此环境中不提供编译器。也许您正在运行JRE而不是JDK?

我正在使用m2eclipse在Eclipse中编译一个项目。我在Eclipse中设置JDK路径，如下所示:

Windows-->preferences-->installed jres--> jdk1.7.xx  path

但是这显示了一个错误

[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE    rather than a JDK?

当前回答

如果您正在从cmd运行Maven命令，请确保在运行该命令之前设置了jdk路径。在我的例子中，我创建了一个包含以下内容的.bat文件:

set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_60
start cmd.exe /k "cd c:\aem_proj\sis\aau"

其他回答

在Eclipse IDE中，进入Window > Preferences > Java > Installed JREs >并检查已安装的JREs。这里应该有一个带有JDK的条目。选择执行环境，如下所示。单击OK 然后右键单击项目-> Maven ->更新项目

此外，您可能必须更改Maven JRE(参见@jlars62 answer)，如下所示。运行配置，选择Maven构建我正在运行(从左侧面板)。然后，单击JRE选项卡并选择Workspace default JRE选项
