是否可以覆盖已经为父POM中的配置文件定义的插件的配置? [英] Is it possible to override the configuration of a plugin already defined for a profile in a parent POM?

问题描述

在我的项目的POM父文件中，我有一个配置文件，定义了一些对该项目有用的配置(以使我无法摆脱该父POM):

In a POM parent file of my project, I have such a profile defining some configurations useful for this project (so that I can't get rid of this parent POM) :

<profile>
<id>wls7</id>
...
<build>
  <plugins>
    <!-- use java 1.4 -->
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <configuration>
        <fork>true</fork>
        <source>1.4</source>
        <target>1.4</target>
        <meminitial>128m</meminitial>
        <maxmem>1024m</maxmem>
        <executable>%${jdk14.executable}</executable>
      </configuration>
    </plugin>
  </plugins>
</build>

...
</profile>

但是在我的项目中，我只是想覆盖maven-compiler-plugin的配置，以便使用jdk5而不是jdk4来编译测试类.

But in my project I just would like to override the configuration of the maven-compiler-plugin in order to use jdk5 instead of jdk4 for compiling test-classes.

这就是为什么我在项目的POM中执行此部分的原因:

That's why I did this section in the POM of my project :

<profiles>
  <profile>
    <id>wls7</id>
        <activation>
            <property>
                <name>jdk</name>
                <value>4</value>
            </property>
        </activation>
    <build>
      <directory>target-1.4</directory>
      <plugins>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-compiler-plugin</artifactId>
          <executions>
            <execution>
              <id>my-testCompile</id>
              <phase>test-compile</phase>
              <goals>
                <goal>testCompile</goal>
              </goals>
              <configuration>
                <fork>true</fork>
                <executable>${jdk15.executable}</executable>
                <compilerVersion>1.5</compilerVersion>
                <source>1.5</source>
                <target>1.5</target>
                <verbose>true</verbose>
              </configuration>
            </execution>
          </executions>
        </plugin>
      </plugins>
    </build>
  </profile>
              ...
</profiles>

它不起作用...

我什至试图覆盖POM常规插件部分中的配置(我的意思是，不是针对特定配置文件，而是针对整个POM).

I even tried to override the configuration in regular plugin sections of my POM (I mean, not for a specific profile but for my whole POM).

可能是什么问题?

要阐明我的一些要求:

• 我不想摆脱父母 POM和定义的配置文件(wls7) 里面(因为我需要很多 属性，配置...)和 那不是我的过程 公司.
• 基于复制的解决方案 父POM和/或配置文件 里面定义不好 一.因为如果负责
  父POM有所更改，我
  将不得不在我的报告.

• I don't want to get rid of the parent POM and the profile (wls7) defined inside it (since I need many and many properties, configurations, ...) and that is not the process in my company.
• A solution based on duplicating the parent POM and/or the profile defined inside it is not a good one. Since if the responsible of
  the parent POM change something, I
  would have to report it in mine.

这只是一个继承问题(扩展或覆盖配置文件，即来自上层POM的配置)，所以我认为Maven 2应该可以做到这一点.

It's just an inheritance matter (extend or override a profile, a configuration from an upper-level POM) so I think it should be possible with Maven 2.

推荐答案

可以通过将combine.self="override"属性添加到pom中的元素来完成从父pom覆盖配置.

Overriding configurations from a parent pom can be done by adding the combine.self="override" attribute to the element in your pom.

尝试将插件配置更改为:

Try changing your plugin configuration to:

    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <executions>
        <execution>
          <id>my-testCompile</id>
          <phase>test-compile</phase>
          <goals>
            <goal>testCompile</goal>
          </goals>
          <configuration combine.self="override">
            <fork>true</fork>
            <executable>${jdk15.executable}</executable>
            <compilerVersion>1.5</compilerVersion>
            <source>1.5</source>
            <target>1.5</target>
            <verbose>true</verbose>
          </configuration>
        </execution>
      </executions>
    </plugin>
