今天在Eclipse的Juno和Mars版本中,去执行Maven -> Update Project的时候出现了一个错误:
Errors occurred during the build. Errors running builder 'Maven Project Builder' on project 'xxx'.
以及
java.lang.NullPointerException
Errors running builder 'Maven Project Builder' on project 'xxx'.java.lang.NullPointerException
经排查后发现原因是由于这两个eclipse版本中已经自带了m2e的插件,而我刚刚自己又安装了m2e插件,冲突引起来的。在eclipse的Help - > Install Software中点击如下图所示的What is already installed?即可将已安装的m2e插件删除。
