Unknown lifecycle phase on Maven

I tried to re-run my maven project in another laptop with the exact same file. I compiled it with this command:

mvn exec:java -Dexec.mainClass=id.tumbs.App

This works on the laptop I was doing the project for, while throwing out an error on another laptop. The error code is

[ERROR] Unknown lifecycle phase ".mainClass=id.tumbs.App". You must specify a valid lifecycle phase or a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal>.

I tried everything from what the error link told me and nothing work. Any solution, please?

Solution

Try specifying your main class in double quotes:

mvn exec:java -Dexec.mainClass="id.tumbs.App"

Similarly, you can use -Dexec.args="arg0 arg1" to pass arguments.

If you're on Windows, you need to apply quotes for exec.mainClass and exec.args:

mvn exec:java -D"exec.mainClass"="id.tumbs.App"

If you're doing this more frequently, you can add the parameters into the pom.xml like this:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.2.1</version>
  <executions>
    <execution>
      <goals>
        <goal>java</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <mainClass>id.tumbs.App</mainClass>
    <arguments>
      <argument>arg0</argument>
      <argument>arg1</argument>
    </arguments>
  </configuration>
</plugin>
