Execute script as part of mvn package - maven

My pom.xml contains
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>2.3</version>
<configuration>
<warName>${project.artifactId}</warName>
<outputDirectory>${wlp.install.dir}/usr/servers/liberty/apps</outputDirectory>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
When I run mvn package I can see this step running:
[INFO] --- maven-war-plugin:2.3:war (default-war) # frontEnd ---
That's great. However, I also want to run a shell script before the war file is created. I tried adding
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.7</version>
<configuration>
<tasks>
<exec dir="${basedir}"
executable="${basedir}/src/main/webapp/concat"/>
</tasks>
</configuration>
</plugin>
before the maven-war plugin, but it does not run. I don't even see antrun in the output of mvn. Adding the <tasks> element to the <configuration> for maven-war-plugin does nothing either.
What can I do to have maven simply run a script as part of mvn package?

The position in the pom.xml is irrelevant, you have to bind the maven-antrun-plugin execution to the correct lifecycle phase (e.g. compile) as shown below:
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.7</version>
<executions>
<execution>
<phase> <!-- a lifecycle phase --> </phase>
<configuration>
<target>
<!--
Place any Ant task here. You can add anything
you can add between <target> and </target> in a
build.xml.
-->
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
See The maven-antrun-plugin Usage Page for more details and The Maven Introduction to the Build Lifecycle for further reference.

JaCoCo not generating jacoco.exec until after skipping JaCoCo execution

I'm having trouble generating AHP reports via JaCoCo in one of my modules. When the build starts, I see JaCoCo correctly setting argLine with:
[INFO] jacoco.agent.argLine set to -javaagent:<...>/.m2/repository/org/jacoco/org.jacoco.agent/0.7.2.201409121644/org.jacoco.agent-0.7.2.201409121644-runtime.jar=destfile=<...>/target/jacoco.exec
However, the .exec hasn't been created yet by the time maven tries to run JaCoCo:
[INFO] Skipping JaCoCo execution due to missing execution data file:<...>/target/jacoco.exec
The jacoco.exec does eventually get created, after maven has skipped JaCoCo execution. Therefore, I can still generate AHP reports, if I re-run the build without cleaning.
I've seen in various other questions that I need to be careful using Maven Surefire with JaCoCo. However, I don't explicitly use argLine in my Surefire plugins, or in any plugin for that matter. I'm starting to wonder if one of the other plugins is hijacking the argLine parameter automatically like JaCoCo does.
Here is a list of all plugins used:
jacoco-maven-plugin
vertx-maven-plugin
maven-resources-plugin
maven-dependency-plugin
maven-surefire-plugin
maven-failsafe-plugin
maven-surefire-report-plugin
maven-assembly-plugin
I do see one suspicious message in the build output:
[INFO] --- maven-compiler-plugin:3.0:compile (default-compile) # <module> ---
[INFO] Changes detected - recompiling the module!
I'm not sure if that's relevant, but it appears twice before the Skipping message, and doesn't appear in a module where JaCoCo works properly.
Any ideas?

I'm not sure exactly what that plugin management part is doing, but commenting it out doesn't fix anything. I've also tried putting the JaCoCo plugin config above the surefire/failsafe config in case order mattered for plugins sharing the same goals, but that didn't help either.
*edit 2 - Looks like the problem was surefire's includes. Commenting them out somehow fixes JaCoCo's .exec generation, and JaCoCo works properly.

Anyone know why?
Just an addition to the answers already given.
It could happen that in your maven-surefire-plugin configuration you already use the argLine configuration to override something like the memory used. If you do so the argline set by jacoco-maven-plugin will not be used failing to generate the jacoco report.
In this case assign a property name to the jacoco-maven-plugin config and then reference it in your maven-surefire-plugin argLine parameter.
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.9</version>
<executions>
<!-- prepare agent for measuring unit tests -->
<execution>

<destFile>${sonar.jacoco.reportPath}</destFile>
<!-- Sets the VM argument line used when unit tests are run. -->
<propertyName>surefireArgLine</propertyName>
</configuration>
</execution>
</executions>
</plugin>

<forkCount>3</forkCount>
<reuseForks>true</reuseForks>
<argLine>${surefireArgLine} -Xmx1024m -noverify</argLine>
</configuration>
</plugin>
To solve this issue I would use the following three steps:
Determine which plugin execution is producing the jacoco.exec file. To do that, you could run Maven with debug logging enabled (mvn -X) and look for the jacoco.agent.argLine property name or its value in the output. You could also have a look at the effective POM (mvn help:effective-pom) in case the relevant configuration comes from the parent POM. Note that my guess is that it's an execution of the maven-failsafe-plugin.
Determine the phase that plugin is executed in. E.g. for maven-failsafe-plugin this would likely be integration-test.
Change the configuration of the JaCoCo plugin so that the report goal is executed later in the build lifecycle. E.g. if the jacoco.exec file is produced in the integration-test phase, you could execute the report goal in the post-integration-test phase.
In my case the solution was what #massimo mentioned, i was overriding memory values inside <surefireArgLine> tag, after i removed the tag it started generating the report and showed code coverage.
for me one of the reason for exec file not getting generated is when i placed the prepare-agent , prepare-package goals inside plugin section of pluginManagement
when i tried the same outside pluginManagement , i was sucessfully able to run the same and jacoco-exec file was generated using mvn clean install command

