17 版在分析时“未找到依赖关系”

问题描述

我正在研究的 the project 之一具有以下相关配置:

<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>

<plugin>
    <artifactId>maven-dependency-plugin</artifactId>
    <version>3.2.0</version>
    <configuration>
        <failOnWarning>true</failOnWarning>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>analyze-only</goal>
            </goals>
        </execution>
    </executions>
</plugin>


<dependency>
    <groupId>org.hamcrest</groupId>
    <artifactId>hamcrest</artifactId>
    <version>2.2</version>
    <!-- not scoped to test -->
</dependency>

在执行 mvn clean verify (apache-maven-3.6.3,java : 17-ea) 时,构建按预期成功。我现在对属性进行了更改,以替换源和目标发布为:

<maven.compiler.release>17</maven.compiler.release>

和终端上的日志读取

[INFO] --- maven-dependency-plugin:3.2.0:analyze-only (default) @ java-8-matchers ---
[WARNING] Non-test scoped test only dependencies found:
[WARNING]    org.hamcrest:hamcrest:jar:2.2:compile

导致失败(因为警告)!为什么/如何在 Java 版本的升级中对依赖项进行不同的处理?有什么办法可以解决这个问题?


如果它可能有帮助,此目标的调试日志如下:

复制使用:

  1. Git 结帐 this branch
  2. 将 maven 配置为使用 Java-17。
  3. failOnWarning 属性修改true
  4. 执行mvn clean verify

解决方法

经过调查,我发现问题出在将 maven-dependency-plugin 从版本 3.1.2 升级到 3.2.0,因为在新版本的插件中添加了用于分析的新属性:testArtifactsWithNonTestScope 您可以比较屏幕截图下面的代码: 3.1.2 版:

enter image description here

3.2.0 版: enter image description here

我在插件中调试了完整的分析器依赖过程,发现了依赖:

<dependency>
   <groupId>org.hamcrest</groupId>
   <artifactId>hamcrest</artifactId>
   <version>2.2</version>
</dependency>

传递给 testArtifactsWithNonTestScope 组工件,因为类 org.hamcrest.MatcherAssert 仅用于测试类。当然,这种行为是不正确的,因为 hamcrest 依赖项中的其他类存在于非测试类中 - maven-dependency-plugin 中肯定存在缺陷。

附言

就像我的想法证明一样,您可以通过以下方式更改非测试类之一:

...
import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.Matchers.is;
...

public final class Java8Matchers {

    public static void customAssert(String reason,boolean assertion) {
        assertThat(reason,assertion);
    }
    
    ...
}

如您所见,我在 org.hamcrest.MatcherAssert 中添加了使用 Java8Matchers 的新方法,之后构建过程将成功完成。


综上所述,您可以通过以下方式解决问题:

  • 使用插件 3.1.2 支持的最新版本的 java,并且在错误修复之前不要更新插件
  • 关闭构建分析器并等待分析器修复
,

这个问题与Java版本无关,Java 16也失败了,我看来是maven-dependency-plugin被dependabot从3.1.2升级到3.2.0时出现的,降级解决了问题。
