scala - 如何在 sbt 中排除 META-INF/*.RSA', 'META-INF/*.SF' ,'META-INF/*.DSA'

Question

我已经从 Intellij 为 Spark+ scala 代码创建了 jar 并尝试在开发集群中运行该 jar，但最终出现以下错误:

您能否告知如何排除 META-INF 详细信息？

谢谢。

Answer 1

您将需要添加 maven-shade 插件并使用 excludes，如下所示:

 <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
           ..
          <filters>
            <filter>
              <artifact>*:*</artifact>
              <excludes>
                <exclude>META-INF/*.SF</exclude>
                <exclude>META-INF/*.DSA</exclude>
                <exclude>META-INF/*.RSA</exclude>
              </excludes>
            </filter>
          </filters>

这将删除签名文件并解决您的问题。
