从生成的jar文件中排除META-INF/maven文件夹

问题描述

我正在尝试创建一个jar文件，其中提取了jar中所有必需的类.但是对于像 log4j 这样的一些依赖jar，它会在META-INF/maven/*内创建一些文件夹.我有一个限制，即将放置生成的jar文件的服务器将无法连接Internet.因此，如果此META-INF/maven/*文件夹中有任何内容，那么它将给我一个错误.

I am trying to create a jar file which has all the necessary classes extracted within the jar. But for few dependent jar like log4j, it creates some folders inside META-INF/maven/*. I have a limitation that the server in which I will be placing the generated jar file will not have Internet connectivity. So if there is any content in this META-INF/maven/* folder then it gives me an error.

我的maven描述符如下所示

My maven descriptor looks like the following

<build>
    <sourceDirectory>src</sourceDirectory>
    <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.3</version>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <configuration>
                <archive>
                    <addMavenDescriptor>false</addMavenDescriptor>
                </archive>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <minimizeJar>true</minimizeJar>
                <finalName>myclient</finalName>
            </configuration>
        </plugin>
    </plugins>
</build>

我能够在生成的jar中提取所需的类文件，但是在META-INF下仍会生成maven文件夹.我必须手动删除文件夹才能使所有工作正常.请提供有关如何自动从生成的jar文件中删除Maven文件夹的建议.

I am able to extract the required class files in the generated jar but the maven folder is still getting generated under META-INF. I have to manually delete the folder to make everything work. Please advice on how to automate this removal of maven folder from the generated jar file.

推荐答案

您可以使用过滤器，以排除每个工件META-INF/maven下的所有内容:

You can use filters inside the maven-shade-plugin configuration to exclude everything that is under META-INF/maven for every artifact:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>2.4.1</version>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>shade</goal>
            </goals>
            <configuration>
                <filters>
                    <filter>
                        <artifact>*:*</artifact>
                        <excludes>
                            <exclude>META-INF/maven/**</exclude>
                        </excludes>
                    </filter>
                </filters>
            </configuration>
        </execution>
    </executions>
</plugin>
