java – 父pom和微服务器

我与Maven一起工作的方式是拥有一个声明为父母的pom：

>通用依赖项(记录API,JUnit等).
>常用插件
> dependencyManagement部分的所有依赖关系.
> pluginManagement部分中的所有插件.

每个模块将父pom作为其父对象,但父对此模块无关.

这样做的好处来自上面的最后两颗子弹,“管理”部分.在“管理”部分中包含的任何内容需要在要使用特定依赖项或插件的模块中重新声明.

例如,父母可能看起来像这样：

<project>

  <groupId>com.example</groupId>
  <artifactId>parent</artifactId>
  <version>1.0.00-SNAPSHOT</version>

  ...

  <dependencies>

    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-api</artifactId>
      <version>1.7.7</version>
    </dependency>

    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.11</version>
      <scope>test</scope>
    </dependency>            

  </dependencies>

  <dependencyManagement>

    <dependency>
      <groupId>commons-lang</groupId>
      <artifactId>commons-lang</artifactId>
      <version>2.6</version>
    </dependency>        

    <dependency>
      <groupId>commons-collections</groupId>
      <artifactId>commons-collections</artifactId>
      <version>2.1</version>
    </dependency>

  </dependencyManagement>

  <plugins>

    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.1</version>
      <configuration>
        <source>1.8</source>
        <target>1.8</target>
      </configuration>
    </plugin>

  <plugins>

  <pluginManagement>

    <plugins>

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-assembly-plugin</artifactId>
        <version>2.4</version>
        <configuration>
          <appendAssemblyId>false</appendAssemblyId>
          <descriptors>
            <descriptor>src/main/assembly/assembly.xml</descriptor>
          </descriptors>
        </configuration>
        <executions>
          <execution>
            <id>make-assembly</id>
            <phase>package</phase>
            <goals>
              <goal>single</goal>
            </goals>
          </execution>
        </executions>
      </plugin>

    </plugins>

  </pluginManagement>

</project>

并且模块可能如下所示：

<project>

  <parent>
    <groupId>com.example</groupId>
    <artifactId>parent</artifactId>
    <version>1.0.00-SNAPSHOT</version>
  </parent>

  <groupId>com.example</groupId>
  <artifactId>module</artifactId>
  <version>1.0.00-SNAPSHOT</version>

  <dependencies>

    <dependency>
      <groupId>commons-lang</groupId>
      <artifactId>commons-lang</artifactId>          
    </dependency>        

  </dependencies>

  <plugins>

    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-assembly-plugin</artifactId>
    </plugin>

  </plugins>

</project>

该模块将：

>依赖于org.slf4j：slf4j-api：1.7.7：compile,junit：junit：4.11：test and commons-lang：commons-lang：2.6：compile.>有插件org.apache.maven.plugins：maven-assembly-plugin：2.4
