同时使用 maven-flatten-plugin 和 maven-shade-plugin [英] Use maven-flatten-plugin and maven-shade-plugin at the same time
问题描述
如何同时使用maven-flatten-plugin和maven-shade-plugin?
How to use the maven-flatten-plugin and maven-shade-plugin at the same time?
我使用 revision,sha1,changelist 来管理多模块项目的版本.
I use revision,sha1,changelist to manage the versions of a multi-module project.
为了部署 cosumable artifacts，我使用 maven-flatten-plugin 生成一个扁平的 pom，使 ${revision} 具有实际价值.
In order to deploy cosumable artifacts, I use maven-flatten-plugin to generate a flattened pom which make ${revision} to real value.
但是 maven-shade-plugin 在 ${revision} 不变的情况下产生了一个减少的 pom.
But the maven-shade-plugin produces a reduced pom with ${revision} unchanged.
如何指定maven-shade-plugin使用flattened pom来减少pom.
How to specify the maven-shade-plugin to use the flattened pom to reduce the pom.
推荐答案
我今天遇到了同样的问题，但我在网上找不到真正的解决方案.虽然 PaulT 的建议可能对某些人有用，但我发现这是不可接受的，因为尽管将 true，但生成的 pom 中仍未包含传递依赖项.
I experienced this same issue today and I found no real solution on the web. While PaulT's suggestion might work for some, I found this unacceptable since the transitive dependencies were still not being included in the generated pom despite the setting of <promoteTransitiveDependencies> to true.
我可以通过简单地改变 flatten 和 shade 之间的执行顺序来解决这个问题.您只需要确保 flatten 运行 AFTER shade.如果您在父 pom 中定义了 flatten 插件，只需在您的聚合器项目中添加相同的插件定义，并使用相同的执行 ID.
I was able to fix this by simply changing the order of execution between flatten and shade. You just need to make sure that flatten runs AFTER shade. If you have defined the flatten plugin in your parent pom, simply add the same plugin definition on your aggregator project with the same execution id.
