1、項目所依賴的jar是沒有中心倉庫,比如阿里私服也沒有,這樣的jar有2中處理方式:
1)自己搭建nexus私服,並把該jar同步上去
2)在項目pom.xml配置:
<dependency>
<groupId>com.nz</groupId>
<artifactId>dubbo-api</artifactId>
<version>1.0</version>
<scope>system</scope>
<systemPath>${project.basedir}/lib/dubbo-api-1.0.jar</systemPath>
<!-- 本地沒有私服,要配置systemPath,並在下面的plugin指定manifestEntries -->
</dependency>
2、maven打包項目成jar時,要配置plugins
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.10</version>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
<!-- jar打包相關插件 -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<addDefaultImplementationEntries>true</addDefaultImplementationEntries>
<mainClass>org.dubbo.server.App</mainClass>
</manifest>
<!-- 添加classpath缺少的內容-->
<manifestEntries>
<Class-Path>lib/dubbo-api-1.0.jar</Class-Path>
</manifestEntries>
</archive>
</configuration>
</plugin>
3、這樣打包的jar的META-INF/MANIFEST.MF文件有兩個注意點:
Class-Path:其依賴的所有jar
Main-Class:java運行的主程序
