java - 为什么 maven 执行器插件在 maven 版本 3.6.1 时失败，但在 3.6.2 时通过？

标签 java maven java-8 maven-3

在我的一个项目中，我试图使用 DependencyConvergence使用 Maven 执行器插件进行规则。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，但在 Maven 3.6.2 中同样可以正常工作。
有人可以让我知道 Maven 3.6.2 中导致 DependencyConvergence 的更改吗？通过 3.6.2 但在其他低于 3.6.2 的 Maven 版本中失败？
我在 GitHub 上放置了一个示例项目哪里可以重现这个问题。

最佳答案

它与MENFORCER-195有关和 MNG-6713这是在 Maven 3.6.2 中修复的错误.
如果您使用的是 3.6.2，请小心，因为有 a further regression在这个区域直到 3.6.3 才被修复(不影响你的例子)。

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
我们来看 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在外。但是，如果我们回到这部分错误，2.7.2 Enforcer 插件提示的版本甚至不应该在依赖树中!
...
   +-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 的唯一实例我看到的是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，所以从那里开始只是搜索 the release notes 的问题。对于诸如“排除”或“通配符”之类的东西。原来我是对的。
