maven - p2-maven-plugin因hadoop失败

Question

如果我将hadoop-annotations作为(传递)依赖项包含在内，则使用mvn p2:site运行p2-maven-plugin会失败:

[info] Executing Bundler:
[info]   [EXEC] hadoop-common-2.7.1.jar

我怎样才能解决这个问题？

Answer 1

hadoop注释取决于JDK jar:

<dependency>
  <groupId>jdk.tools</groupId>
  <artifactId>jdk.tools</artifactId>
  <version>1.6</version>
  <scope>system</scope>
  <systemPath>${java.home}/../lib/tools.jar</systemPath>
</dependency>

您必须在p2-maven-plugin配置中排除此情况:

<artifact>
    <id>{artifact that depends on hadoop-annotations}</id>
    <excludes>
        <exclude>jdk.tools:jdk.tools</exclude> <!-- workaround for hadoop-annotations -->
    </excludes>
</artifact>
