我们使用Atlassian Jira war并自定义它，然后部署战争。 Ant是构建它的首选和建议方式。但Jenkins构建需要花费大量时间，我们希望使用更好的方法来进行依赖关系管理。我们使用apache archiva作为我们的存储库。
之前我曾计划获取jar校验和并构建POM然后自定义它。 https://github.com/myspotontheweb/ant2ivy/blob/master/ant2ivy.groovy
Getting a File's MD5 Checksum in Java
这种方法似乎有点容易出错，所以我现在决定直接从jar中读取pom.properties文件并使用mvn依赖获取detials：get plugin。
我的问题是： 如果我用jar读取并创建一个POM，它将是一个很长的依赖项条目列表。有没有更好的方法来处理它像一个具有父和子依赖关系的真实POM文件。我们想要这样做，每次构建/升级都会很难。或者只是一些更好的想法。

这就是我设法将所有依赖项从Ant lib文件夹转换为gradle格式构建脚本的方法。这里也没有其他方法..
