还是Spark编译问题

Question

Failed to execute goal net.alchim31.maven:scala-maven-plugin:3.2.2:compile (scala-compile-first) on project spark-sketch_2.10: Execution scala-compile-first of goal net.alchim31.maven:scala-maven-plugin:3.2.2:compile failed. CompileFailed -> [Help 1]

我按照您的课程和自己百度的，更改了scala版本之后还是报这个错

已经使用了这个命令

./dev/change-scala-version.sh 2.11

warn图片

添加-X之后的报错截图

将zinc加速服务停止是这样吗？

<useZincForJdk8>false</useZincForJdk8>更改为false之后还是报错

编译之前，jps下，把没用的进程全kill掉

  按照您的操作 kill -9  进程号 了，还是报同样的错误，重新再编译了一次，显示这样的warn
  warn] Pruning sources from previous analysis, due to incompatible CompileSetup.
  [info] Compiling 40 Scala sources and 8 Java sources to /root/source/spark-2.1.0/streaming/target/scala-2.11/test-classes...

  warn不用管的，别error就行
