错误描述

org.apache.flink.client.program.ProgramInvocationException: The program's entry point class 'ods.DataCleaning' caused an exception during initialization: Invalid signature file digest for Manifest main attributes
        at org.apache.flink.client.program.PackagedProgram.loadMainClass(PackagedProgram.java:497)
        at org.apache.flink.client.cli.CliFrontend.main(CliFrontend.java:1132)
Caused by: java.lang.SecurityException: Invalid signature file digest for Manifest main attributes
        at sun.security.util.SignatureFileVerifier.processImpl(SignatureFileVerifier.java:330)

分析

因为依赖jar包中的 META-INF 中有多余的 .SF 文件与当前jar包冲突

解决

在 <version> 下增加下面代码：

<configuration>
    <filters>
        <filter>
            <artifact>*:*</artifact>
            <excludes>
                <exclude>META-INF/*.SF</exclude>
                <exclude>META-INF/*.DSA</exclude>
                <exclude>META-INF/*.RSA</exclude>
            </excludes>
        </filter>
    </filters>
</configuration>

例子：

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>2.2</version>
            <configuration>
                <filters>
                    <filter>
                        <artifact>*:*</artifact>
                        <excludes>
                            <exclude>META-INF/*.SF</exclude>
                            <exclude>META-INF/*.DSA</exclude>
                            <exclude>META-INF/*.RSA</exclude>
                        </excludes>
                    </filter>
                </filters>
            </configuration>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                    <configuration>
                        <transformers>
                            <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                <mainClass></mainClass>
                            </transformer>
                        </transformers>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
