Since I need to download a lot of jars/dependencies to create a special JRE distribution for special application, to avoid to download on maven repository web site.
I created an project on Maven, put my dependencies on pom.xml and it has been downloaded all jars "~.m2/repository" (user folder) but it's very difficult to get jar by jar of the ".m2/repository" folder, and I really dont know what my project uses since this folder contains all jars from all projects.
Has any magic command copy only the jars of my project needs?
Yes,
As you did, create a app, edit you pom.xml, and put all your dependencies into dependencies block.
<dependencies>
<dependency>
<groupId>org.deeplearning4j</groupId>
<artifactId>deeplearning4j-core</artifactId>
<version>1.0.0-beta5</version>
</dependency>
<dependency>
<groupId>org.deeplearning4j</groupId>
<artifactId>deeplearning4j-modelimport</artifactId>
<version>1.0.0-beta5</version>
</dependency>
<dependency>
<groupId>org.nd4j</groupId>
<artifactId>nd4j-native-platform</artifactId>
<version>1.0.0-beta5</version>
</dependency>
<dependency>
<groupId>com.google.cloud.dataflow</groupId>
<artifactId>google-cloud-dataflow-java-sdk-all</artifactId>
<version>2.5.0</version>
</dependency>
</dependencies>
Then ou can create your package, open a terminal navigate to your project and execute the command:
mvn package
After the BUILD you can copy only the jars that the project uses (also all dependencies), using the next command:
mvn dependency:copy-dependencies
And check the folder "target/dependency" and all jars will be stored into this folder, and you can copy this for your JRE/lib/ext.
You can use maven-dependency-plugin for this. See below sample pom.xml file.

You need to use maven-install-plugin to include your custom third-party JAR into your final JAR.
Apache Maven has a guide for it but specifically for your case:
Remove the scope & systemPath XML tags for your third-party dependency from your pom.xml file as they are not needed
Run mvn install:install-file -Dfile=C:/Users/abcd/Desktop/amazon-dynamodb-implementing-priority-queuing-master/target/awsblog-queueing-1.0.0.jar -DgroupId=com.awsblog.queueing -DartifactId=awsblog-queueing -Dversion=1.0.0 to install the local JAR in your local repository
Run mvn clean package

Then I have the 4 sub-modules benchmark, core, algo, tests with their own pom.xml all referencing the parent project correctly (with the correct version number). The actual project is from neo4j which you can find here.
I tried doing a maven clean install and the project builds successfully without any issues. However, when I import the projects to Eclipse, I get many errors (mostly from the parent project) that states either ... cannot be resolved to a type or ... cannot be resolved.
I tried doing a Maven -> Update Project without any success. I'm in the Project Explorer view in Eclipse with all 5 projects at the same level.
I also tried adding a Active Maven Profiles in Eclipse, however, did not resolve the issue. My Embedded Maven version is 3.3.9/1.8.2.20171007-0216
I found the issue. Problem was, my Eclipse workspace was the directory called workspace. However, my maven projects were in a subfolder I created called my_project. When I cloned the repo, I cd into my_project and did git clone.
So, instead of choosing the highest level workspace folder as my Eclipse workspace, I chose the /workspace/my_project as workspace and the issue resolved.
I have a Maven web project in which I must run some Selenium UI tests (with JUnit). However, when I build the project (goals: “clean install”) the Selenium tests don’t work because the Tomcat server hasn’t started yet.
I have added a plugin snippet that I found online (the tomcat7-maven-plugin) but it doesn’t seem to do anything.
It might be important to know that my Selenium tests use a Firefox driver with a different binary from my default Firefox install (an older version of Firefox portable to work with the older version of Selenium).

Sorry, I'm not very familiar with EAR+EJB things, because for most cases I encountered it was gross over-complication. However, if that's what you need to use...
Check out an answer explaining them in some detail.
Basically EJB is supposed to contain implementations for some interfaces that are defined elsewhere. WAR will not know what implementations it'll get at runtime, it just knows the interfaces, so it should depend on the interfaces. Let's call those interfaces API and you'll get the following project structure:
parent
|- api
|- ejb
|- war
\- ear
Where:
API contains just interfaces (don't specify packaging, it'll default to jar)
EJB depends on API to implement some/all interfaces
WAR depends on API to use them (e.g. via interface injection points)
EAR depends on WAR and EJB to bundle the two into final archive
If this is too complex for your use case, you can start with just WAR containing everything and refactor later. You can deploy .war to any application server and even just containers without full application server functionality.
We are using GWT in our product with mojo gwt-maven-plugin 2.4 to compile the GWT code.
But we observed that when we run mvn install, the gwt maven plugin is running the permutations even when no code changes are made to GWT code.
After struggling on this issue for quite some time, we were able to reproduce it with a simple setup using 2 maven projects:
1st project(MyGwtMavenSampleSource) : Contains the GWT code along with the gwt module xml file
2nd project (MavenBuilderMod): Contains the MyGwtMavenSampleSource as maven dependency and will build the war
file.
Below are the poms for both the projects:

So, the question is, how can we make gwt-maven-plugin / compiler to run the permutations only on code change in this kind of setup.
Note: This works as expected (i.e permutations are run only when the code is changed) if gwt module xml file is placed in the same maven module that contains the gwt-maven-plugin
The root issue is Maven's broken support for incremental builds, and possibly broken incremental-build support in the gwt-maven-plugin (particularly if you're still using a more-than-2-year-old version!).
The gwt-maven-plugin somehow sees that the gwt.xml file has changed (track the build of your first module, ideally it should really be a no-op if nothing changed; re-copying the resources and/or rebuilding the JAR would probably be enough to trigger the issue downwards), and particularly is more recent than the nocache.js file it produced.
I think a better setup is to run the gwt-maven-plugin in the first module and package everything in a ZIP or WAR, that you can then use as a WAR overlay. It unfortunately makes running DevMode a bit harder, but it's workable.
