使用shadowJar和Scala依赖项时如何解决丢失的conf文件? [英] How can I fix missing conf files when using shadowJar and Scala dependencies?

问题描述

为像我这样将来遇到问题的用户撰写本文.基于Typesafe配置的库通常使用其自己的reference.conf文件并引用某些配置密钥.使用Gradle shadowJAR插件构建胖JAR时，不包含这些文件.

Writing this for users who have future issues like me. Libraries that are built on the Typesafe config typically use their own reference.conf files and refer to certain configuration keys. When building a fat JAR using the Gradle shadowJAR plugin, these files aren't included.

当胖JAR尝试运行时，诸如Spray和Akka之类的依赖项会引发错误.错误如下:

Dependencies like Spray and Akka throw errors when the fat JAR attempts to run. Errors look like:

Exception in thread "main" com.typesafe.config.ConfigException$Missing: No configuration setting found for key 'spray'
Exception in thread "main" com.typesafe.config.ConfigException$Missing: No configuration setting found for key 'akka'

推荐答案

最终的解决方法是将以下内容添加到build.gradle文件中:

The resulting fix was to add the following to the build.gradle file:

shadowJar {
  transform(com.github.jengelman.gradle.plugins.shadow.transformers.AppendingTransformer) {
    resource = 'reference.conf'
  }
}
