Question

试图在playframework的github页面上解决一个简单的问题，但为此，我必须构建文档。

根据他们的readme，我必须使用 sbt run这样做，但是最后（大约20分钟后），我得到一个错误：

所以我开始调查。我设置了一个新的Ubuntu Desktop 18.4副本，安装了Java 8，Sbt，将堆大小增加到2 GB，然后重试。不幸的是，结果相同。

为了完整起见，这是我的Java版本：

java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)

sbt run之后的前几行还建议由sbt导入的scala版本：

Getting org.scala-sbt sbt 0.13.17  (this may take some time)...

有人知道我的配置是否有问题（或者因为我已经在Windows 10 PC，Fedora 28和最新的Ubuntu 18.4上进行了测试而配置），或者我做错了什么？

Answer 1

说实话，我找到了答案。尚不清楚我是否需要在sbt publishLocal之前运行sbt run。有时我还有其他一些错误，例如“找不到X”，然后仅用以下命令构建软件包：

cd $PLAY_HOME/framework
sbt compile doc package

玩得开心！
