Eclipse Juno使用“Maven Project Builder”构建错误

Question

当我尝试清理和构建我的Maven项目时，我收到以下错误：

Errors occurred during the build.
Errors running builder 'Maven Project Builder' on project '(Hid Project Name)'.
org/apache/maven/project/MavenProject
Errors running builder 'Maven Project Builder' on project '(Hid Project Name)'.
org/apache/maven/project/MavenProject

与清除所有进程类似，它会抛出以下内容：

Errors occurred during the build.
Errors running builder 'Maven Project Builder' on project '(Hid Project Name)'.
loader constraint violation: loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) previously initiated loading for a different type with name "org/apache/maven/plugin/MojoExecution"

有什么想法导致这个？

如果您正在使用外部maven检查是否已选中

如果它指向localRepository标记中的正确位置，也尝试删除.m2并检查那里的设置文件
