Answer 1

As of exec-maven-plugin version 1.6.0, it appears <configuration> sections within <execution> blocks are ignored unless you specify an id.

Try changing your command line, substituting exec:exec@foo for exec:exec with the plugin block changed to include an id foo as follows:

      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>exec-maven-plugin</artifactId>
          <executions>
              <execution>
                  <id>foo</id>
                  <phase>package</phase>
                  <goals><goal>exec</goal></goals>
                  <configuration>
          <executable>${perl.path}</executable>
                      <arguments>
                          <argument>../tools/scripts/createScript.pl</argument>
                          <argument>${project.build.directory}/${project.artifactId}</argument>
                          <argument>ors</argument>
                          <argument>org.marketcetera.ors.OrderRoutingSystem</argument>
                          <argument>${project.build.directory}/${project.artifactId}</argument>
                          <argument>orsadmin</argument>
                          <argument>org.marketcetera.ors.security.ORSAdminCLI</argument>
                      </arguments>
                  </configuration>
              </execution>
          </executions>
      </plugin>

Answer 2

You forgot to specify perl.path variable in <executable> tag.

<executable>${perl.path}</executable>

Add this to your pom parent:

<properties>
    <perl.path>path/to/perl</perl.path>       
</properties>

Answer 3

I resolved this error by specifying the required plugin in pom.xml as follows

            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>exec-maven-plugin</artifactId>
                <version>3.0.0</version>
                <configuration>
                    <executable>java</executable>
                    <arguments>
                        <argument>-classpath</argument>
                        <classpath />
                        <argument>com.ocloud.Alarm.App</argument>
                    </arguments>
                </configuration>
            </plugin>

Answer 4

Just compile before execution

clean compiler:compile exec:java

Answer 5

This error The parameter 'executable' is missing or invalid can also happen if the exec-maven-plugin plugin is configured in a child maven module and you run the command from the parent directory.

To fix that, simple change your working directory to where the plugin is used.
