Clear local maven repository via maven-plugin on install phase - maven

I'd like to delete the content of my entire repository (.m2/repository) before the installation phase. Of course I don't want to do it by hand so I am looking for a plugin which does the magic. So far I came across maven-clean-plugin and I am trying to use it as follows:
<build>
<sourceDirectory>src/</sourceDirectory>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.2</version>
<configuration>
<source>${jdk.version}</source>
<target>${jdk.version}</target>
</configuration>
</plugin>
<plugin>
<artifactId>maven-clean-plugin</artifactId>
<version>3.0.0</version>
<configuration>
<filesets>
<fileset>
<directory>${settings.localRepository}/</directory>
<includes>
<include>**/*</include>
</includes>
</fileset>
</filesets>
</configuration>
<executions>
<execution>
<id>auto-clean</id>
<phase>install</phase>
<goals>
<goal>clean</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
I expect this to wipe out the entire repository before downloading the new artifacts, and finally to remove the target folder from the modules. Removal of target folders works, however the wiping out the repository is kinda not working. It does wipe out the repository, however then maven complains about some artifacts required are missing so the compilation fails and returns such errors:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:2.3:resources (default-resources) on project com.google.protobuf: Execution default-resources of goal org.apache.maven.plugins:maven-resources-plugin:2.3:resources failed: Plugin org.apache.maven.plugins:maven-resources-plugin:2.3 or one of its dependencies could not be resolved: Could not find artifact org.apache.maven.plugins:maven-resources-plugin:jar:2.3 -> [Help 1]
I feel like I am pretty close to the solution. Probably I just need to tweak the parameter tags of the plugin.
Could anyone give an idea?

If you clean the entire local repository you also delete all plugins which are needed by maven and was downloaded before clean runs. You should use the dependency plaugin for delteing only jars which are dependecies of your Project:
mvn dependency:purge-local-repository
In pom you can use it like:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.7</version>
<executions>
<execution>
<id>purge-local-dependencies</id>
<phase>clean</phase>
<goals>
<goal>purge-local-repository</goal>
</goals>
<configuration>
<resolutionFuzziness>groupId</resolutionFuzziness>
<includes>
<include>org.ambraproject</include>
</includes>
</configuration>
</execution>
</executions>
</plugin>

Could I use maven and dependency-check-maven plugin to validate contens of ear file?

Is it possible to use maven and dependency-check-maven plugin to validate contens of already built ear file ? I'm trying something like below but I have no idea where I could point file which I want to verify
<build>
<plugins>
<plugin>
<groupId>org.owasp</groupId>
<artifactId>dependency-check-maven</artifactId>
<version>6.1.6</version>
<executions>
<execution>
<phase>validate</phase>
<goals>
<goal>check</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
I've found resolution. I point directory under plugin level. It forces plugin to check all files placed there
<configuration>
<scanSet>
<fileSet>
<directory>\f1\f2\f3</directory>
</fileSet>
</scanSet>
</configuration>

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?
*edit - Here's the jacoco config

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>
<id>prepare-unit-tests</id>
<goals>
<goal>prepare-agent</goal>
</goals>
<configuration>
<append>true</append>
<destFile>${sonar.jacoco.reportPath}</destFile>
<!-- Sets the VM argument line used when unit tests are run. -->
<propertyName>surefireArgLine</propertyName>
</configuration>
</execution>
</executions>
</plugin>
[...]
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19.1</version>
<configuration>
<printSummary>false</printSummary>
<redirectTestOutputToFile>true</redirectTestOutputToFile>
<forkCount>3</forkCount>
<reuseForks>true</reuseForks>
<argLine>${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
Step 3:
Add next plugin on pom.xml

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.

Can't get checksum maven plugin to execute automatically

I am using the Maven Checksum Plugin, and I am having problems getting it to execute after the war has been built. Here's my configuration in my superpom under the section:
<build>
...
<pluginManagement>
<plugins>
<plugin>
...
</plugin>
<plugin>
<groupId>net.ju-n.maven.plugins</groupId>
<artifactId>checksum-maven-plugin</artifactId>

</fileSet>
</fileSets>
</configuration>
</plugin>
<plugin>
...
</plugin>
</plugins>
</pluginManagement>
</build>
When I run mvn package, the plugin isn't executed. Not there's an error, but just doesn't execute. Nothing is printed out during the build process. The war is processed, the build is declared successful, and the plugin doesn't execute.
I've tried removing the <phase> entities and run mvn verify because according to the documentation on the plugin, the checksum:files goal is automatically bound to the verify phase. Still no execution.
However, the plugin does work if I run:
$ mvn checksum:files
What am I missing in my configuration?
The plugin is not executed because it is declared under the pluginManagement section of your pom.
You should move the configuration of checksum-maven-plugin outside pluginManagement like this:
<build>
<plugins>
<plugin>
...
</plugin>
<plugin>
<groupId>net.ju-n.maven.plugins</groupId>
<artifactId>checksum-maven-plugin</artifactId>
<version>1.3-SNAPSHOT</version>

<directory>${project.build.directory}/artifacts</directory>

How to resolve a Maven "The packaging for this project did not assign a file to the build artifact" error?

I’m using Maven 3.2.3. I used to be able to run “mvn clean install” on my WAR project and the WAR would get installed to my local repository. However, I recently added a configuration so that my WAR would be constructed in place (config is below). Now, when I run
mvn clean install
I get the error
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-install-plugin:2.5.2:install (install) on project myproject: The packaging for this project did not assign a file to the build artifact -> [Help 1]

Maven - Excluding Resource from a specific artifact

I'm new to maven, and found myself stuck with something which is really bothering me.
I have a multi-module project, and my parent pom.xml contains the following plugin:
<plugin>
<artifactId>maven-remote-resources-plugin</artifactId>
<executions>
<execution>
<id>process-remote-resources</id>
<goals>
<goal>process</goal>
</goals>
<configuration>
<resourceBundles>
<resourceBundle>
${shared.resources.version}
</resourceBundle>
</resourceBundles>
<includes>
<include>version.info</include>
</includes>
</configuration>
</execution>
</executions>
</plugin>
This code generates a version.info file and places them in each of my module jar files.
I was wondering if it's possible to make this code create the version.info file for only 2 modules out of the 3.
For example if I have modules: A, B and C.
I would like the version.info file to be in A and B but not in C.
I hope I explained myself well enough, in case not please let me know.
Thanks in advance,
Meny
Best solution would be moving this plugin configuration to the project/build/pluginManagement element of the parent pom:
<pluginManagement>
<plugins>
<plugin>
<artifactId>maven-remote-resources-plugin</artifactId>
<executions>
<execution>
<id>process-remote-resources</id>
<goals>
<goal>process</goal>
</goals>
<configuration>
<resourceBundles>
<resourceBundle>
${shared.resources.version}
</resourceBundle>
</resourceBundles>
<includes>
<include>version.info</include>
</includes>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</pluginManagement>
and call it at project/build/plugins in module poms:
<plugins>
<plugin>
<artifactId>maven-remote-resources-plugin</artifactId>
</plugin>
</plugins>
if such refactoring of parent pom is not allowed then override plugin configuration with skip set into true or use the none phase to disable unwanted plugin calls:
