Eclipse Juno使用“Maven Project Builder”构建错误

Question

当我尝试清洁＆amp;构建我的Maven项目我收到以下错误：

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"

任何想法是什么导致了这个？

Answer 1

如果您使用外部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

C：\用户\ sunny.m2 \存储库

Answer 2

与Maven安装点一起，也检查Maven的“用户设置”。我的鼠标指向默认位置，但是我在某个地方也有settings.xml也会导致问题。

Answer 3

我通过更正JDK的eclipse（eclipse.ini）vm值来修复我的问题。
