将play框架项目更新到Java 11，无法找到正确的依赖版本
提问于 2020-02-06 07:49:35
将现有的maven项目从Java 8更新到11，我很难找到依赖和插件版本的正确组合。其中一个模块使用play框架及其相关的依赖项，下面是它们的设置：
java: 11.0.5
scala: 2.12.8
sbt: 0.13.17
sbt-compiler-maven-plugin: 1.0.0
sbtrun-maven-plugin: 1.0.1
play: 2.6.21
play2-maven-plugin: 1.0.0-rc5
play2-provider-play26: 1.0.0-rc5
akka: 2.5.27这给了我以下构建错误：
[ERROR] Failed to execute goal com.google.code.play2-maven-plugin:play2-maven-plugin:1.0.0-rc5:enhance (default-play2-enhance) on project services: Execution default-play2-enhance of goal com.google.code.play2-maven-plugin:play2-maven-plugin:1.0.0-rc5:enhance failed: An API incompatibility was encountered while executing com.google.code.play2-maven-plugin:play2-maven-plugin:1.0.0-rc5:enhance: java.lang.NoSuchMethodError: 'scala.collection.mutable.ArrayOps scala.Predef$.byteArrayOps(byte[])'

[ERROR] Number of foreign imports: 1
[ERROR] import: Entry[import from realm ClassRealm[maven.api, parent: null]]注意:我希望保持akka的版本2.5.x，因为2.6.x需要大量的代码更改，但如果有必要，将转到更高的版本

根据scala文档https://docs.scala-lang.org/overviews/jdk-compatibility/overview.html
您的SBT版本与Java 11不兼容。
如果您不想升级到更高的版本，那么您使用的Akka版本应该是好的。
更新：
我可以看到您将sbt版本更新为0.13.17，并且尝试了更高的版本，但是您应该忘记SBT0.13并坚持使用SBT1.x，因为SBT0.13使用scala 2.10，而SBT1.xScala2.12。
我还注意到您没有maven编译器插件的版本标记。如果您使用的是maven 3，它应该会因为缺少这个标记而无法构建，而且由于它不是，我猜您使用的是应该升级的maven 2。此外，您还应该添加3.8.0版本标记到maven编译器插件中。
检查本指南，看看如何正确配置这个插件用于java 11。您还应该检查其他说明，看看是否所有的东西都配置正确。
