Question

跟进this问题：在不冲突的情况下，我无法找到有关如何构建多个（活动）maven配置文件的联合信息。

考虑以下示例：我想控制我的测试用例如何使用maven-surefire-plugin运行。首先，我需要配置两个不同的环境（jenkins-CI-server）和本地环境。其次，我想启用运行不同的测试集。我会有四个档案：

env_jenkins在jenkins上运行
env_local在本地
testset_A用于运行某些测试
testset_B用于运行其他一些测试

请注意，对于所有这些配置文件，我需要为maven-surefire-plugin定义插件配置。（具体的xml配置见下文）

然后我想组合配置文件来运行 - 例如 - jenkins上的testset A.

我的问题：

maven是否支持这种行为？
the related question中提及的覆盖在哪个阶段发生？是否覆盖了整个插件配置（ - ＆gt;我的示例不起作用）。或者只是真正有冲突的部分（ - ＆gt;我的例子会起作用）？
覆盖行为是否取决于插件，还是所有maven插件都一致？

示例pom：

    <profile>

Answer 1

它使用在父POM和子POM之间工作的相同inheritance/merging process。使用Maven帮助插件可以确认这一点（使用Maven 3.3.9）：

POM中的个人资料声明顺序很重要。插件配置继承了在POM中出现的活动配置文件中声明的相同插件配置。
属性combine.self和combine.children可用于控制合并。

使用默认设置的示例（不使用combine.self或combine.children，即隐式使用combine.children="merge"）：

mvn help:effective-pom -Penv_local,testset_A

有效POM显示合并配置：

...
<plugin>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.12.4</version>
    <executions>
      <execution>
        <id>default-test</id>
        <phase>test</phase>
        <goals>
          <goal>test</goal>
        </goals>
        <configuration>
          <includes>
            <include>TestA1.java</include>
            <include>TestA2.java</include>
            <include>TestA3.java</include>
          </includes>
          <systemPropertyVariables>
            <arquillian.launch>jbossas-managed-jenkins</arquillian.launch>
            <jbossHttpPortOverride>${jboss.http.port}</jbossHttpPortOverride>
          </systemPropertyVariables>
        </configuration>
      </execution>
    </executions>
    <configuration>
      <includes>
        <include>TestA1.java</include>
        <include>TestA2.java</include>
        <include>TestA3.java</include>
      </includes>
      <systemPropertyVariables>
        <arquillian.launch>jbossas-managed-jenkins</arquillian.launch>
        <jbossHttpPortOverride>${jboss.http.port}</jbossHttpPortOverride>
      </systemPropertyVariables>
    </configuration>
  </plugin>
  ...

combine.self="override"的示例：

<profile>
    <id>testset_A</id>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <configuration combine.self="override">
                    <includes>
                        <include>TestA1.java</include>
                        <include>TestA2.java</include>
                        <include>TestA3.java</include>
                    </includes>
                </configuration>
            </plugin>
        </plugins>
    </build>
</profile>

mvn help:effective-pom -Penv_local,testset_A

有效POM仅显示testset_A的配置：

<plugin>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.12.4</version>
    <executions>
      <execution>
        <id>default-test</id>
        <phase>test</phase>
        <goals>
          <goal>test</goal>
        </goals>
        <configuration combine.self="override">
          <includes>
            <include>TestA1.java</include>
            <include>TestA2.java</include>
            <include>TestA3.java</include>
          </includes>
        </configuration>
      </execution>
    </executions>
    <configuration combine.self="override">
      <includes>
        <include>TestA1.java</include>
        <include>TestA2.java</include>
        <include>TestA3.java</include>
      </includes>
    </configuration>
  </plugin>

combine.children="append"的示例：

<profile>
    <id>testset_A</id>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <configuration combine.children="append">
                    <includes>
                        <include>TestA1.java</include>
                        <include>TestA2.java</include>
                        <include>TestA3.java</include>
                    </includes>
                </configuration>
            </plugin>
        </plugins>
    </build>
</profile>

mvn help:effective-pom -Penv_local,testset_A

有效POM显示合并配置。在这种情况下，它恰好与第一个示例相同。但是，如果testset_A引入了env_local中已存在的配置XML元素，则会附加它们：

<plugin>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.12.4</version>
    <executions>
      <execution>
        <id>default-test</id>
        <phase>test</phase>
        <goals>
          <goal>test</goal>
        </goals>
        <configuration combine.children="append">
          <systemPropertyVariables>
            <arquillian.launch>jbossas-managed-jenkins</arquillian.launch>
            <jbossHttpPortOverride>${jboss.http.port}</jbossHttpPortOverride>
          </systemPropertyVariables>
          <includes>
            <include>TestA1.java</include>
            <include>TestA2.java</include>
            <include>TestA3.java</include>
          </includes>
        </configuration>
      </execution>
    </executions>
    <configuration combine.children="append">
      <systemPropertyVariables>
        <arquillian.launch>jbossas-managed-jenkins</arquillian.launch>
        <jbossHttpPortOverride>${jboss.http.port}</jbossHttpPortOverride>
      </systemPropertyVariables>
      <includes>
        <include>TestA1.java</include>
        <include>TestA2.java</include>
        <include>TestA3.java</include>
      </includes>
    </configuration>
  </plugin>

如果激活多个配置文件，如何解决非冲突配置？
