      环境】

      eclipse-jee-juno-SR2-win32-x86_64

      apache-maven-3.0.4

      【Eclipse报错】

      【原因】

      根据错误提示,需要JDK而不是JRE,并且需1.4以上版本。Eclipse的默认运行环境是JRE,而Maven编译需要JDK。

      【排错】

       1. 在cmd中用命令echo %JAVA_HOME%查看环境变量,指向正确。

      2. 修改eclipse.ini文件,加入下面2句,依然不起作用。

      -vm
      C:\Program Files\Java\jdk1.7.0_02\bin\javaw.exe

    复制代码
    -startup
    plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
    --launcher.library
    plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20120522-1813
    -showsplash
    org.eclipse.platform
    --launcher.XXMaxPermSize
    256m
    -vm
    C:\Program Files\Java\jdk1.7.0_02\bin\javaw.exe
    --launcher.defaultAction
    openFile
    -vmargs
    -Xms40m
    -Xmx512m
    复制代码

      3. 在Eclipse->Window->Preferences->Java->Installed JREs->Add...->Standard VM里,JRE home选择
    JDK的目录。再勾选,如下图,问题解决。
