For some unknown reason, whenever I run gradle clean build after I start my notebook it works as expected. When I try for the second time, I always get
Unable to delete directory 'C:\_d\mycompany\WSs\demo\build'

I found someone failing quite similar problem but using Android Studio/Ubuntu (I am using IntelliJ Community/Windows 10): other question
I tried carefully all recommendations and none of them fixed my issue. I only get it working back if I restart my Windows and just work one time.
Some of the recommendations are:
1 - Close the studio and go to the path the issue is located at and delete the folder there.
I tried close IntelliJ and I can't delete the folder straight
2 - File > Settings > Build, Execution, Deployment > Instant Run > Uncheck this Check box (Enable Instant Run to hot swap code)
There is no such optional in my IntelliJ

The problem is that you have multiple Gradle processes that are still holding locks to your files.
You can try running gradle --stop when this happens to stop any daemons that are running in the backgorund (this usually helps).
You can also check the state of your daemons by running gradle --status. For me this outputs:
No Gradle daemons are running.
Only Daemons for the current Gradle version are displayed.
See https://docs.gradle.org/6.5/userguide/gradle_daemon.html#sec:status
If you see something there it might be a problem.
Using --no-daemon and --no-parallel might help, but they would just hide the underlying problem.
In my case when this happened I realized that I had processes running in the background because of tests never finishing. Check all your threading and/or coroutine usage for unclosed / unfinished processes.
One other case when this happened to me is when I was using ProcessBuilder to start another Java process and it didn't exit.
Just rename the " build " folder.
In my case, I experienced this error after I ran a Gradle command as the root user in Linux.
After switching back to a regular user, Gradle gave me the above error. When I tried to remove the build directory using rm -rf build/, I received a "Permission denied" error. You can solve this problem by removing the build directory as the root user.
For me the files where under a different user and the group and the permissions were not sufficient to write to the files of the directory in question.
Try checking who the user of the project files are with ls -al
If the project and the sub directories and files are under a different user. You can run sudo chown -R [new_owner] [project_folder_name] The flag -R here recursively changes owner for the sub files and sub dirs.
You can also add additional permissions to the group (if the user belongs to the group) or even change the group (if the user does not belong to the group). The basic idea is giving the user enough permission (rwx) to use files.
In Windows 10 Kill all Java TM instances by running this command on command prompt :
TASKKILL /F /IM java.exe
Or you delete your app installed on your phone and reinstall it again.This solved my problem
As I have faced similar kinds of errors during the flutter app development, I have figured out which process is blocking the running app. So I have just ended Open JDK from the Process list and then retried running the app without debug mode and it's working. The thing I learned here is that we have multiple development environments running in the background so we have to determine which process is blocking others.
Delete build folder in this path : your project\app . Then rebuild project.
If you are running windows 10, Go to task manager and end the following task
.......................
Java Platform SE binary
There might be more than one above mentioned task just end all of them and rebuild works
I went to my file system and deleted the file manually. Restarted my android
I'm new to Gradle and while trying to install Gradle in my PC with Windows OS, I got the below mentioned error
Error: Could not find or load main class org.gradle.launcher.GradleMain
Only thing I did is that I followed the gradle installation steps given in gradle site Gradle installation and typed
gradle -v
in command prompt and I got the above mentioned exception. Any clue as to what had happened and how to resolve it.
This is what I have done :
Downloaded the zip file
Copied 'gradle-3.5' from the zip file to a folder I created in C drive (C:\Gradle)
Set GRADLE_HOME to 'C:\Gradle\gradle-3.5'
Set Path to '%GRADLE_HOME%\bin'
Opened cmd and typed gradle -v and got this error
I stopped all gradle daemons by running ./gradlew --stop and the error was resolved for me.
Basically this means that Gradle can't find your gradle/wrapper/gradle-wrapper.jar.
You have to follow Step 3 and setup environment variables:
Microsoft Windows users
In File Explorer right-click on the This PC (or Computer) icon, then
click Properties -> Advanced System Settings -> Environmental
Variables.
Under System Variables select Path, then click Edit. Add an entry for
C:\Gradle\gradle-3.5\bin. Click OK to save.
Source: https://gradle.org/install#configure
The easiest way, is to simply use gradlew.bat in your project and it will auto download Gradle for you!
