running mvn package -e didn't give any noticeably different output and mvn package -X didn't give me anything I could understand. How would I go about fixing it? Looking in the pom.xml file, the only release related thing I could see was the <release>10<\release> but idk what to change that to if that is the problem. I'm assuming I have to change things in the file to fit what versions of java and maven I have but I'm pretty new to the both of them and don't really know what I'm looking for.

Building two ears from two wars in one webapp

as always, excuse me if I make a silly query or one that is easily resolved. In a project I'm working on I was asked to find out if it's possible to build two wars from one webapp. This I could solve in the following way:

Each of these war has the same classes but differs in the xhtml files. One points to mobile phone components and the other points to landline phone components.
After doing this, I realized that it was necessary to build an ear for each one of them, each one with its root context and perform the deploy in wildfly. But I can't find the way to do it. On the one hand I don't know how to point to the wars that are built in the execution in the webapp, and on the other hand I don't know if the way is only with one ear for both or it is necessary to build two. I would be very grateful if someone could give me a hand with this. Thank you very much!
Update
Taking the example I found in this link: Maven ear plugin multiple artifacts content
I made the following changes:

Now the executions are done and maven creates three ears, the first one, which is called "FacturaElectronica" I created it to test that it actually works. The problem is that the three ears have exactly the same content as "FacturaElectronica". I think it is because maven does not find the dependence towards "facturaelectronicafija" and "facturaelectronicafija". Maybe because when I create these WARs in executions I can't add a version to them. Somebody could clarify me this please? Thank you very much!

I would create a multi-module project where each WAR and each EAR are separate modules.
The classes would be a JAR module that is used in the two WAR modules

I had to make some corrections, but I managed to leave it working as expected.

Previously the dependencies generated only a meta inf file, this was because they were with a scope provided, when you switch to compile it works correctly.

Test case failure in sonar

I am trying to get sonar report for one of my project.
I have run mvn clean install
Running blah.blah.BlahTest1

I'm not a Maven expert, though but, I have implementation wherein, during the maven lifecycle, I execute some of the JUnits to find the Code Coverage and Sonar, of course. I'm attaching my pom. Maybe this helps.

Can I exclude maven plugin folders from the target folder?

I'm using some plugins to build my maven project.
During the "install" phase, maven create plugin directories inside my target folder, but I don't need them.
There's an option to avoid the creation of this directories that allows me to continue to use those plugins?
In my case are 'maven-archiver' and 'surefire' (that is also empty after the building).

those directories (surefire & maven-archiver) gets generated by surefire and archiver plugin respectively
when you do mvn clean install it goes through following phases
validate, clean, compile, test, package, install
these two plugin are by default tied to
phases surefire - > test
and
archiver -> package
so those plugins gets executed and that generates these directories, if you don't want their execution you can skip sure-fire's execution that will stop running any test cases by configuring your pom.xml following way
<project>
[...]
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.17</version>
<configuration>
<skipTests>true</skipTests>
</configuration>
</plugin>
</plugins>
</build>
[...]
</project>
to stop export of test result you can either set it to output to some other directory by setting reportsDirectory property or you can stop generating xml reports using disableXmlReports property

Mention exclude directories inside pom.xml file
Inside exclude tags mention your files which you dont want.

Why isn't my Maven plugin run in the build lifecycle?

I have tried to add a goal to my maven lifecycle with the following pom part. I defined a new plugin and configured it with phase and execute information.
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.openjpa</groupId>
<artifactId>openjpa-maven-plugin</artifactId>
<version>2.2.0</version>
<configuration>
<includes>**/entity/*.class</includes>
<addDefaultConstructor>true</addDefaultConstructor>
<connectionDriverName>com.ibm.db2.jcc.DB2Driver</connectionDriverName>
<enforcePropertyRestrictions>true</enforcePropertyRestrictions>
<sqlFile>${project.build.directory}/database.sql</sqlFile>
</configuration>
<executions>
<execution>
<id>sql</id>
<phase>generate-resources</phase>
<goals>
<goal>sql</goal>
</goals>
</execution>
<execution>
<id>enhancer</id>
<phase>process-classes</phase>
<goals>
<goal>enhance</goal>
</goals>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>org.apache.openjpa</groupId>
<artifactId>openjpa</artifactId>
<version>2.1.1</version>
</dependency>
</dependencies>
</plugin>
</plugins>
</pluginManagement>
</build>
Then I run maven with mvn:install But the plugin is not run?

Make sure that there is a dependency on the plugin and that the plugin is in build/plugin not build/pluginmanagement/plugin.
Try with something like this:
<dependencies>
<dependency>
<groupId>org.apache.openjpa</groupId>
<artifactId>openjpa</artifactId>
<version>2.1.1</version>
</dependency>
</dependencies>
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.openjpa</groupId>
<artifactId>openjpa-maven-plugin</artifactId>
<version>2.2.0</version>
<configuration>
<includes>**/entity/*.class</includes>
<addDefaultConstructor>true</addDefaultConstructor>
<connectionDriverName>com.ibm.db2.jcc.DB2Driver</connectionDriverName>
<enforcePropertyRestrictions>true</enforcePropertyRestrictions>
<sqlFile>${project.build.directory}/database.sql</sqlFile>
</configuration>
</plugin>
</plugins>
</pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.openjpa</groupId>
<artifactId>openjpa-maven-plugin</artifactId>
<executions>
<execution>
<id>sql</id>
<phase>generate-resources</phase>
<goals>
<goal>sql</goal>
</goals>
</execution>
<execution>
<id>enhancer</id>
<phase>process-classes</phase>
<goals>
<goal>enhance</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>

pluginManagement is supposed to configure plugin, which is invoked at command line.
If you want to bind plugin to some execution phase - simply move it into build->plugins section of your pom.xml
