稍晚，但我有同样的问题，也试图找到解决方案。也许这将来会帮助某人：
问题是Eclipce无法编译文件并引发异常。在我的情况下，修复是：
- 现在移动所有编译源（buildBin文件夹）
- 移动现在所有自定义构建器（.externalToolBuilders），如果你有它，并且所有.settings文件夹
- 重新启动Eclipse并让它构建
- 修复编译问题：）
- 粘贴所有以前删除的文件（不要松开任何设置\建造者）
I am suddenly getting this error from eclipse when compiling.
Internal compiler error: java.lang.NullPointerException at
org.eclipse.jdt.internal.compiler.apt.dispatch.AnnotationDiscoveryVisitor.visit(AnnotationDiscoveryVisitor.java:61)
The project is an android project. Any clues? Don't want to do another eclipse reinstall! Help!
解决方案
Little late, but I had the same problem and also tried to find solution. Maybe it will help someone in the future:
The problem is that Eclipce is unable to compile files and it throws an exception. In my case the fix was:
- Move for now all compiled sources (buildBin folders)
- Move for now all custom builders (.externalToolBuilders) if you have ones, and all .settings folder
- Restart Eclipse and let it build
- Fix compilation problems :)
- Paste back all previously removed files (to not loose any settings\builders)
