Transitive Dependency doesn't work properly - maven

I am trying to configure a general POM that will contain some basic dependencies that probably all my projects are going to use.
I made a project with POM.xml,with packaging set to pom and added some basic dependencies.
Then i am trying to add this project as a dependencies using this code in my project:
<dependencies>
<dependency>
<groupId>com.arslan</groupId>
<artifactId>general-deps</artifactId>
<version>1.0</version>
<type>pom</type>
</dependency>
</dependencies>
I expected that NetBeans would automatically start downloading the depedencies of the dependency(transitive depedencies),but it doesn't.This whole thing works fine with inheritance,but i wanna try it without inheritance — just to see it works...What could be the problem?I run install on the general-deps project so that it's available in my local repository.

Using different JBoss BOM in profiles

I have a general question about the usage of the BOM from JBoss and WildFly.
Is the a way to build a project for both JBoss 7 and WildFly 10 using a different profile?
I tried to copy the BOM definition from WildFly into a profile like this:
<profile>
<id>WildFly10</id>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.wildfly.bom</groupId>
<artifactId>wildfly-javaee7-with-tools</artifactId>
<version>${version.jboss.bom}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<!-- JSON -->
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>${version.json}</version>
</dependency>
</dependencies>
</dependencyManagement>
</profile>
Of course accourdingly with a JBoss7 profile.
But this way it won't add important libraries to the lib folder, i.e. this definition is in an ear pom and a subproject (war) adds the json dependency. Without a profile maven adds the json jar inside the lib folder, but not if I put it inside a profile.
After I read that changing dependencies in a profile is an anti-pattern [1] I would like to know how I can build my project for both JBoss7 and WildFly 10.
Update
Ok sorry for this quick shot of a question. Here are more details.
project structure:
|-parent (pom)
|- myapp (war)
|- core (jar)
|- deployment (ear)
So deployment is the project building the whole ear containing myapp as a web apllication and core as a library. myapp has a dependency to core and core to json.
In order to have all needed depenedencies with the correct version I included wildfly-javaee7-with-tools in the dependencyManagment. Also is the version of json defined in there. The core project has the json library as a normal dependency.
At this point this should be quite standard. But the thing is I want to be able to build for JBoss 7 and WildFly 10, for what I have to change
<dependency>
<groupId>org.wildfly.bom</groupId>
<artifactId>wildfly-javaee7-with-tools</artifactId>
<version>${version.jboss.bom}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
to
<dependency>
<groupId>org.jboss.bom</groupId>
<artifactId>jboss-javaee-6.0-with-tools</artifactId>
<version>${version.jboss.bom}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
Of course ${version.jboss.bom} will be changed from 10.1.0.Final for WildFly to 1.0.7.Final for JBoss.
In order to do so I tried to move wildfly-javaee7-with-tools into a profile. My first guess was to only move this dependency to a profile. But then the json jar doesn't get included. After that I also tried to move jsonlike above.
Without seeing the original not-profiled nor profiled pom in whole cannot say anything accurate but educated guess.
You have json in profiles dependency management.
Is it also in poms main dependencies without version? If not it will not be copied to lib nor packed. It is only managed by profiles <dependencyManagement>.
Does json need managing per profile? It seems to have ${version.json} which then anyway would be same for each profile if copied as it is in the example.
For me it seems that fix might be that you remove the json from profiles dependencyManagement and add it to main dependencies as normal dependency - this just to make profiling more simple - it can be managed but if not needed set the version of json directly to dependency.

Maven not importing External Library into project after adding to .pom file in Intellij

I'm having trouble correctly importing a library into a project that I'm running. I have added the library as a dependency in the .pom, refreshed the pom, run mvn clean install, and I have set auto-import up so that the project gets updated correctly, but the project does not get added as an External Library, and I can't use it in my project. I get no errors. What am I doing wrong?
Here is the relevant part of my pom
..properties
<crowd.version>2.5.0</crowd.version>
.. end properties
<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.atlassian.crowd</groupId>
<artifactId>crowd-integration-springsecurity</artifactId>
<version>${crowd.version}</version>
<scope>runtime</scope>
</dependency>
</dependencies>
</dependencyManagement>
Here is the question I was following to debug my error:
Import Maven dependencies in IntelliJ IDEA
I think you missed the point of dependency management; read more in official docs. This is a feature that you can centralize common dependency information that is then shared been different projects. All by itself, this definioition will not import the dependency.
What you probably want is just a plain dependency: drop the dependencyManagement tags, and move you dependency into the correct block in the pom.

