java - 如何执行此 pom.xml 文件中的 3 次执行？

Question

当我执行mvn clean install. 我知道他们在 PluginManagement 部分，我觉得这是问题的一部分。谢谢

您还需要在配置文件的部分中引用插件plugins（目前您只有在maven-compiler-plugin那里引用），而不仅仅是在该pluginManagement部分中。

所以你的 pom 将是：

...
<profiles>
    <profile>
        <id>testing</id>
        <activation>
            <property>
                <name>!skipTests</name>
            </property>
        </activation>

        <build>
            <pluginManagement>
                <plugins>
                    <plugin>
                        <groupId>org.codehaus.mojo</groupId>
                        <artifactId>hibernate3-maven-plugin</artifactId>
                        <!-- excluded the configuration to keep this as short as possible -->
                        ...
                    </plugin>
                    <plugin>
                        <groupId>org.codehaus.mojo</groupId>
                        <artifactId>sql-maven-plugin</artifactId>
                        <!-- etc -->
                    </plugin>
                </plugins>
            </pluginManagement>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>
                    ...
                </plugin>
                <!-- add hibernate3-maven-plugin here. Don't need to   -->
                <!-- define a version or configuration as that has     -->
                <!-- already been done in the pluginManagement section -->
                <plugin>
                    <groupId>org.codehaus.mojo</groupId>
                    <artifactId>hibernate3-maven-plugin</artifactId>
                </plugin>
                <!-- am presuming you would also want the sql-maven-plugin to run -->
                <!-- so you would need to add it here as well                     -->
                <plugin>
                    <groupId>org.codehaus.mojo</groupId>
                    <artifactId>sql-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>
    </profile>
</profiles>

    ...

POM（和配置文件）的标准plugins部分定义了在构建期间应该执行哪些插件（以及如何基于它们的配置）。

该pluginManagement部分还plugin以几乎相同的方式包含元素，除了不是plugin为这个特定的项目构建配置信息之外，它旨在配置从该项目构建继承的项目构建（它也可用于配置当前的 pom）。但是，这只配置了在子元素中plugin实际引用的 s plugins（或当前 pom - 这是您的情况所缺少的）。孩子们有权推翻pluginManagement定义。

所以通常你会使用该pluginManagement部分来定义插件的标准配置，然后通过在 pom 的标准plugins部分中引用插件在子 pom 中激活它（并根据需要覆盖任何配置）。

可以在这里找到关于 POM 的 Maven 文档：http ://maven.apache.org/pom.html （可以比我解释得更好）
