此环境中不提供编译器.也许您在 JRE 而不是 JDK 上运行? [英] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

问题描述

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:

I'm compiling a project in Eclipse using m2eclipse. I set the JDK path in Eclipse like this:

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

但这是显示错误

[ERROR] COMPILATION ERROR :

推荐答案

1. 在您的 Eclipse IDE 上，进入 Window > Preferences > Java > 已安装的 JRE > 并检查您的已安装的 JRE.您应该在那里有一个带有 JDK 的条目.
2. 选择执行环境，如下所示.点击确定
3. 然后在您的项目上右键单击 -> Maven -> 更新项目

此外，您可能需要更改 Maven JRE(请参阅 @jlars62 答案)，如下所示.转到 Run -> Run Configurations，选择我正在运行的 Maven Build(从左侧面板).然后，我单击 JRE 选项卡并选择选项 Workspace default JRE

Additionally, you may have to change Maven JRE (see @jlars62 answer) which is as follows. Goto Run -> Run Configurations, selecting the Maven Build I was running (from the left panel). Then, I clicked the JRE tab and selected the option Workspace default JRE
