How to deploy de-Lombok-ed sources with maven

I use Lombok in my library's code and want to use delombok'ed sources when deploying library JAR with sources to maven repository.
How to configure Maven to achieve this?
Update: Most likely, you don't need to deploy delombok'ed sources (check comments below this question for details)

Include following plugins into pom.xml's build/plugins section:

"java.lang.ClassCastException" error while running scalatest through maven

I run my test cases successfully through Intellij.
But I got the "java.lang.ClassCastException" error when I run scalatest through "mvn test" command.
It's really weird. The reason might be that my scala program calls java program because some of the pure scala test cases don't have this kind of error.
Does someone know how to fix this issue?
Cause: java.lang.ClassCastException: cannot assign instance of scala.collection.immutable.List$SerializationProxy to field org.apache.spark.rdd.RDD.org$apache$spark$rdd$RDD$$dependencies_ of type scala.collection.Seq in instance of org.apache.spark.rdd.MapPartitionsRDD at java.io.ObjectStreamClass$FieldReflector.setObjFieldValues(ObjectStreamClass.java:2287) at java.io.ObjectStreamClass.setObjFieldValues(ObjectStreamClass.java:1417) at java.io.ObjectInputStream.defaultReadFields(ObjectInputStream.java:2293) at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:2211) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:2069) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1573) at java.io.ObjectInputStream.defaultReadFields(ObjectInputStream.java:2287) at java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:2211) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:2069) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1573) ...

Running test categories separately

I need to run groups of my tests in separate stages (first run group A, then run group B as if you had just started running tests)
So i decided to use a combination of maven-failsafe-plugin and junit test categories
I have the following configuration:

However maven runs my unit tests (surefire) and then the last instance of the maven failsafe plugin only (it ignores the previous 3)
How can i make it run them as well please?

The solution was as mentioned by JF Meier
you need to only have one instance of the plugin, and run them as seperate executions

How to copy a generated files from a dependency to the target of current project with maven?

I have tow maven projects resources-win and main-exec.I try to copy a dll file from a folder win of resources-win and copy it to target/classes, then i moved to the project number 2 main-exec and i try to copy a file 2 witch is in src/main/shcemas and the dll file of resources-win and paste them into target classes of the project resources-win
Here is the bloc of code whitch helps to copy a file to target of resources-win:
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<version>2.6</version>
<executions>
<execution>
<id>copy-resources01</id>
<phase>process-classes</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>${project.build.outputDirectory}</outputDirectory>
<encoding>UTF-8</encoding>
<resources>
<resource>
<directory>${basedir}/src/main/win</directory>
<includes>
<include>**/*.dll</include>
</includes>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
Here is a part of pom.xml of the project main-exec:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-libraries</id>
<phase>generate-resources</phase>
<goals>
<goal>copy</goal>
</goals>
<configuration>
<artifactItems>
<!-- win32 -->
<artifactItem>
<groupId>com.resources-win</groupId>
<artifactId>ressources-win</artifactId>
<version>1.0.0-SNAPSHOT</version>
<type>pom</type>
<destFileName>xdol.dll</destFileName>
<outputDirectory>${project.build.directory}/temp/schemas</outputDirectory>
</artifactItem>
</artifactItems>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>true</overWriteSnapshots>
</configuration>
</execution>
</executions>
</plugin>

I did like that by using an xsd file by adding to pom.xml of resources-win:
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<executions>
<execution>
<id>copy-resources-xsd</id>
<phase>process-classes</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>${project.build.outputDirectory}</outputDirectory>
<encoding>UTF-8</encoding>
<resources>
<resource>
<directory>${basedir}/src/main/schemas</directory>
<includes>
<include>**/*.xsd</include>
</includes>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<executions>
<execution>
<id>attach-artifacts</id>
<phase>package</phase>
<goals>
<goal>attach-artifact</goal>
</goals>
<configuration>
<artifacts>
<artifact>
<file>${project.build.outputDirectory}/titi.xsd</file>
<type>xsd</type>
<classifier>titi</classifier>
</artifact>
<artifact>
<file>${project.build.outputDirectory}/toto.xsd</file>
<type>xsd</type>
<classifier>toto</classifier>
</artifact>
</artifacts>
</configuration>
</execution>
</executions>
</plugin>
Then into the pom.xml of main-exec i added:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-libraries</id>
<phase>generate-resources</phase>
<goals>
<goal>copy</goal>
</goals>
<configuration>
<artifactItems>
<artifactItem>
<groupId>groupId of resources-win</groupId>
<artifactId>artifactId of resources-win</artifactId>
<version>${resources-win.version}</version>
<type>xsd</type>
<classifier>toto</classifier>
<destFileName>toto.xsd</destFileName>
<outputDirectory>${project.build.directory}/tmp/schemas</outputDirectory>
</artifactItem>
</artifactItems>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>true</overWriteSnapshots>
</configuration>
</execution>
</executions>
</plugin>
I added also the the pom.xml of main-exec the dependency of resources-win.

How to assembly a project after using proguard-maven-plugin

I am trying to add an obfuscation step while packaging my app. I supposed that I had to insert the Proguard plugin between the compiler plugin and the assembly (the assembly just put all of my app and dependencies into one single jar).
<build>
<finalName>myApp</finalName>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.2</version>
<configuration>

</configuration>

<executions>

<goal>proguard</goal>
</goals>
<configuration>
<proguardVersion>5.2</proguardVersion>
<obfuscate>true</obfuscate>
<attach>true</attach>
<appendClassifier>false</appendClassifier>
<addMavenDescriptor>true</addMavenDescriptor>

<options>

</options>
</configuration>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>net.sf.proguard</groupId>
<artifactId>proguard-base</artifactId>
<version>5.2</version>
</dependency>
</dependencies>
</plugin>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4</version>
<executions>
<execution>
<id>create-executable-jar</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
<configuration>
<descriptors>
<descriptor>assembly.xml</descriptor>
</descriptors>
<archive>
<manifest>
<mainClass>myApp.Main</mainClass>
</manifest>
</archive>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
The compiling works fine, so does the obfuscation, but the assembly seems to be made with the normal jar, not the obfuscated one.
Here is my assembly.xml if needed:
<?xml version="1.0" encoding="UTF-8"?>
<assembly>
<id>with-dep</id>
<formats>
<format>jar</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<dependencySets>
<dependencySet>
<!-- unpack les dépendances avant de les inclures dans le jar final de l'application -->
<unpack>true</unpack>
<scope>runtime</scope>
<useProjectArtifact>false</useProjectArtifact>
</dependencySet>
</dependencySets>
<fileSets>
<fileSet>
<directory>${project.build.outputDirectory}</directory>
<outputDirectory></outputDirectory>
</fileSet>
</fileSets>
</assembly>
In the end, myApp.jar is obfuscated, but myApp-with-dep.jar is not...
I also precise that I'm not quite sure about the configuration of my proguard plugin. If you see something weird, say it.
Thanks for your time.

I solved it by abandoning maven assembly plugin to shade plugin. Hope it might help someone.
