Google App Engine JSP无法部署：java.lang.RuntimeException：无法获取系统Java编译器。请使用JDK，而不是JRE [英] Google App Engine JSP can't deploy: java.lang.RuntimeException: Cannot get the System Java Compiler. Please use a JDK, not a JRE

问题描述

这有希望有些简单，但是除了部署到GAE之外，Eclipse一直工作得比较好。

this is hopefully something simple but... Eclipse has been working relatively fine for everything except deploying to GAE.

我可以在本地运行我的GAE应用程序，但是当我尝试部署到Google时，我会收到以下消息：

I can run my GAE app locally, but when I try to deploy to google, I get this message:

java.lang.RuntimeException: Cannot get the System Java Compiler. Please use a JDK, not a JRE.

我已经将构建路径设置为JDK。

I have set the build path to JDK.

当尝试从多个系统（win7和win8）部署同一个项目时，也会发生这种情况，所以我怀疑问题是与项目本身有关。这个特定的项目已经存在，已经在谷歌上运行多年了。

It also happens when trying to deploy the same project from more than one system (win7 and win8) so I suspect the problem is to do with the project itself. This particular project is existing and already running on google for years.

有趣的是，当我的应用程序中有.jsp文件进行部署时，这个错误只会显示出来。如果我删除jsp文件，它会部署没有错误。 （有点需要jsp文件）

Interesting that this error only shows up when I have .jsp files in my app to deploy. If I remove the jsp files, it deploys without error. (kinda need the jsp files tho)

谢谢

推荐答案

我有同样的问题并且能够在强制Eclipse在我的SDK目录（Win 7 64bit）中使用
JRE之前成功部署。要强制Eclipse使用特定的JRE，请参阅此。看来Eclipse使用的JVM，应用程序引擎产生的JVM，& appconfig使用的JVM应该是一样的。希望这也有助于你的情况。

I had the same problem and was able to deploy successfully after forcing Eclipse to use the JRE within my SDK directory (Win 7 64bit). To force Eclipse to use a particular JRE see this. It seems that the JVM that Eclipse uses, the JVM that app engine spawns, & the JVM that appconfig uses should all be the same. Hope this helps w/ your situation as well.
