sometimes breaks my build.
Is the right maven dependency VERSION used? If you depend on it multiple times, and all in the same (lower than root) dept of dependencies, Maven will just "choose" a version. It could be that thát version is incompatible with your code of thát particular dependency
Skipping tests sometimes WORKS! It has something to do with maven phases and getting stuff ready for using it elsewhere.
Good luck :)
I had the same problem. Even the jar dependency has the required class files. Finally I deleted the local maven repo and restarted the build. Now it worked without any issue.
It looks like you are using an old version of maven-compiler-plugin (v2.3.2).
I suggest you upgrade it to 3.x. it won't magically fix your issue but it will definitely give you better / more detailed error message.
I created a dynamic web project in eclipse for a web service with axis2. I then converted it into Maven project, I'm able to compile and generate war file in eclipse, but when i deploy it on server and try to build it with Hudson-3.0.0 it gives me following error:
mojoFailed org.apache.maven.plugins:maven-compiler-plugin:2.3.2(default-compile)
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project WebServices: Compilation failure
Unable to locate the Javac Compiler in:
C:\Program Files (x86)\Java\jre6..\lib\tools.jar
Please ensure you are using JDK 1.4 or above and
not a JRE (the com.sun.tools.javac.Main class is required).
Please Let me know what's wrong with it!
I have exactly the same problem, ever since I upgraded Hudson from 2.2.1 to 3.0.1.
Both JAVA_HOME environment variable and JDK in hudson configuration point to JDK and not to JRE.
If I run mvn compile in the workspace directory of the job, everything works well.
Looks like the hudson cannot find java_home.
In hudson settings java.home property is set correctly ?
Does any other java projects builds successfully ?
Did you do what the exception said yet?
Please ensure you are using JDK 1.4 or above and
not a JRE (the com.sun.tools.javac.Main class is required).
Sounds like you don't have Java installed. So install it.
I use the built-in maven of MyEclipse 8.5 to create maven projects.
It shows the following error:
Image is here:pic
Sorry, because I'm new I can't post pictures here yet.
I did it twice on two computers (both are MyEclipse 8.5), but the error was the same.
I use a Eclipse to do the same job and it is successful.
But when using MyEclipse 8.5 to do the job if check "create a simple project (skip archetype selection)" during the process, the project can be created and no error happens, but there is no the folder "Maven Dependencies" in the project created in Package Explorer.
Is this a bug of this version of MyEclipse? Because Eclipse Indigo works fine on this.
If you create a simple project, the folder Maven Dependencies is missing simply because there are no Maven Dependencies in a simple project. Just add a dependency, and the folder Maven Dependencies should be created with your dependency in it.