I did not find any solution, but I did the following:
mvn clean jacoco:prepare-agent install
create file jacoco.exec, but execute mvn sonar:sonar not create File.
Solution:
Step 1:
mvn clean jacoco:prepare-agent install
Step 2:
copy file jacoco.exec from /src/main/resources

I also faced the same problem where jacoco plugin was added to parent pom, and jacoco.exec file was generating for one of the sub modules. I had to remove the argLine arguments of maven surefire plugin, then it got generated.

Maven-antrun No ant target defined - SKIPPED

i am trying to copy a file in my maven multi-module project via antrun plugin. the file is in root of parent project:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>

<target name="copy and rename file">
<copy file="${basedir}/portal-ext.properties" tofile="${liferay.auto.deploy.dir}/../portal-ext.properties" />
</target>
</configuration>
</execution>
</executions>
i run this via mvn antrun:run the problem is i get "No ant target defined - SKIPPED" on parent and on every module. i need it to run only on parent and thought <inherited>false</inherited> would help but i doesn't. But why "No ant target defined"?

command : mvn antrun:run#ant-execute
antrun:run will only consider the plugin's configuration, not that for a specific execution, so the execution you specify is ignored. As Run a single Maven plugin execution? states, you can give your execution an id of default-cli to have it picked up.
However, the execution you configure should already be taking effect during the regular build lifecycle.
just run it like this: mvn antrun:run#copy

How do I include test classes and configuration in my war for integration testing using maven?

I currently have a maven web project that I am attempting to write integration tests for. For the structure of the project, I've defined test stubs under src/test/java, whilst the spring bean definitions for these stubs sit under src/test/resources.
What I would like to do, is that when I build my war artifact I'd like all of the test stub classes to be compiled and included in the war along with the spring bean definition files. I've tried to do it with the maven war plugin but the only things I've been able to copy are the resources. Simply put, I'd like to make use of the test class path and include all these classes in my war file.
It seems the useTestClassPath option with the maven jetty plugin would solve my problem but the current project I'm working on is currently using Tomcat 6.0. Is there another maven plugin or a way I can configure the maven war plugin to achieve my objective?
You can also do it straightforwardly. This will add both test classes and test resources to the WEB-INF/classes:
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.7</version>
<executions>
<execution>
<phase>process-test-classes</phase>
<configuration>
<target>
<copy todir="${basedir}/target/classes">
<fileset dir="${basedir}/target/test-classes" includes="**/*" />
</copy>
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
I also recommend you place it into separate profile like "integration" and also to override the package name in that profile to not be able to confuse normal war without tests packaged in and the testing war.
The full example with profile is here. You may run mvn clean package to have a war war-it-test.war without tests included, or you may run mvn clean package -Pintegration to have a war war-it-test-integration.war for the war with tests included.
I believe the following configuration for the maven war plugin would do what you want. You copy your test-classes to your WEB-INF/classes folder. You can even filter those resources.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<executions>
<execution>
<id>generate-test-war</id>
<phase>pre-integration-test</phase>
<goals>
<goal>war</goal>
</goals>
</execution>
</executions>
<configuration>
<warSourceDirectory>${basedir}/src/test/webapp</warSourceDirectory>
<warName>${project.artifactId}-test</warName>
<webappDirectory>${basedir}/target/${project.artifactId}-test</webappDirectory>
<primaryArtifact>false</primaryArtifact>
<webResources>
<resource>
<directory>${basedir}/target/test-classes</directory>
<targetPath>WEB-INF/classes</targetPath>
</resource>
</webResources>
</configuration>
</plugin>
See http://maven.apache.org/plugins/maven-war-plugin/examples/adding-filtering-webresources.html
You can use the maven build helper plugin to add additional folders to the "normal" class path.
But I would recommend to create an new folder for your integration test (for example src/it/java), and add this folder, but not the "normal" test folder (src/test/java) -- the same for the resources folder.
Instead of using the maven antrun plugin, you could instead use the maven resources plugin and configure it like this:
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<version>2.5</version>
<executions>
<execution>
<phase>process-test-classes</phase>
<id>test-classes</id>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<overwrite>false</overwrite>
<outputDirectory>${project.build.directory}/${project.build.finalName}/WEB-INF/classes</outputDirectory>
<resources>
<resource>
<directory>${project.build.directory}/test-classes</directory>
</resource>
</resources>

We need to add the below plugin to the pom.xml in order to add the test cases to jar. Thanks to #IvonSopov

