java - 如何在 pom.xml 上运行 maven-jdeps-plugin？

Question

在我的 pom.xml 中，我添加了 maven-jdeps-plugin:

<project ...>
  <groupId>org.optaplanner</groupId>
  <artifactId>optaplanner-examples</artifactId>
  <!-- packaging is the default, so "jar" -->
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jdeps-plugin</artifactId>
        <version>3.0.0</version>
        <goals>
          <goal>jdkinternals</goal>
          <goal>test-jdkinternals</goal>
        </goals>
      </plugin>
    </plugins>
  </build>
</project>

但是当我使用 JDK 8 和 maven 3.3.3 运行它时，jdeps 插件不做任何检查:

Answer 1

因为问题是用 Java-9 标记的。 maven jdeps plugin版本 3.1.0 正式 released recently并声称是 compatible with jdk9

官方usage page of the plugin正如@khmarbaise 在评论中指出的那样，将实现方式描述为:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jdeps-plugin</artifactId>
    <version>3.1.0</version>
    <executions>
      <execution>
        <goals>
          <goal>jdkinternals</goal> <!-- verify main classes -->
          <goal>test-jdkinternals</goal> <!-- verify test classes -->
        </goals>
      </execution>
    </executions>
    <configuration>
      ...
    </configuration>
</plugin>

其中

If there is any usage detected of an internal API, the build will stop and fail.

可以使用标志配置 failOnWarning它的默认值设置为 true。
