使用maven编译时出现编译错误

[ERROR] COMPILATION ERROR : 
[INFO] -------------------------------------------------------------
[ERROR] Unable to locate the Javac Compiler in:
  C:\Program Files\Java\jre1.6.0_05\..\lib\tools.jar
所以我设置了
JAVA\u HOME
环境变量,但没有任何优势。错误似乎是maven在jre路径中搜索java编译器,而不是在
java\u HOME

  • JAVA\u HOME
    C:\Program Files\JAVA\jdk1.6.0\u 05

  • 安装的JRE是
    C:\Program Files\Java\jre1.6.0\u 05

  • 我的
    路径
    变量是:

C:\Program Files\PC连接解决方案\;D:\alfrescoplatform\ImageMagick;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\system32\Wbem;C:\Program Files\ImageMagick-6.7.3-Q16;C:\ProgramFiles\Java\jdk1.6.0\U 05\bin

这是我的详细记录

如果您对此有任何想法,请告诉我。

尝试将
vm
参数添加到
eclipse.ini
文件中

-vm
C:\Program Files\Java\jdk1.6.0_05\bin\javaw.exe

我遇到了完全相同的问题,尝试了这些解决方案但没有成功:


什么对我有用:

  • 单击绿色运行按钮旁边的小向下箭头
  • 选择运行配置
  • 在JRE选项卡上,选择Alternate JRE,然后选择所需的目标(如果该目标不在列表中,请单击Installed JRE将其添加到中)

您的JAVA\u主页是C:\Program Files\JAVA\jdk1.6.0\u 05

方式1:以下步骤适用于Eclipse:

  • 转到窗口->首选项->Java->已安装的JRE
  • 将现有JRE位置编辑为:Set JRE Home=JAVA\u Home或JAVA\u Home\JRE(在您的情况下,路径应为C:\Program Files\JAVA\jdk1.6.0\u 05或C:\Program Files\JAVA\jdk1.6.0\u 05\JRE)
  • 单击完成并确定按钮
  • 方式2:设置JRE系统库的另一种方式:

  • 打开eclipse并右键单击eclipse项目属性
  • Java构建路径->库
  • 选择JRE系统库->单击编辑按钮
  • 单击“已安装的JRE…”按钮
  • 将JRE编辑为:设置JRE Home=JAVA\u Home或JAVA\u Home\JRE
  • 方式3:以下步骤也应有效:

  • 转到窗口->首选项->Java->已安装的JRE
  • 选择您正在使用的JRE
  • 按编辑->添加外部罐子
  • 浏览到Java\jdk1.6.0_05\lib,选择tools.jar并按Enter键
  • 单击完成并确定按钮

  • 你能把
    mvn--version
    的输出包括进来吗?(在设置
    JAVA\u HOME
    之后,你肯定启动了一个新的命令窗口,对吧?)我只是在eclipse中使用maven插件。
