java - 将 Jersey 从 1.x 迁移到 2.x 时出现编译错误

Question

我的 pom 文件包含:

<dependency>
  <groupId>org.glassfish.jersey.core</groupId>
  <artifactId>jersey-client</artifactId>
  <version>2.22.1</version>
</dependency>
<dependency>
  <groupId>org.glassfish.jersey.core</groupId>
  <artifactId>jersey-server</artifactId>
  <version>2.22.1</version>
</dependency>
<dependency>
  <groupId>org.glassfish.jersey.core</groupId>
  <artifactId>jersey-common</artifactId>
  <version>2.22.1</version>
</dependency>
<dependency>
  <groupId>org.glassfish.jersey.media</groupId>
  <artifactId>jersey-media-json-jettison</artifactId>
  <version>2.21.1</version>
</dependency>

日志中显示的错误:更新错误:

更新:删除上述依赖项后，我成功构建了我的项目。所以看起来上述之一需要其他依赖项。有什么想法吗？

更新 1:这就是分析的定义方式

      <execution>
        <phase>package</phase>
        <goals>
          <goal>analyse</goal>
        </goals>
      </execution>

Answer 1

所以我们确实有一个分析 pom 的目标(我们将它放在父 pom 上)。这个分析只是确保我们不会在 sons pom.xml 中声明重复的东西。一旦我删除了重复项，一切就都构建好了。顺便说一句:通过删除这个目标，我也将获得成功。
