maven-surefire-plugin ignores plugins order in pom.xml

问题

I have multimodule maven project. This project contains self written maven plugin and test project for this plugin. I want to run my plugin in test phase before maven-surefire-plugin I put maven-surefire-plugin after my plugin in pom.xml

<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>

But maven-surefire-plugin still runs first.

Is it expected behavior for maven-surefire-plugin? How to change order of plugins execution?

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.

the trick here is, to first bind your plugin (in my antrun) to the test phase, and after this, unbind the "default-test" phase. after this you can bind the maven-surfire to the test phase again.
