接口中的静态方法需要-target:jvm-1.8 [英] Static methods in interface require -target:jvm-1.8

问题描述

我正在使用gradle 4.5，带有JDK 1.8.0_162的scala 2.11.11/2.12.4构建scala项目，并且在我升级到scala 2.11.12之前，它运行良好.使用2.11.12时，我会不断出现编译错误

I'm building scala project using gradle 4.5, scala 2.11.11/2.12.4 with JDK 1.8.0_162 and it was working fine until I upgrade to scala 2.11.12. With 2.11.12 I keep getting compile error

Static methods in interface require -target:jvm-1.8

我一直在尝试在Google中搜索并添加诸如此类的东西

I've been trying to search in google and add couple of stuffs like

ScalaCompileOptions.metaClass.useAnt = false

或

targetCompatibility="1.8"

但他们都无法解决问题.

but none of them fix the issue.

推荐答案

好吧，在为这个问题苦苦挣扎了几周并决定在SO上发表文章之后，我尝试用gradle进一步摆弄，终于解决了问题.

Ok, after struggling with this problem for a few weeks and decided to post on SO, I try to fiddle further more with gradle, I finally managed to fix this problem.

结果是我必须将这两行添加到gradle中

Turns out that I have to add these two lines to gradle

project.tasks.compileScala.scalaCompileOptions.additionalParameters = ["-target:jvm-1.8"]project.tasks.compileTestScala.scalaCompileOptions.additionalParameters = ["-target:jvm-1.8"]

project.tasks.compileScala.scalaCompileOptions.additionalParameters = ["-target:jvm-1.8"] project.tasks.compileTestScala.scalaCompileOptions.additionalParameters = ["-target:jvm-1.8"]

这可以解决问题，并且不会再次出现.

This is fixing the issue and it doesn't come back.
