java – 如何在IntelliJ中运行Play Framework 2.1项目？

https://www.jetbrains.com/help/idea/getting-started-with-play-2-x.html#run_debug_playApp

首先,我尝试通过右键单击应用程序并选择“运行播放2应用程序”来运行它.它不会运行,它给了我这个错误：

sbt.IncompatiblePluginsException: Binary incompatibility in plugins detected.

在对该问题进行一些研究后,我将-Djline.terminal =添加到我的JVM选项中并再次尝试.这次它运行了,但是当我尝试在浏览器中打开一个页面时出现了这个错误：

Global : Unsupported major.minor version 52.0

最后,我尝试将我的项目重新导入intellij.在它导入之前,它迫使我将build.properties中的SBT版本从0.12.2更新为0.12.4.我这样做了,但仍然遇到上面列出的相同错误.

注意：我将Java 7设置为我的JDK.

这是完整的堆栈跟踪：
