试图迁移到java OpenJDK: activator1.3.9，Intellij无法工作。

Question

我正在尝试迁移到java OpenJDK。我有一些工作项目，但是在安装OpenJDK之后，什么也不起作用。我用java -version验证了-version安装，它的响应是: openjdk版本"12.0.1“2019-04-16 OpenJDK运行时环境(build 12.0.1+12) OpenJDK 64位服务器VM (构建12.0.1+12，混合模式，共享)

所以它的安装正确。在切换之前，我对项目进行了测试，以确保一切正常。

现在试图使用激活器启动intellij中的play框架项目，就像往常一样，但是shell存在错误。

是否有人让OpenJDK使用play框架和intellij？如果是这样的话，需要做什么呢？

sbt shell错误：

Answer 1

官方SBT文档推荐的JDK在30.04.2019上为1.8：

安装JDK (我们推荐Oracle 8或OpenJDK 8)。

SBT1.3.0里程碑版本是在OpenJDK 11上测试

所有项目现在都使用AdoptOpenJDK JDK 11进行测试。

而目前稳定的版本是1.2.8。SBT是用Scala和JDK 12兼容性说明开发的。

Scala还没有在JDK 12上进行广泛的测试。

鉴于以上所述，SBT目前可能与JDK 12不完全兼容，因此我们可以考虑按建议的这里下调评级。
