maven笔记

　　用了许久的maven，但仍然缺乏研究。

1、插件：在pom.xml中进行配置，可以在maven窗口中控制plugins的行为。

• assembly：可以连带着将所有依赖的jar都打包成一个大的jar包，在build下放置plugins。

      <plugins>
        <plugin>
          <artifactId>maven-assembly-plugin</artifactId>
          <version>2.6</version>
          <configuration>
            <!-- get all project dependencies -->
            <descriptorRefs>
              <descriptorRef>jar-with-dependencies</descriptorRef>
            </descriptorRefs>
            <!-- MainClass in mainfest make a executable jar -->
            <archive>
              <manifest>
                <mainClass>App.main</mainClass>
              </manifest>
            </archive>
          </configuration>
          <executions>
            <execution>
              <id>make-assembly</id>
              <!-- bind to the packaging phase -->
              <phase>package</phase>
              <goals>
                <goal>single</goal>
              </goals>
            </execution>
          </executions>
        </plugin>
      </plugins>

• deploy：将打好的jar包发布到maven私服(Lifecycle下的deploy进行执行)：注意plugins和plugManagement的区别
  • 配置pom文件

      <distributionManagement>
        <repository>
          <id>reponame-nexus-release</id>
          <url>
            http://remoteSrv/nexus/repository/reponame/
          </url>
        </repository>
        <snapshotRepository>
          <id>reponame-nexus-snapshot</id>
          <url>
            http://remoteSrv/nexus/repository/reponame/
          </url>
        </snapshotRepository>
      </distributionManagement>

  • 配置~/.m2/settings.xml文件

      <servers>
        <server>
          <id>reponame-nexus-snapshot</id>
            <username>user.can.upload</username>
            <password>password</password>
        </server>
        <server>
          <id>reponame-nexus-release</id>
            <username>user.can.upload</username>
            <password>password</password>
        </server>
      </servers>
