Building Java project shows error: "Build failed, do you want to continue?"

[niiiksh]

Building Java project shows error: "Build failed, do you want to continue?" when the build is actually completed because when I click "Proceed" it will run updated version of my code and autobuild enabled when I type new code. javatest.zip

Environment

• Operating System: Windows 10 Pro (1709)
• JDK version: 9.0.4
• Visual Studio Code version: 1.21.1
• Java extension version: 0.22.0

Steps To Reproduce

1. Open attached java project in Visual Studio Code with Java Extensions Pack installed
2. Start debugging by F5

javatest.zip

.log

Current Result

Build error

Expected Result

No error

Additional Informations

I have another project built with this extension and it builds without any error.

My problem was that the promt showed build failed but if i click on proceed it work just fine. to remove the annoying promt all i did was: Go to java extension pack-> click on any extension settings icon -> click extension settings -> uncheck (Java › Debug › Settings: Force Build Before Launch)

I hope this answer helps

Damn, this issue is now over 3 years old, still getting notifications on this

I am getting a buildpath incomplete error on a multi-project build on Quartz. Short version:

• Gradle build files
• java 11.
• The build works from the command line using gradle
• No changes, and it works fine with IntelliJ.
• Runtime works just fine
• Verified the correct version of quartz installed in the classpath; and all dependencies with exact versions used.

Same error posted above.. Has anyone found a way to debug or printout what the compiler is doing?

@n614cd could you, please, attach a project example?

Unfortunately this is private code I am working with. I have tried to strip the project down multiple ways (such as removing the java source files). Once I strip the code from the project (I have tried to remove test code, all code, core libraries...). I am no longer getting the error. Which leads me to believe that the problem is less likely with the build itself, and more likely with some hidden error. Hence why I am trying to work it now before it somehow raises an issue in production.

If a maven module uses Lombok, it will build failed.

I had the same issue but when i deleted the java file containing error in that same folder where current java file is, then warning disappeared. you can also try to delete the file or correct the code in the folder your are working in they error should disappear.

This solve my problem. In my case, I'm using Vscode for developing in Java. For previous configurations (when I was studing Python) VSCode did create a .history folder containing versions of the code. Deleting that folder I could solve the problem.

Thanks!

@DoganM95

I guess you are trying to compile a .java file in a folder hierarchy where other .java files exist and have errors. check your "problems" tab and see if there are any. if so, the project will probably show the error message until all problems are resolved. After that you should stop getting the "Build failed..." Message.

@snjeza I manage to provide a sample project (like @n614cd) which showcases the issue. Please have a look at https://github.com/a-st/vscode-java-issue-495

After opening the project, vscode shows following problems

@a-st This is an upstream buildship issue - https://github.com/eclipse/buildship/issues/1131 You can try the following patch:
