From the documentation, the unpack goal of the maven-dependency-plugin plugin binds by default to the process-sources phase.
So could you change (or just remove) the <phase>process-resources</phase> from the plugin configuration

Include Scala project in Java Maven dependency

Im new to scala, Im trying to include scala project into my java project.
I have separate scala and java project and Im using scala in java.
It is working fine when I add scalaTest to my java project build path. Is there any way I can edit my pom.xml that automatically refer the scalaTest project while maven build?.
I have added scala dependency in my pom.xml
Or is there any way that I can include both java and scala files into my java project and run ?

If you the following pom.xml you should be able to compile Java and Scala sources from within the same project via mvn.

Answers to my own question
Add Scala project in class path (buildpath) of java project.
Export Scala project as jar and import to your java project.
To include both java and scala in single java project, follow this.
Include java files into - src/main/java
Include scala files into - src/main/scala
Use this pom.xml
Download project from https://github.com/rthoma24/Java-Scala.git

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

How to skip the maven antrun copy/shade:shade goal dynamically?

I am using maven for configuration of an application consisting of multiple small services. Most of the services developed in java share the same maven configuration, as in the same build lifecycle, some shared resources (like spring AMQP).
So I have organized the shared resources in a SuperPom.
While the shade plugin doesn't really seem to disturb the install process, the antrun plugin of course won't find any of the files it should copy, due to there not being created any jar files by the shade plugin.
As I'd like the configuration of the shade/antrun plugin to be abstracted in the SuperPom, I need to skip the shade/copy goal.
I have tried mvn clean install -Dmaven.shade.skip=true, mvn clean install -Dmaven.copy.skip=true, mvn clean install -Dmaven.shade.shade.skip=true
Here is a small sample for you to play with:

Did you try setting the phase of maven-shade-plugin to none in the super-pom and then overriding this in the client poms?
So in the parent pom:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.3</version>
<executions>
<execution>
<id>shade</id>
<phase>none</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<!-- ... -->
</configuration>
</execution>
</executions>
</plugin>
And in the child poms that need it:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<!-- no need to specify version -->
<executions>
<execution>
<id>shade</id>
<phase>package</phase>
<!-- no need to specify configuration -->
</execution>
</executions>
</plugin>

The maven-shade-plugin doesn't have a parameter to skip. Often the shade-plugin isn't there just for fun, so you might wonder if you really want to skip this. If you think it is still valid, you have to create a profile with activation like this:
<activation>
<property>
<name>skipShade</name>
<value>!true</value>
</property>
</activation>
This way it is activated by default, unless you add -DskipShade or -DskipShade=true.

Maven 3.6.1 gives you a new approach.
In the superPom you can define a profile for your shading configuration:

</profile>
</profiles>
In the user's settings.xml under .m2 you can add a profile of the same id to enable the shade profile configuration of your superPom. This gives you the option to simple toggling the shading from inside your IDE like Intellij IDEA (only tested in Intellij).
<settings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
https://maven.apache.org/xsd/settings-1.0.0.xsd">
...
<!-- toggle shading from inside Intellij IDEA -->
<profiles>
<profile>
<id>shade</id>
</profile>
</profiles>
<!-- Shade Profile has to be activeProfile to be
able to explicitly disable shading -->
<activeProfiles>
<activeProfile>shade</activeProfile>
</activeProfiles>
</settings>
In the child project you can add a .mvn/maven.config file to your child project template to predefine shading for the project by default. (Requires a CVS template that is used to predefine a company standard.)
The approach using a maven.config is useful if some of your team members do not have the profile in their settings.xml file and you have to take care that shading will be done most of the time.
.mvn/maven.config:
-Pshading
The profile can also be activated by default using jenkinsfile for Jenkins by passing -Pshade. It will overwrite the maven.config setting. To disable use -P!shade
Please note if you are using maven.config file in Intellij (2020.2.2): The .mvn/maven.config file must exists in the subdirectory of the root aggregator pom folder. Building a subproject form the IDE does not respect a .mvn/maven.config file on the subproject level at the moment. Running a mvn command from the command line in the subproject folder will repespect both, the child project .mvn/maven.config and the parent .mvn/maven.config.

Disabling the maven shade plugin worked for me. The build was stock trying to produce the dependency reduced pom file before I disabled the Maven shade plugin.

The skip option was introduced in version 3.3.0 of the shade plugin, so now skipping can be done dynamically using, for example, properties:
<properties>
....
<skipShaded>true</skipShaded>
</properties>
...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>3.3.0</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<skip>${skipShaded}</skip>
...
</configuration>
</execution>
</executions>
</plugin>
In the above the default is to skip, and this can be overridden with passing -DskipShaded=false to mvn.

After I run the maven install it is working...
Maven run configurations:
The problem is that my generated .jar it doesn't have the dependencies included....
How can I configure pom.xml to include all my dependencies in .jar format and not unpacked.. because it seems that unpacked are not working correct...
To be sure that including all jars is ok.. I downloaded and added each library into jar's /lib folder and the jar is running... so.. my only question is: How can I configure pom.xml in order to add all my dependencies in jar format?
I tried all methods:
assembly:assembly
assembly:single
assembly:single with my descriptor (an assemble.xml file) but it wasn't working
maven copy dependencies plugin but still not working with Eclipse Maven - m2e
I am out of solutions... can anyone tell me a proper way to add my dependencies in jar? I can't believe that maven is so complex and I can't find an answer to my question everywhere..
Thank you in advance

There are a couple of ways of doing this.
1) If you want an uber-jar (repacked with all dependencies), look into using and configuring the maven-shade-plugin:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>1.6</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>com.group.id.Launcher1</mainClass>
</transformer>
</transformers>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
This will unpack all dependencies and merge them into one JAR file.
2) If you want to deliver a bundle (zip, tar.gz, etc) with the unpacked JAR files in the bundle (perhaps under lib/) then you need to look into the maven-assembly-plugin:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.3</version>
<executions>
<execution>
<id>create-distro</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<descriptors>
<descriptor>src/main/assembly/dist.xml</descriptor>
</descriptors>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
Note that this requires an assembly descriptor src/main/assembly/dist.xml and example looks like this:
<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0">
<id>distribution</id>
<formats>
<format>zip</format>
</formats>
<dependencySets>
<dependencySet>
<useProjectArtifact>false</useProjectArtifact>
<useTransitiveDependencies>false</useTransitiveDependencies>
<unpack>false</unpack>
<scope>runtime</scope>
<fileMode>0755</fileMode>
<directoryMode>0755</directoryMode>
<outputDirectory>bin</outputDirectory>
<includes>
<include>com.group.id:project-launch1</include>
<include>com.group.id:project-launch2</include>
</includes>
</dependencySet>
<dependencySet>
<useProjectArtifact>false</useProjectArtifact>
<useTransitiveDependencies>true</useTransitiveDependencies>
<unpack>false</unpack>
<scope>runtime</scope>
<fileMode>0644</fileMode>
<directoryMode>0755</directoryMode>
<outputDirectory>lib</outputDirectory>
<includes>
<include>com.group.id:project-lib1</include>
<include>com.group.id:project-lib2</include>
<include>com.group.id:project-lib3</include>
<include>com.group.id:project-lib4</include>
</includes>
</dependencySet>
</dependencySets>
</assembly>
And since you are now assembling dependencies, you have better define the dependency in the pom.xml, like so:
<dependencies>
<dependency>
<groupId>com.group.id</groupId>
<artifactId>project-launch1</artifactId>
<version>0.0.1-SNAPSHOT</version>
<type>jar</type>
</dependency>
<dependency>
<groupId>com.group.id</groupId>
<artifactId>project-launch2</artifactId>
<version>0.0.1-SNAPSHOT</version>
<type>jar</type>
</dependency>
<dependency>
<groupId>com.group.id</groupId>
<artifactId>project-lib1</artifactId>
<version>0.0.1-SNAPSHOT</version>
<type>jar</type>
</dependency>
... and so on ...
</dependencies>
3) If you are delivering a bundle with an executable JAR file launcher, you will likely need to add a maven-jar-plugin configuration in addition to the maven-assembly-plugin:
<dependencies>
<dependency>
<groupId>com.group.id</groupId>
<artifactId>project-lib1</artifactId>
<version>0.0.1-SNAPSHOT</version>
<type>jar</type>
</dependency>
<dependency>
<groupId>com.group.id</groupId>
<artifactId>project-lib2</artifactId>
<version>0.0.1-SNAPSHOT</version>
<type>jar</type>
</dependency>
<dependency>
<groupId>com.group.id</groupId>
<artifactId>project-lib3</artifactId>
<version>0.0.1-SNAPSHOT</version>
<type>jar</type>
</dependency>
... and so on ...
</dependencies>
<build>
<plugins>
<plugin>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<addMavenDescriptor>false</addMavenDescriptor>
<compress>true</compress>
<manifest>
<mainClass>com.group.id.Launcher1</mainClass>
<addClasspath>true</addClasspath>
<classpathPrefix>../lib/</classpathPrefix>
</manifest>
</archive>
</configuration>
</plugin>
</plugins>
</build>
Note that the "addClasspath" directive adds the project dependencies to the class path. This is needed for JAR launchers, as they explicitly ignore all CLASSPATH environmental variables.