I had the same issue after I removed the cache, the Gradle worker was running and I was getting this error
Error: Could not find or load main class worker.org.gradle.process.internal.worker.GradleWorkerMain
Steps I performed to resolve the error
Use gradle --stop or ./gradlew --stop
Delete the workerMain.lock file under $USER/.gradle/caches/version/workerMain
re-run the Gradle command
Every time I execute a gradle command on Mac I get a message saying:
"This build could be faster, please consider using the Gradle Daemon: https://docs.gradle.org/2.10/userguide/gradle_daemon.html"
I've created a gradle.properties file with the line org.gradle.daemon=true as mentioned in the web page given in the message. However no matter what I do, I still continue to get that message.
If I execute the command
gradle --daemon
then it executes successfully, but still next time I do something I get that message about it could be faster and builds are just as slow as before I started the daemon.
My installation directory is no /Users/username as in gradle_daemon.html as I'm falling a Udacity course (https://www.udacity.com/course/viewer#!/c-ud867/) and they recommend installing it to /usr/local/gradle
How can I actually get the gradle dameon to work and get rid of that could be faster message?
(Using Gradle version 2.10)
just put
org.gradle.daemon=true
in the ~/.gradle/gradle.properties file. Then each build on your machine will use the gradle wrapper and the message dissapears.
The page doesn't say anywhere that gradle must be installed in /Users/username. It says that this directory is your home directory, and that's where the .gradle/gradle.properties file must be located. The place where gradle is installed is irrelevant.
I used gradle build command in Centos 7 terminal and I got output:
FAILURE: Build failed with an exception.
* What went wrong:
Could not create service of type InitScriptHandler using BuildScopeServices.createInitScriptHandler().

For me, killing the Gradle daemon (gradle --stop) really helped and fixed the issue.
Try setting your GRADLE_USER_HOME variable to a folder where you have valid access. Then this error will go away.
For ex: I faced the same issue today while I was running gradle clean command on a new slave machine.
My Gradle version was 2.3.
With --stacktrace, I came to know it was trying to create .gradle folder for storing Gradle's cache data (while I invoked Gradle to run clean task on the slave) and it was trying to create that folder under /some/location/where/gradle/exists OR some /path/location/xxx/yyy where the user which was running Gradle on the slave machine didn't have valid access to write (create folder/files).
i.e. the user which I used to connect from Jenkins machine to the slave didn't have write access to touch/mkdir anything in the default location (where Gradle thought, OK I should create .gradle folder here).
To fix it, I added the above GRADLE_USER_HOME variable in the slave's ENVIRONMENT Variable section. Now, as I have valid access in my home directory, I was OK.
Setting:
GRADLE_USER_HOME=~/gradle_2_3_cache/.gradle
resolved the issue.
You can set it to ~/.gradle as well. But I set it under a custom folder inside my ~ home directory (gradle_2_3_cache). This will help me in case I have another job/build run running on the same Slave machine but with a different Gradle version for ex: 2.5 etc version and if I want the .gradle cache for 2.3 and 2.5/x version in separate folders.
NOTE: When using parallel section within Jenkinsfile, it's best to avoid Gradle greatness (i.e. using same Gradle's cache i.e. using same GRADLE_USER_HOME) as otherwise, you'll land into a mine of interesting issues as listed here: Jenkins - java.lang.IllegalArgumentException: Last unit does not have enough valid bits & Gradle error: Task 'null' not found in root project
The Problem solved by simply using "sudo" and giving access to gradle to create a folder and write cache. use:
sudo ./gradlew
If you using wrapper gradlew, in root make directory .gradle_new
mkdir .gradle_new
chmod -R 777 .gradle_new
and run gradlew with arguments:
--project-cache-dir .gradle_new
Restarting the machine solved the issue.
I had the same problem.
For me it worked after I exclude the .gradle folder if you can not delete try to rename.
If you have just updated your JDK version and you have set up a Gradle wrapper in your project, you may want to double-check the wrapper version supports your new JDK. If not, consider removing wrapper-related files from the project (gradlew, gradlew.bat and gradle/wrapper/*) and re-generating them with the Gradle CLI, like so:
gradle wrapper --gradle-version <new-version-number>
e.g. gradle wrapper --gradle-version 4.10.2
This of course assumes your Gradle installation is up-to-date. If not, you will want to update that first.
I got the same error, got rid of it by using the correct version of Java / JDK. I was trying to build a Java 8 project with the Java 11 JDK. Check which version of Java JDK you are using.
