将 play framework 项目更新到 Java 11 并且找不到正确的依赖版本答案

【问题标题】：Updating play framework project to Java 11 and cannot find correct dependency versions将 play framework 项目更新到 Java 11 并且找不到正确的依赖版本

【问题描述】：

将现有的 maven 项目从 Java 8 更新到 11，我正在努力寻找依赖项和插件版本的正确组合。其中一个模块使用 play 框架及其相关依赖项，现在设置如下：

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：我希望将 akka 保持在 2.5.x 版本，因为 2.6.x 需要大量代码更改，但如有必要会转到更高版本

编辑：更新了 SBT 和 Scala 版本，添加了经过编辑的 pom

【问题讨论】：

标签： scala playframework sbt akka java-11

【解决方案1】：

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。我建议升级到 sbt.version=1.2.3

如果您不想升级到更高版本，您正在使用的 Akka 版本应该是不错的。

更新：

我可以看到您将 sbt 版本更新到 0.13.17，并且您尝试使用更高版本，但是您应该忘记 sbt 0.13 并坚持使用 sbt 1.x，因为 sbt 0.13 使用的是 scala 2.10 和 sbt 1.x scala 2.12。

我还注意到您没有 maven-compiler-plugin 的版本标记。如果你使用的是 maven 3，它应该会因为缺少这个标签而无法构建，因为它不是，我猜你使用的是应该升级的 maven 2。您还应该将 3.8.0 版本标记添加到 maven-compiler-plugin。

检查this guide 以了解如何为 java 11 正确配置此插件。您还应该检查其他说明以查看是否所有配置都正确。

【讨论】：

感谢您的回复，抱歉最初的问题是 SBT 版本的拼写错误，我已经使用 JDK 11 推荐的 0.13.17 和 1.1.0 版本（现在也是 1.2. 3）但仍然没有运气
我怀疑您的问题与您的 Maven 配置有关。你能发布你的maven配置吗？
