java - 为什么 maven 强制插件插件在 maven 版本 3.6.1 中失败但在 3.6.2 中通过？

问题描述

在我的一个项目中，我正在尝试将DependencyConvergence规则与 maven enforcer 插件一起使用。我观察到，如果我使用 Maven 3.6.1，那么执行器会因以下错误而失败，但同样适用于 maven 3.6.2。

有人可以让我知道 Maven 3.6.2 中导致DependencyConvergence通过 3.6.2 但在低于 3.6.2 的其他 maven 版本中失败的变化吗？

我在GitHub 上放置了一个示例项目，可以在其中重现此问题。

解决方案

它与Maven 3.6.2中修复的错误MANFORCER-195和MNG-6713有关。

如果您使用的是 3.6.2，请小心，因为该区域有进一步的回归，直到 3.6.3 才修复（不影响您的示例）。

我是如何找到这些票的：

让我们分别看一下每个故障。从第一个开始是有意义的：

Dependency convergence error for com.carrotsearch.randomizedtesting:randomizedtesting-runner:2.7.1 paths to dependency are:
+-org.example:dedup:1.0-SNAPSHOT
  +-org.elasticsearch.test:framework:7.7.1
    +-com.carrotsearch.randomizedtesting:randomizedtesting-runner:2.7.1
and
+-org.example:dedup:1.0-SNAPSHOT
  +-org.elasticsearch.test:framework:7.7.1
    +-org.apache.lucene:lucene-test-framework:8.5.1
      +-com.carrotsearch.randomizedtesting:randomizedtesting-runner:2.7.2

让我们看看org.elasticsearch.test:framework's POM的相关部分：

<dependency>
    <groupId>com.carrotsearch.randomizedtesting</groupId>
    <artifactId>randomizedtesting-runner</artifactId>
    <version>2.7.1</version>
    <scope>compile</scope>
    <exclusions>
        <exclusion>
            <artifactId>*</artifactId>
            <groupId>*</groupId>
        </exclusion>
    </exclusions>
</dependency>

<dependency>
    <groupId>org.apache.lucene</groupId>
    <artifactId>lucene-test-framework</artifactId>
    <version>8.5.1</version>
    <scope>compile</scope>
    <exclusions>
        <exclusion>
          <artifactId>*</artifactId>
          <groupId>*</groupId>
      </exclusion>
    </exclusions>
</dependency>

很明显，我们可以看到 Lucene 的所有传递依赖项都应该被排除。但是，如果我们回到错误的这一部分，2.7.2Enforcer 插件抱怨的版本甚至不应该在依赖关系树中！

...
   +-org.apache.lucene:lucene-test-framework:8.5.1
        +-com.carrotsearch.randomizedtesting:randomizedtesting-runner:2.7.2

当我为两个版本的 Maven（3.6.1 和 3.6.2）打印 Maven 依赖树时，randomizedtesting-runner我看到的唯一实例是2.7.1版本，所以这里发生了一些可疑的事情。

我的直觉告诉我，通配符排除可能是罪魁祸首，所以从那里只需在发行说明中搜索“排除”或“通配符”之类的东西。事实证明我是对的。
