开发环境:
- java:1.8
- scala:2.10.6
- gradle:2.11
- idea:15
使用gradle构建scala的项目报错
Error:scalac: 'jvm-1.8' is not a valid choice for '-target'
Error:scalac: bad option: '-target:jvm-1.8'
错误原因
在stackoverflow中的回答是:
Gradle by default use the ant task to build Scala code, and https://issues.scala-lang.org/browse/SI-8966 shows that jvm 1.8 was not added as a supported target until Scala 2.11.5.
You can try using the Zinc based compiler with by adding the following the gradle build file.
tasks.withType(ScalaCompile) {
scalaCompileOptions.useAnt = false}
You may also need to add the zinc compiler to your dependency list.
解决方法
解决方法有三个:
1.升级scala版本,把scala升级到2.11就OK了
2.降低java版本,1.7不会出错
3.老外的方式,没做尝试
补充
修改gradle的版本没有效果,其它的构建工具不会出现这个错误