</copy>
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
But after adding this line we got the build succeeded and also able to add the test case classes into the jar.. but the problem is in pom.xml it is showing as error like
Plugin execution not covered by lifecycle configuration:
org.apache.maven.plugins:maven-antrun-plugin:1.8:run
(execution:default, phase: process-test-classes)
In order to remove this error we need to include the below plugin as a separate tag within the build tag. (not inside the plugins which we added earlier.)
<pluginManagement>
<plugins>
<plugin>
<groupId>org.eclipse.m2e</groupId>
<artifactId>lifecycle-mapping</artifactId>
<version>1.0.0</version>
<configuration>

</pluginExecutionFilter>
<action>
<execute />
</action>
</pluginExecution>
</pluginExecutions>
</lifecycleMappingMetadata>
</configuration>
</plugin>
</plugins>

Now we can create the jar which includes the test classes without any errors.

Run an ant task in maven build phase before war is packaged?

When deploying a webapp I need to update some variables in UI resources, unzip some assets and concat some files, currently this is achieved via an ant task. I'm trying to run this task in the maven build process using something like this...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.6</version>
<executions>
<execution>
<id>deploy-ui</id>
<phase>prepare-package</phase>
<inherited>false</inherited>
<configuration>
<target>
<property name="buildDir" value="${project.build.directory}/${project.build.finalName}" />
<ant antfile="build.xml" target="static-assets" />
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
The above fails because the files have not yet been copied into target directory. If I set the phase to "package" the ant task runs fine and all the files are created/amended, but it's no help as the .war has already been built before the ant target is run.
Basically, I need to run my ant target near the end of the prepare-package phase.
Having looked though the Lifecycle Reference I can't workout how to expose the more granular Goals to the antrun plugin.
Any ideas?
Since I did not get any answer on my comment I guess that you want to stay using maven-antrun-plugin.
From what I've learned and experienced, if two plugins are to be executed on the same phase, then they will be executed in the order they are declared in pom.xml.
For this to work you will have to add the maven-war-plugin in the <plugins/> list after the maven-antrun-plugin.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.6</version>

<ant antfile="build.xml" target="static-assets" />
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.3</version>
<executions>
<execution>
<!-- First step is to disable the default-war build step. -->
<id>default-war</id>
<phase>none</phase>
</execution>
<execution>
<!-- Second step is to create an exploded war. Done in prepare-package -->
<id>war-exploded</id>
<phase>prepare-package</phase>
<goals>
<goal>exploded</goal>
</goals>
</execution>
<execution>
<!-- Last step is to make sure that the war is built in the package phase -->
<id>custom-war</id>
<phase>package</phase>
<goals>
<goal>war</goal>
</goals>
</execution>
</executions>
</plugin>
Added some more executions so that the default-war is first disabled, then the war is exploded and lastly the war is packaged.
As you observed this is a place where the lifecycle doesn't provide the granularity needed. I answered a similar question for someone earlier. It's not an exact answer to your question but the technique may apply.

How to call maven-antrun-plugin target without attach execution to a maven phase ?

I use maven-antrun-plugin for init config files for my project. But i need to init config files just once, when i first start to init my dev environment, not each time i launch jetty:run.
If I attach phase to process-resouces for example, each time I launch jetty, my config files are reseted.
So i configured antrun like this :
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>run</goal>
</goals>
<configuration>
<target name="init_config_files">
<!-- init files -->
</target>
</configuration>
</execution>
</executions>
</plugin>
If I launch mvn antrun:run, it just return me this error : "[INFO] No ant target defined - SKIPPED". And it is the same thing, if I specify target : "mvn antrun:run -Dtarget=init_config_files".
Try this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.7</version>
<executions>
<execution>
<id>default-cli</id>
<configuration>
<target>
<property name="compile_classpath" refid="maven.compile.classpath" />
<echo message="compile classpath: ${compile_classpath}" />
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
and run this:
mvn antrun:run
Best solution I have found so far:
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.7</version>
<executions>
<execution>
<id>go-live</id>
<configuration>
<target>
<!-- go live! -->
<exec executable="${basedir}/deploy2server.sh" failonerror="true" dir="${basedir}">
<arg value="deploy" />
<arg value="${deploy.to.server}" />
<arg value="${jetty.port.live}" />
</exec>
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
and run this:
mvn antrun:run#go-live
This solution avoids the target being run by accident, ie. it does not run just by typing "mvn antrun:run" and it also does not run during regular maven runs. I'm using this for qa auto-deployment in my jenkins instance after all modules incl integration done against the final distribution package have been successfully executed.
I just ran into the same problem and finally figured it out: If you want to run the ant tasks only once, you can set the plugin up like this:
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<configuration>
<target name="init_config_files">
<!-- init files -->
</target>
</configuration>
</plugin>
and use mvn antrun:run to execute it. That way, the ant stuff is not bound to any phase.
If you need to run some part of build on special conditions (e.g. once), you can put those parts into a Maven profile and then invoke Maven specifying profile name, e.g. mvn -p init_config_files package
