使用meaven打包过程中遇到的一些问题

使用maven-shade-plugin插件，修改后pom代码如下

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>1.4</version>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>shade</goal>
            </goals>
            <configuration>
                <transformers>
                    <transformer
                        implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                        <resource>META-INF/spring.handlers</resource>
                    </transformer>
                    <transformer
                        implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                        <mainClass>com.fxc.rpc.impl.member.MemberProvider</mainClass>
                    </transformer>
                    <transformer
                        implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                        <resource>META-INF/spring.schemas</resource>
                    </transformer>
                </transformers>
            </configuration>
        </execution>
    </executions>
</plugin>

再次打包，出现文件签名不合法的问题

Exception in thread "main" java.lang.SecurityException: Invalid signature file digest for Manifest main attributes

再查，原来是由于某些包的重复引用，以至于打包之后的META-INF的目录下多出了一些*.SF,*.DSA,*.RSA文件所致（据说解压jar包，然后删掉这些文件再次打包错误就会消失，未确认），再次修改pom.xml，最终使用如下配置文件，运行

mvn clean install -Dmaven.test.skip=true

打包成功
