META-INF中的Maven pom.xml与Maven存储库中的pom.xml

[英]Maven pom.xml in META-INF vs pom.xml in Maven repository

原文 2018-11-06 15:00:56 6 1 java/ maven/ bazel

I'm trying to produce a Maven-compatible artefact using bazel . 我正在尝试使用bazel生成与Maven兼容的人工制品。 I noticed that mvn puts some files inside META-INF directory in JAR archive ( file.jar/META-INF/maven/groupId/artifactId/pom.xml and file.jar/META-INF/maven/groupId/artifactId/pom.properties ) 我注意到mvn将一些文件放在JAR存档中的META-INF目录中（ file.jar/META-INF/maven/groupId/artifactId/pom.xml和file.jar/META-INF/maven/groupId/artifactId/pom.properties ）

Questions: 问题：

Are they needed to be able to successfully depend on my artifact from another project? 他们是否需要能够成功地依赖我的另一个项目的工件？ I know you can disable them via a config option in pom.xml ref , which leads me to believe that you don't. 我知道你可以通过pom.xml ref中的配置选项禁用它们，这让我相信你没有。
Are they used by mvn in any case whatsoever? 在任何情况下， mvn都使用它们吗？
Can I use pom.xml inside on the JAR instead of pom.xml near my artifact in Maven repo? 我可以用pom.xml在瓶子内 ，而不是 pom.xml靠近我在Maven的回购神器？

We have several jars in your Maven repository that do not contain a pom.xml. 我们在Maven存储库中有几个不包含pom.xml的jar。 For maven, the revelant pom.xml is the one that is outside your artifact. 对于maven，重要的pom.xml是你工件之外的那个。 In Nexus, you deploy a jar always along with a pom.xml and that is the one that counts. 在Nexus中，您总是将一个jar与pom.xml一起部署，这就是重要的一个。

So you need to publish a pom.xml along with your jar if you want to use it from Maven, but you do not need to put it inside. 因此，如果要从Maven中使用它，则需要与jar一起发布pom.xml，但不需要将其放入其中。 AFAIK you cannot change this behaviour. AFAIK你无法改变这种行为。
