如何在pom.xml上运行maven-jdeps-插件？

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>

但是当我在JDK 8和maven 3.3.3中运行这个插件时，jdeps插件不做任何检查

$ mvn clean install -DskipTests | grep plugin

Answer 1

因为问题是用Java-9标记的。maven jdeps插件版本的3.1.0是正式的最近发布，也被称为与jdk9兼容。

官方的插件的使用页面也在@khmarbaise的评论中指出，实现如下：

<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

如果检测到内部API的任何使用情况，则生成将停止并失败。

可以使用failOnWarning标志进行配置，该标志的默认值设置为true。

正如Di Matteo在评论中所建议的那样，这个配置修复了它：

<build>
<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jdeps-plugin</artifactId>
    <version>3.0.0</version>
    <executions>
      <execution>
        <goals>
          <goal>jdkinternals</goal>
          <goal>test-jdkinternals</goal>
        </goals>
      </execution>
    </executions>
  </plugin>
</plugins>
</build>

<goals>直接在<plugin>下的使用是不赞成，不起作用，但不会很快失效。
