我在使用 Maven Exec 插件时有些挣扎。我想使用插件执行两个单独的mvn命令,所以我只需要执行mvn exec:exec即可执行所有命令。

以下两个命令分别运行良好:

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.6.0</version>
    <configuration>
        <executable>mvn</executable>
        <arguments>
            <argument>clean</argument>
        </arguments>
    </configuration>
</plugin>

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.6.0</version>
    <configuration>
        <executable>mvn</executable>
        <arguments>
            <argument>package</argument>
        </arguments>
    </configuration>
</plugin>

这是我尝试将两者结合起来,以便用一个命令执行它们:

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.6.0</version>

    <executions>
        <execution>
            <id>id1</id>
            <phase>package</phase>
            <goals>
                <goal>exec</goal>
            </goals>
            <configuration>
                <executable>mvn</executable>
                <arguments>
                    <argument>clean</argument>
                </arguments>
            </configuration>
        </execution>

        <execution>
            <id>id2</id>
            <phase>package</phase>
            <goals>
                <goal>exec</goal>
            </goals>
            <configuration>
                <executable>mvn</executable>
                <arguments>
                    <argument>package</argument>
                </arguments>
            </configuration>
        </execution>
    </executions>

</plugin>

不幸的是,当我现在执行mvn exec:exec时,我收到以下错误消息:

当您mvn exec:exec在命令行上运行时,它会运行一个<execution>with an <id>of default-cli。这解释了错误消息,因为没有在您的 POM 中配置的<id>default-cli</id>执行。<executable>

要解决您的问题,请查看配置插件指南。它解释了如何从命令行执行一个目标,而<id>不是default-cli

mvn exec:exec@id1 exec:exec@id2
