Integrated an maven project to an existing maven project

I have a existing db Maven Java project in eclipse. And the second is also in Maven project with a global pom and subdirectory pom. What is the easiest way to integrate both projects into one project ? I tried to add these subfolders with the pom file. But i got the failure modules is an invalid element. Maybe there is another way to add the second project. The first project is an embedded neo4j db and the seconde project is the jung frame work. Which has also sub pom files.

Maven Surefire Test Rerun Parameter Does Not Re-Run Failing Tests

Maven surefire does not rerun failing tests. I tried to change the surefire version to 3.0.0-M4, 3.0.0-M5. Use commandline option -Dsurefire.rerunFailingTestsCount=3, added <surefire.rerunFailingTestsCount>2</surefire.rerunFailingTestsCount> to the pom file, and added 2 to the configurations of surefire plugin; ran mvn install multiple times. However, nothing seems to work and Surefire runs failing tests just once. The pom file of the project I am working with is:

I am a little bit lost what might be causing the failing tests to be executed multiple times as I tried a lot of different suggestions on stackoverflow.
Thanks in advance!

There are some missing configurations under maven-surfire-plugin. Please, have a look at the working configuration:

Error creating shaded jar: Problem shading JAR java.lang.SecurityException: Invalid signature file digest for Manifest main attributes

I created fat jar(common-1.0-SNAPSHOT.jar) using maven shade plugin. It generated successfully. This common dependency include to new maven project and try to generate fat jar. But it given above error. I tried with different answers as exclude MANIFEST files. After excluding MANIFEST files it asked to exclude .class files in common.jar library.
Need I use any signing method to common library or is there any way to ignore this error.
Thank you.

Maven shade plugin not relocating

I've been trying to shade a package from one jar into my own and when I build the project using IntelliJ, it does not shade it in. I've been trying different things from online for over an hour and I thought it would be much simpler to ask on here. I have Maven 3.5.0 installed (mvn -version returns the proper version) and I can see the jar I'm trying to shade in the repositories directory.
My pom.xml:

java.lang.NoClassDefFoundError on running project with Java, but works when running with mvn exec:exec

I'm compiling and running some source code I got from a project called Structr (https://github.com/structr/structr). I'm able to run the program correctly with a maven mvn command but not using the JVM java command.
The compilation step goes well with maven clean install -DskipTests
On running the front-end (in the structr-ui directory), it goes well if using maven exec:exec but fails on java -cp target/lib/*;target/structr-ui-0.8.2.jar org.structr.Ui. I have some stack trace indicating java.lang.NoClassDefFoundError on org.structr.core.entity.AbstractNode and org.structr.core.EntityContext. What I find strange about this is that the maven pom.xml file in the exec entry we have

The mvn exec:exec statement looks equivalent to the java JVM statement. This question may be basically; What is maven doing differently than java, that in the maven case making the program run correctly?
Edit - additional maven and java debugging information
On mvn -X exec:exec, The output is given here http://roberthoff.com/files/mvn_exec_trace.txt
And on java -server -Dfile.encoding=utf-8 -XX:+UseNUMA -Xms1g -Xmx1g -classpath target/lib/*
;target/structr-ui-0.8.2.jar org.structr.Ui we have http://roberthoff.com/files/java_trace.txt

You have a valid question here, because according to the Maven documentation on the exec:exec goal you would need to have the <\classpath> stanza in your configuration in order to include the entire project module classpath.
However, it appears as though Maven is running the program with the fully (and properly) configured classpath for some reason.
In order to get to the bottom of the problem, I'd run Maven with the -X command line argument and carefully scan through the debug output until I found the exact command it runs. Then I'd try running it from the same directory, ensuring I am using the same Java installation and see if it works.

Notice the maven-dependency-plugin in the pom. It copies all dependencies during the package phase to target/lib folder and then they are on classpath. Following should work:
maven clean package -DskipTests
java -cp target/lib/*;target/structr-ui-0.8.2.jar org.structr.Ui
