问题描述

我正在研究的项目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 将源和目标替换为发布:

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

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?有任何解决这个问题的方法吗?


如果可能有帮助,此目标的调试日志如下:

使用复制:

  1. Git 签出这个分支
  2. 配置 Maven 以使用 Java-17。
  3. failOnWarning将属性编辑为true
  4. 执行mvn clean verify

解决方案


经过调查,我发现问题出在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新属性进行分析: testArtifactsWithNonTestScope您可以比较以下代码截图: 版本 3.1.2:

在此处输入图像描述

版本 3.2.0: 在此处输入图像描述

我在插件中调试了完整的分析器依赖过程,发现依赖:

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

被传递给testArtifactsWithNonTestScope一组工件,因为类org.hamcrest.MatcherAssert仅在测试类中使用。当然,这种行为是不正确的,因为依赖的其他类hamcrest存在于非测试类中 - 肯定存在maven-dependency-plugin.

附言

就像我的想法的证明一样,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,我添加了使用org.hamcrest.MatcherAssertin的新方法Java8Matchers,之后构建过程将成功完成。


经过以上所有方面,您有以下方法可以解决问题:

  • 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
  • 为构建关闭分析器并等待分析器的修复