To develop projects with different Java versions in parallel I now use jEnv to manage the different JDK versions: http://www.jenv.be/
This is a permission issue.
do a
gradle wrapper --stacktrace
you should see something like this
Failed to create parent directory '/home/cloud_user/my-project/gradle' when creating directory '/home/cloud_user/my-project/gradle/wrapper'
the user, cloud_user, has no permission to the directory
make cloud_user owner of the folder
sudo chown -R cloud_user:cloud_user /home/cloud_user/my-project/
I got this error when running code in IntelliJ Idea, and
gradle --stop
really not helped, as it said that "No Gradle daemons are running."
But simple kill of all gradle processes helped:
ps aux | grep gradle
kill -9 $PID
Permission issue. This fixed the issue for me:
sudo chown -R $USER dir
For me this was to do with Java versions. I have Java 10 installed and as the default Java on my system. Setting a JAVA_HOME pointing at Java 8 was sufficient for the project (graphql-spring-boot) to build.
If using the "Invoke Gradle script" build step, click on Advanced to reveal additional options. Locate "Force GRADLE_USER_HOME to use workspace" and check it.
If anyone is still struggling with this, my issue was caused by Microsoft preventing Java from running due to Controlled Folder Access security restrictions.
I didn't get the popup notification since my computer is set to Do Not Disturb Mode. Once I allowed access, Gradle ran fine.
For future reference.
I had the same problem, the issue was that the antivirus was blocking OpenJdk platform binary and java.exe which prevented android studio from being able to modify the files
I ran into this exception when trying to build a project that was mounted as read-only filesystem in a VM. The project set its own gradle cache so changing GRADLE_USER_HOME did not work. I had to change the filesystem to be read/write.
You Just Have to Run it under the super user (sudo ....) it works for me
If you run Docker-in-Docker and mount the project directory from docker host directly to docker container:
-v ${PWD}:/path_to_project -w /path_to_project
the owners are different and docker container user (either gradle or root) can't override/delete ./buildSrc/build or ./build/
One of the fixes - copy the sources inside the container to temporary directory and build there.
Smth like this (first mounted to project, but then copied to project-copy to "decouple" with the host system real files and run the build in the copy):
docker run -v "${PWD}":/home/gradle/project -w /home/gradle/project-copy \
--rm \
--entrypoint sh \
gradle:5.5.1-jdk11 \
-- -c "cp -r -T /home/gradle/project ./ && ./gradlew build"
In my case I had bad credentials to private Maven repository. JIdea does not show the inner exception but running gradle build reveals the problem immediately.
I used a Gradle project in Eclipse, Eclipse's Gradle was giving that error. When I installed NetBeans and its Gradle Plugin, the problem has gone, project was building okay. Another way to circumvent this error was using commandline ./gradlew , project also built successfully.
It seems that Eclipse's era is over, they appear to be unable to follow the progress.
This can happen if you run Gradle commands from separate terminals at the same time - I assume Gradle somehow locks ~/.gradle when it is running to prevent any problems.
I had that same error, while running gradle with java 14 (openjdk) as my default java implementation. Setting default java back to java 8 solved the issue
sudo update-alternatives --auto java
just run (taskkill /im java.exe /f) in command
In my case the error was different but I landed here, my error was:
Could not create service of type ExecutionHistoryStore using ExecutionGradleServices.createExecutionHistoryStore().
> Timeout waiting to lock execution history cache (/Volumes/Extreme SSD/FlutterProject/test/android/.gradle/6.7/executionHistory). It is currently in use by another Gradle instance.
Owner PID: unknown
Our PID: 94001
Owner Operation: unknown
Our operation:
Lock file: /Volumes/Extreme SSD/FlutterProject/test/android/.gradle/6.7/executionHistory/executionHistory.lock
It happens when you try to run flutter run from two separate terminals.
So I solved it by executing cd <projectPath> && flutter run from the active terminal which I was using first.
Basically, while executing some Gradle command, in this case building an android file, the terminal locks down some Gradle PID, so either you stop them or just simply use that terminal.
in my case manual removing the .gradle and .idea folders helped me
you can find them in the Android Studio if Project view selected
after this just clean and rebuild app
kill -9 'pid' solved the issue. pid can be found in the error log
To fix this issue, restarting your PC is the main solution
I got the same issue and for me worked below command.
./gradlew --stop
After that restart my system and wipe data of simulator and run again everything works fine.
