maven打包将依赖和配置外置的配置方式

Posted 2021-03-02 Silentdoer

注意，如果是依赖了本地公用项目，需要将本地公用项目通过mvn install安装到本地maven仓库；

将项目依赖的jar包外置到主jar包所在目录的lib目录，resources文件外置到主jar包所在目录的配置：

<build>
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
            </resource>
        </resources>

        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>

                <configuration>
                    <archive>
                        <!-- 配置打包后jar包内的元数据，比如classpath是什么【从哪里找依赖】 -->
                        <manifest>
                            <addClasspath>true</addClasspath>
                            <classpathPrefix>lib/</classpathPrefix>
                            <mainClass>me.silentdoer.demomybladetest.Entrance</mainClass>

                        <manifestEntries>
