I want to execute linux shell commands with maven. Here is what I tried:
<plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>exec-maven-plugin</artifactId> <version>1.1.1</version> <executions> <execution> <goals> <goal>exec</goal> </goals> </execution> </executions> <configuration> <executable>hostname</executable> </configuration> </plugin>
But the above is not working. Can you please help me out.

Here's what's been working for me:
<plugin>
<artifactId>exec-maven-plugin</artifactId>
<groupId>org.codehaus.mojo</groupId>
<executions>
<execution><!-- Run our version calculation script -->
<id>Version Calculation</id>
<phase>generate-sources</phase>
<goals>
<goal>exec</goal>
</goals>
<configuration>
<executable>${basedir}/scripts/calculate-version.sh</executable>
</configuration>
</execution>
</executions>
</plugin>
The problem here is that I don't know what is expected. With your current setup, invoking the plugin on the command line would just work:
$ mvn exec:exec
[INFO] Scanning for projects...
[INFO] ------------------------------------------------------------------------
[INFO] Building Q3491937
[INFO] task-segment: [exec:exec]
[INFO] ------------------------------------------------------------------------
[INFO] [exec:exec {execution: default-cli}]
[INFO] laptop
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESSFUL
[INFO] ------------------------------------------------------------------------
...
The global configuration is used, the hostname command is executed (laptop is my hostname). In other words, the plugin works as expected.
Now, if you want a plugin to get executed as part of the build, you have to bind a goal on a specific phase. For example, to bind it on compile:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.1.1</version>
<executions>
<execution>
<id>some-execution</id>
<phase>compile</phase>
<goals>
<goal>exec</goal>
</goals>
</execution>
</executions>
<configuration>
<executable>hostname</executable>
</configuration>
</plugin>
And then:
$ mvn compile
[INFO] Scanning for projects...
[INFO] ------------------------------------------------------------------------
[INFO] Building Q3491937
[INFO] task-segment: [compile]
[INFO] ------------------------------------------------------------------------
[INFO] [resources:resources {execution: default-resources}]
[INFO] Using 'UTF-8' encoding to copy filtered resources.
[INFO] skip non existing resourceDirectory /home/pascal/Projects/Q3491937/src/main/resources
[INFO] [compiler:compile {execution: default-compile}]
[INFO] Nothing to compile - all classes are up to date
[INFO] [exec:exec {execution: some-execution}]
[INFO] laptop
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESSFUL
[INFO] ------------------------------------------------------------------------
...
Note that you can specify a configuration inside an execution.
