我想排除谷歌收藏jar，即使使用了exclude标记，它也会被下载。这样，每当我执行"mvn-clean-install"时，就不应该下载google-collections.jar。
每当我执行mvn-clean-install-googlecollection-jar下载时，我仍然尝试在所有依赖项中添加exclude。
我还尝试从m2 repo手动删除jar文件，然后运行mvn clean install。它再次下载。

由于我已经排除了谷歌收藏，它的Jar不应该下载。
但它下载谷歌收藏罐。
我对尝试所有组合毫无头绪，也很沮丧。如果有人能解释为什么这不起作用，以及下载谷歌收藏罐的依赖关系，那就太好了。
我注释掉了对guava的依赖，并执行mvn干净安装。它下载谷歌收藏罐。
我检查了您的依赖项，并且您没有将google-collections作为依赖项。
但是，您有guava，它是google-collections的继任者。但是该依赖项是您作为最后一个依赖项明确请求的。
然而。。。如果我删除了您在pom.xml文件中添加的所有排除项，那么确实有一个依赖于google-collections的依赖项：它是maven-surefire-report-plugin(这是一个插件，不应该是依赖项)，但是。。。您准确地将google-collections从其自身的依赖项中排除！因此google-collections完全不存在。
你可以通过进入你的项目文件夹并键入：来检查这一点
mvn dependency:tree

如您所见，不存在间接依赖项名称google-collections。
因此，你很可能会考虑另一个问题，这会让你认为google-collections存在，我非常希望你说出为什么你认为google-collections存在，尽管它不存在，因为事实上，不存在任何问题。
第一次执行mvn clean install时，它会下载pom.xml中存在的所有依赖项，并将其存储在.m2存储库中。因此，现在当您使用exclude标记时，它不会有任何更改，因为提到的依赖项已经存在于您的m2存储库中。
因此，您需要从m2存储库中删除jar，为此，您需要转到m2存储库并手动删除该jar，现在如果您使用exclude标记并执行mvn clean install，它将不会再次下载。
要找到m2回购的路径，您可以查看：如何获取Maven本地回购位置？