Adding a dependency existing internally as a dependency

My project is a fairly large project consisting of many maven modules (but not microservices). I was trying to do Moving from spring to spring-bom on WAS but seems lot of clashes in versions. So for example one of my modules is using commons-collectionsversion 2.6.0 and my current project is using 3.2.2. I want the same jar to be used across. Since its more of a migration project I cannot do changes in container or repository changes at this time. I should only make sure that all the version are compatible with each other. My plan :
I want to include a dependency which is with in some other dependency
into the current pom as a dependency.
Also I want other jars in this pom (which exists as a dependency) to included the dependency
Is there anyway to do it?
I didn't completely understand your question, but the can help you to define a cross-module dependency version, as long as you place it in the parent-pom file.
<dependencyManagement>
<dependency>
<groupId>com.group</groupId>
<artifactId>project-1</artifactId>
<version>1.0.0</version>
</dependency>
</dependencyManagement>
and then define the dependency in the relevant module without providing it a version (it will be inherited from the parent-pom's <dependencyManagment> tag:
<dependencies>
<dependency>
<groupId>com.group</groupId>
<artifactId>project-1</artifactId>
</dependency>
</dependencies>

how to add my one project jar in another maven project in netbeans

I have one project jar oauth.
I want to add it in another maven project . I tried to change pom.xml file but no effect. Can anyone please suggest me?
I tried to add following dependency in my pom.xml file:
<dependency>
<groupId>com.payupaisa.oauth</groupId>
<artifactId>auth</artifactId>
<version>1.0.0</version>
<type>jar</type>
<scope>system</scope>
<systemPath>${basedir}/src/main/webapps/WEB-INF/lib/auth.jar</systemPath>
</dependency>
With the assumption that you have that auth.jar in your local repository (as it builds fine).
Why don't you give a try like this.
<dependency>
<groupId>com.payupaisa.oauth</groupId>
<artifactId>auth</artifactId>
<version>1.0.0</version>
<scope>compile</scope>
</dependency>
Honestly speaking I don't prefer to give the jar location in my pom file and using scope as system, I leave this task to handle by Maven to resolve all the artifacts either by searching in local maven repository first(/.m2) or in MAVEN CENTRAL REPO if it is a 3rd party jar.

Adding POM type dependency using m2eclipse, unable to resolve

I am trying to add Hector dependencies to my POM. My IDE is Eclipse, and I am also using m2eclipse. Adding dependencies of JAR type is not a problem, but this dependency is of type POM. I have tried almost everything usual including cleaning, building, and using import scope but nothing seem to have helped. When I try to add import me.prettyprint.hector.api.Serializer;
I get the error "The import cannot be resolved".
Is there anything else I need to do to use POM type dependencies or is there a better way of using dependencies of POM types in the project?
I believe his question is not as obvious as simply including the necessary dependency. I have experienced this problem too and am looking for a solution. The problem can be clearer stated as the following:
Let's say I have two maven projects (project A and project B). Project A is a simple web-app which wants to include dependencies as stated in project B. However, project B packaging type is "pom". This should allow all of project B's dependencies to be included into project A. Here is an example:
Project A (packaging is "war"):
<dependencies>
<dependency>
<groupId>com.foo</groupId>
<artifactId>B</artifactId>
<version>1.0</version>
<type>pom</type>
</dependency>
</dependencies>
Project B (packaging is "pom")
<dependencies>
<dependency>
<groupId>commons-lang</groupId>
<artifactId>commons-lang</artifactId>
<version>2.4</version>
</dependency>
</dependencies>
What we'd like to see in Eclipse is when you run maven eclipse:eclipse on Project A, that you can see the commons-lang-2.4.jar file as a dependency under project A such that you can resolve it in your code when imported. This is not happening and I'm still looking for such a solution.
The error indicates that the relevant class is missing in your classpath. A search of this class indicates, it is available in hector-core
This discussion indicates how this dependency can be imported, viz. adding the following entry to your project pom (or choosing this appropriately in m2eclipse).
<dependency>
<groupId>me.prettyprint</groupId>
<artifactId>hector-core</artifactId>
<version>0.7.0-29</version>
</dependency>
