maven-surefire-plugin 忽略 pom.xml 中的插件顺序

Question

我有一个多模块 Maven 项目。该项目包含自己编写的 maven 插件和该插件的测试项目。 我想在 maven-surefire-plugin 之前的 test 阶段运行我的插件 我在 pom.xml 中的插件之后放置了 maven-surefire-plugin

<build>
    <plugins>
        <plugin>
            <groupId>com.my.group</groupId>
            <artifactId>validator-maven-plugin</artifactId>
            <version>${project.version}</version>
            <executions>
                <execution>
                    <phase>test</phase>
                    <goals>
                        <goal>validate</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
        <plugin>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.18.1</version>
            <executions>
                <execution>
                    <phase>test</phase>
                    <goals>
                        <goal>test</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
</build>

但是 maven-surefire-plugin 仍然先运行。

这是 maven-surefire-plugin 的预期行为吗？ 如何更改插件的执行顺序？

和控制台输出:

Some problems were encountered while building the effective model for ch.stefanheimberg.stackoverflow:stackoverflow-31225404:jar:1.0-SNAPSHOT
'build.plugins.plugin.version' for org.apache.maven.plugins:maven-surefire-plugin is missing. @ line 31, column 21

It is highly recommended to fix these problems because they threaten the stability of your build.

For this reason, future Maven versions might no longer support building such malformed projects.

这里的技巧是，首先将您的插件(在我的 antrun 中)绑定(bind)到测试阶段，然后再解除绑定(bind)“默认测试”阶段。在此之后，您可以再次将 maven-surfire 绑定(bind)到测试阶段。
