maven 中如果一个module以来另一个模块的test class，需要使用maven-jar-plugin和classifier（最新的用type代替了）

1.项目a（被b以来的test class）

<project>
  <build>
    <plugins>
     <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-jar-plugin</artifactId>
       <version>2.4</version>
       <executions>
         <execution>
           <goals>
             <goal>test-jar</goal>
           </goals>
         </execution>
       </executions>
     </plugin>
    </plugins>
  </build>
</project>

2.项目b，以来a中的test calss

<project>
  ...
  <dependencies>
    <dependency>
      <groupId>com.myco.app</groupId>
      <artifactId>foo</artifactId>
      <version>1.0-SNAPSHOT</version>
      <type>test-jar</type>
      <scope>test</scope>
    </dependency>
  </dependencies>
  ...
</project> 

gradle项目越来越多，但是公司项目只能用maven，转换方法如下

1.每个项目的build.gradle(或者gradle.kts)加入插件

groovy:

plugins {
    id 'maven'
}

kotlin

plugins {
    maven
}

2.加入task

groovy

task writeNewPom {
    doLast {
        pom {
            project {
                inceptionYear '2008'
                licenses {
                    license {
                        name 'The Apache Software License, Version 2.0'
                        url 'http://www.apache.org/licenses/LICENSE-2.0.txt'
                        distribution 'repo'
                    }
                }
            }
        }.writeTo("$buildDir/newpom.xml")
    }
}

kotlin

task("writeNewPom") {
    doLast {
        maven.pom {
            withGroovyBuilder {
                "project" {
                    setProperty("inceptionYear", "2008")
                    "licenses" {
                        "license" {
                            setProperty("name", "The Apache Software License, Version 2.0")
                            setProperty("url", "http://www.apache.org/licenses/LICENSE-2.0.txt")
                            setProperty("distribution", "repo")
                        }
                    }
                }
            }
        }.writeTo("$buildDir/newpom.xml")
    }
}

3.gradle writeNewPom 运行即可
