proguard obfuscation of package-private members shared across maven modules - java

I'm using the com.pyx4me.proguard-maven-plugin to obfuscate code in a multi-module project. How can I obfuscate a module that depends upon 'friend' methods from a different (obfuscated) module? I wish to keep everything from the base module but shrink/optimize as much as possible in the dependent module. I've tried a variety of 'keep*', 'dontoptimize' and 'dontshrink' options but nothing seems to help. Cross-posting from https://groups.google.com/forum/#!topic/pyx4me-users/1auM9xSQkLY.
The above project structure yields the following error:
[proguard] Warning: test.Bar: can't find referenced method 'void x()' in class test.Foo
[proguard] Warning: there were 1 unresolved references to program class members.
[proguard] Your input classes appear to be inconsistent.

Use -dontskipnonpubliclibraryclassmembers option (in testproj.b/pom.xml).

Why does maven not run Junit tests after 'clean'

I am building a Java RESTful web service using dropwizard. The tests do not run consistently though. If I run the test manually, then mvn test the test will run.
If I run mvn clean test I get
No tests to run.
Until I run the test manually again. My project structure is as follows:

I found the problem. It problem was with my test folder structure.
[] src
[] main
[] ...
[] test
[] java
[] ...
java was not set as the "Test Sources Root". So the test-classes were not generated.
I was able to find a solution after #chrylis pointed me in the right direction in his comment.

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.

Creating library jar with dependent jars with maven dependency plugin

I want to create a jar (No main class) which is later used as UDF in apache pig. When i creating the jar with maven the dependent jars are not include inside the output jar.
pom file looks like this
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

<plugins>
<plugin>

</plugins>
</build>

<groupId>org.apache.pig</groupId>
<artifactId>pig</artifactId>
<classifier>h2</classifier>
<version>0.13.0</version>
</dependency>
</dependencies>
</project>
But the resulted jar always throw
NoClassDefFoundException
when running with apache pig

Here is an extract of my pom.xml which builds a jar with dependencies:
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.1</version>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-assembly</id> <!-- this is used for inheritance merges -->
<phase>package</phase> <!-- append to the packaging phase. -->
<goals>
<goal>attached</goal> <!-- goals == mojos -->
</goals>
</execution>
</executions>
</plugin>
The difference I see is the goal: you use single, I use attached.

The build was successful without any errors, but I checked the Jar file and there was no class files in it.
