maven - 如果指定了 "-DskipTests"或 "-Dmaven.test.skip=true"，如何跳过 Maven 插件执行？

Question

我正在使用 Maven 3.0.3。我有这个插件，通常我想在执行 JUnit 测试之前运行它:

    <profile>
        <id>dev</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <properties>
            <test.mysql.db.user>sbjunituser</test.mysql.db.user>
            <test.mysql.db.password></test.mysql.db.password>
            <test.mysql.db.prefix>sbjunit</test.mysql.db.prefix>
            <test.mysql.db.sid>${test.mysql.db.prefix}_${project.artifactId}</test.mysql.db.sid>
            <test.mysql.db.host>localhost</test.mysql.db.host>
            <test.mysql.db.port>3306</test.mysql.db.port>
            <test.mysql.dataSource.url>jdbc:mysql://${test.mysql.db.host}:${test.mysql.db.port}/${test.mysql.db.sid}</test.mysql.dataSource.url>
            <test.mysql.dataSource.driverClassName>com.mysql.jdbc.Driver</test.mysql.dataSource.driverClassName>
        </properties>
        <build>
            <plugins>
        <!--  Run the liquibase scripts -->
        <plugin>
            <groupId>org.liquibase</groupId>
            <artifactId>liquibase-maven-plugin</artifactId>
            <version>2.0.1</version>
            <dependencies>
                <dependency>
                    <groupId>mysql</groupId>
                    <artifactId>mysql-connector-java</artifactId>
                    <version>5.1.18</version>
                </dependency>
            </dependencies>
            <executions>
                <execution>
                    <id>build-database</id>
                    <phase>process-test-classes</phase>
                    <configuration>
                        <driver>com.mysql.jdbc.Driver</driver>
                        <url>jdbc:mysql://${test.mysql.db.host}:${test.mysql.db.port}/${test.mysql.db.sid}</url>
                        <username>${test.mysql.db.user}</username>
                        <password>${test.mysql.db.password}</password>
                        <changeLogFile>${project.build.directory}/db.changelog-master.xml</changeLogFile>
                        <promptOnNonLocalDatabase>false</promptOnNonLocalDatabase>
                    </configuration>
                    <goals>
                        <goal>update</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

但是，如果有人指定 -Dmaven.test.skip=true 或 -DskipTests，我想跳过此插件运行。我怎么做？我尝试将执行阶段更改为“测试”，但随后我的单元测试在该插件之前运行，这不是我想要的。

这对我有用:

<configuration>
   <skip>${skipTests}</skip>
</configuration>

或

<configuration>
   <skip>${maven.test.skip}</skip>
</configuration>
