In my case it happens because of Lombok, so fix the issue.

In my case this line on SpringToolSuite4.ini produced that error when i tried to do Clean on my project:

-Xbootclasspath/a:lombok.jar

Solution for me: i deleted that line.

I faced a similar issue when I updated my STS4 version while using old lombok jar version. My problem was solved by updating lombok version to its latest.

I resolved this by reverting the .cproject file in my project folder to an older version (which was created when I setup the project for the first time)

This kind of problem is very rare but we have the solution, If you are using gradle or maven then first close your project and delete from eclipse (remember don't delete from disk), then delete the files and directories from your project:

.settings/
.project
.classpath
.gradle/

then reimport the project in eclipse and you are done. you will no longer face the error like "Errors running builder 'Java Builder ' "

I solved my build error in eclipse juno by restoring my eclipse work space. Reason being, the .metadata was corrupted so whenever i could try to build the project it could sometimes fail. Therefore you have to backup yr projects in a folder outside the main work space then deleted the whole work space folder. Restart eclipse and create a new work space and import yr projects into yr new work space. Everything will work normally after that.

Thanks Umark
