Question

我在尝试部署到 Google AppEngine 时遇到此错误。我确实选择了 JDK!

我清理了项目，将 Eclipse 重新安装到最新版本，重新安装了所有插件等。我还使用

编辑了 Program Files\Java\eclipse-kepler-4.3\eclipse.ini

-vm
C:\Program Files\Java\jdk1.7.0_17\bin\javaw.exe

在顶部和 -vmargs 之前。

Answer 1

转到安装了 eclipse 的 Eclipse 文件夹(比如 c:\eclipse)。您会发现 eclipse 在启动时使用的 eclipse.ini 文件。添加以下行-虚拟机C:\Program Files\Java\jdk1.7.0_25\bin\javaw.exe

将上面的 java 路径更改为您的 JDK 位置。它应该能够使用此 JDK 并将编译并部署到应用引擎。
