Is there a way to fork Java VMs with Maven Failsafe plugin. I am using Junit with Serenity Runner

I have all the required dependencies but not including here.
I am unable to run test parallelly with forkCount or methods. It works fine would the sureFire plugin but I cannot use the surefire plugin to generate serenity reports.
I have tried a combination of forkCount and parallel that didn't work either.
I was able to fork multiple Java VMs using the sureFire.
I am trying to run test parallelly in multiple virtual machines. Our application is swing based java application and we are using LeanFt to automate the testing process.

I figured out how it actually works. All you have to do is add Surefire plugin with Failsafe plugin when you use both of them. It works like a charm.

Unable to run pom.xml

I am trying to run a pom.xml that ultimately runs my java main class. On running the pom.xml I am getting the error:-
The pom.xml looks something like this (main class resides within ScreenShotUtility package):-
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.1.1</version>

</plugin>
</plugins>
</build>
<properties>
<maven.compiler.source>1.6</maven.compiler.source>

</properties>

Add
<build>
<defaultGoal>exec:java</defaultGoal>
...
</build>
to the pom and run
mvn
Why exec:java? Because it is a shorthand for exec-maven-plugin:java what is the name of the build-plugin.

Using git-commit-id-plugin in maven works in package-phase but not in install-phase

I'm using the git-commit-id-plugin (see https://github.com/ktoso/maven-git-commit-id-plugin). It packages correctly when I'm setting up an annotated tag like e.g. v1.0.0, meaning the target-directory has a jar file named deploy-test-Test-v1.0.0.jar.
The problem is, that the maven install phase creates the following files in my local .m2-directory:
Test-${git.closest.tag.name}
|- deploy-test-Test-${git.closest.tag.name}.jar
|- deploy-test-Test-${git.closest.tag.name}.pom
|- _remote.repositories
I've tested this with the example pom.xml.
What can I do to get the same name (deploy-test-Test-v1.0.0.jar)?

Also refer to this to work around the "plugin execution not covered by lifecycle" error in Eclipse/SpringToolSuite
see: How to solve "Plugin execution not covered by lifecycle configuration" for Spring Data Maven Builds

I've found a solution that worked fine for me. Just added the gmaven-plugin like in the pom-snippet below and the versions will be adapted to the last git-tag.
<plugin>
<groupId>org.codehaus.gmaven</groupId>
<artifactId>groovy-maven-plugin</artifactId>
<version>2.0</version>

<execution>
<phase>install</phase>
<goals>
<goal>execute</goal>
</goals>
<configuration>
<source>project.artifact.version='${git.closest.tag.name}';</source>
</configuration>
</execution>
</executions>

I've also used groovy-maven-plugin to update project.properties. Without this pom.xml was generated with variables that have not been parsed.
project properties
<properties>
<gitClosestTagName>${git.closest.tag.name}</gitClosestTagName>
<gitClosestTagCommitCount>${git.closest.tag.commit.count}</gitClosestTagCommitCount>
</properties>
build final name atteribute
<finalName>${project.artifactId}-${gitClosestTagName}.${gitClosestTagCommitCount}</finalName>

project.build.finalName="${project.artifactId}-${gitClosestTagName}.${gitClosestTagCommitCount}";
project.properties['gitClosestTagName']=${git.closest.tag.name};
project.properties['gitClosestTagCommitCount']=${git.closest.tag.commit.count};
println("project.build.finalName=${project.build.finalName}");
</source>
</configuration>
</execution>
</executions>

Maven can't compile project even when I can debug it

I transferred a big java project to maven and replaced all the libraries used with maven and I can run debug or start just fine meaning that it works normally but for some reason whenever I try to run maven test or install or anything that tries to compile it using maven it fails.
This is my pom file (I use nexus for third party jars):

I have tried a lot of plugins and tried deleting the .m2 repository but nothing seems to help.
All the errors I get are
[ERROR] /C:/Users/worx-pc-01/git/PbClient/pbclient2/src/pb/ui/panels/admin/workorders/configuration/namingConvention/GenericNamingConventionTableModel.java:[10,24] package com.pb.hibernate does not exist
or
[ERROR] /C:/Users/worx-pc-01/git/PbClient/pbclient2/src/pb/ui/panels/admin/workorders/configuration/namingConvention/GenericNamingConventionTableModel.java:[192,36] cannot find symbol
symbol: class PbPwoNamingConfiguration
location: class pb.ui.panels.admin.workorders.configuration.namingConvention.GenericNamingConventionTableModel
The package does exist and I don't understand why this won't work like its supposed to.
Am I doing something wrong since I just started using maven.

The error messages suggest to me that either the package com.pb.hibernate doesn't exist in your project (maybe it has been renamed and your IDE didn't update every use properly) or it exists in an external dependency which your IDE has somehow got in its path when running/debugging, but the dependency isn't defined correctly in your pom, and so running mvn clean install fails

Maven2 Binding to a custom Phase

I have a custom plugin that is defined using the pom.xml

Running
mvn blah:touch
Creates a text file in the target directory as expected. I now create a lifecycles.xml file in the resources directory specified in the pom
<lifecycles>
<lifecycle>
<id>touch</id>
<phases>
<phase>
<id>package</id>
<executions>
<execution>
<goals>
<goal>touch</goal>
</goals>
</execution>
</executions>
</phase>
</phases>
</lifecycle>
</lifecycles>
In another maven project, I would like to bind the running of mvn blah:touch to an execution task similar to this
...
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.2.1</version>
<executions>
<execution>
<id>test1</id>
<phase>blah:touch</phase>
<goals>
<goal>java</goal>
</goals>
<configuration>
<mainClass>mainClass=org.sonatype.mavenbook.weather.Main</mainClass>
</configuration>
</execution>
</executions>
</plugin>
...
However running this creates the text file but doesn't attempt to run org.sonatype.mavenbook.weather.Main
Is this the correct approach?
Ultimately what I would like is to have multiple execution sections in the exec-maven-plugin that are not bound to the default phases. Logically it would look like this
...
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.2.1</version>
<executions>
<execution>
<id>test1</id>
<phase>blah:touch</phase>
<goals>
<goal>java</goal>
</goals>
<configuration>
<mainClass>mainClass=org.sonatype.mavenbook.weather.Main</mainClass>
</configuration>
</execution>
<execution>
<id>test2</id>
<phase>blah:touch2</phase>
<goals>
<goal>java</goal>
</goals>
<configuration>
<mainClass>mainClass=org.sonatype.mavenbook.weather.SomeOtherClass</mainClass>
</configuration>
</execution>
</executions>
</plugin>
...
So if I run mvn blah:touch then org.sonatype.mavenbook.weather.Main will be executed and if I run mvn blah:touch2 then org.sonatype.mavenbook.weather.SomeOtherClass will be executed instead.
It seems like it should be straightforward to do but there's nothing in the documentation that seems to point out how to do this.

You can not use the exec-maven-plugin for this and you do not need the lifecycle.xml if you only would like to execute your plugin during a build.
To execute your plugin during a specific Maven phase, you simply have to add
<plugins>
<plugin>
<groupId>your.group.id</groupId>
<artifactId>your.artifact.id</artifactId>
<executions>
<execution>
<id>unique-execution-id</id>
<goals>
<goal>the.goal.of.your.plugin</goal>
</goals>
<phase>maven.phase</phase>
<configuration>
....
</configuration>
</execution>
</executions>
</plugin>
</plugins>
Please specify the goal in the goal element without the prefix.
