exec-maven-plugin equivalent / alternative - bash

Question

In Maven, we can use exec-maven-plugin to execute bash commands in the build.
Which plugin of Central Repository can perform the same task?
I ask it because I have to execute a bash command after another plugin that needs to be executed in the same phase only after exec-maven-plugin, so I can't do it directly inside the exec-maven-plugin.
The bash command that I want to execute in the Maven build is the following:
cat file1 >> file2
Thanks in advance.

I managed to solve my issue with maven-antrun-plugin with the <concat> task:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.8</version>
<executions>
<execution>
<id>final step</id>
<phase>install</phase>
<configuration>
<target>
<concat destfile="${project.build.directory}/${project.artifactId}-${project.version}.sh" binary="yes">
<fileset file="${project.build.directory}/script/self-installer.sh" />
<fileset file="${project.build.directory}/${project.artifactId}-${project.version}.tar.gz" />
</concat>
<chmod file="${project.build.directory}/${project.artifactId}-${project.version}.sh" perm="+x"/>
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
This is the equivalent of the bash cat command.
Keep in mind that if you are concatenating a binary file, you have to set binary="yes", otherwise the Ant task will corrupt the final file.
In any case, this is still not a bash-based solution, it's only a trick that uses Ant routines, so it's not a real equivalent of exec-maven-plugin
