我很难配置我的pom.xml来做我想做的事。
我想将我的项目打包为一个可执行的jar文件。
这是我使用的命令:
我当前的pom.xml完成了工作,目标文件夹中生成的jar文件确实是可执行的,但是如果我列出其中的文件,则有4202个文件(我的helo world +来自scala语言的4201个文件)。
这是正常的吗?是不是有办法用scala-library.jar构建我的jar?怎么样?

答案 0 :(得分:1)
是的,这是正常的。
如果你在jar中包含scala-library.jar作为jar,那么你应该包含一个自定义代码加载到你的main(...)中。
java -jar xxx.jar
忽略jar里面的jar
<unpack>false</unpack>
创建自己的程序集描述文件(在二进制文件或root下,我不记得了)+更改main以从Resource加载jar(你的main()
应注意取决于scala-library)但我的建议是,使用Proguard:它会像你当前的代码一样创建一个jar,但它会缩小无用的代码(scala-library的很多部分)。手动尝试(首先没有maven-plugin)通过gui找到你正确的配置,它可能需要时间(如果你使用反射,......)。
