开发代码生成器时，需要打包成可执行文件

<build>
		<resources>
			<resource>
				<directory>src/main/java</directory>
				<includes>
					<include>**/*.png</include>
				</includes>
				<filtering>false</filtering>
			</resource>
		</resources>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-shade-plugin</artifactId>
				<version>1.2.1</version>
				<executions>
					<execution>
						<phase>package</phase>
						<goals>
							<goal>shade</goal>
						</goals>
						<configuration>
 							<shadedArtifactAttached>true</shadedArtifactAttached><!--这个会另外生成shade包 并导入的所有依赖-->
							<transformers>
								<transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
									<mainClass>*.*.MainCalss</mainClass><!--main方法所在类含包路径的类名-->
								</transformer>
							</transformers>
						</configuration>
					</execution>
				</executions>
			</plugin>

		<plugins>
		<resources>
		</build>

在执行可执行文件时，又出现了如下错误

Invalid signature file digest for Manifest main attributes

可以执行命令去掉包中的内容

zip -d yourjarname.jar META-INF/*.RSA META-INF/*.DSA META-INF/*.SF
