Create EAR with Maven and Eclipse

I have a web-application(TestWeb) and multiple java dependency projects(TestCommon,TestModule).
I was able to build all 3 projects using maven.It has created war file and jar file out of it.
I need to create .ear file using maven. How can I create ear and build them?

In the current .pom you are building an ear and you are giving the same ear as a warModule.
You should give a .war artefact for webmodule in the ear-plugin

EAR is packing two copies of WAR and JAR projects

My Maven EAR project packs my EAR with two copies of each of my libraries. One copy is always appended with the version (In my case 1.0-SNAPSHOT). Is there something screwed up in my POMs?
I keep getting these type of errors when i try and deploy to server:
Servlet [blah...] and Servlet [blah..] have the same url pattern: [/RegistrationService_V10].
My EAR project POM looks like this :
<?xml version="1.0" encoding="UTF-8"?>

In the maven-ear-plugin, you have to specify your ejbmodule and webmodule
<plugin>
<artifactId>maven-ear-plugin</artifactId>
<version>2.8</version>
<configuration>
<modules>
<ejbModule>
<groupId>com.huwag</groupId>
<artifactId>AlmexOffice-ejb</artifactId>
</ejbModule>
<webModule>
<groupId>com.huwag</groupId>
<artifactId>AlmexOffice-web</artifactId>
<contextRoot>/custom-context-root</contextRoot>
</webModule>
</modules>
</configuration>
</plugin>
Could you give us the feedback if it works better?

My problem is that if I do an mvn install in abc-datasource the dependency versions are pulled from the parent pom properties as expected. However if I do mvn install from abc-window that references abc-datasource then the versions are not resolved, I get:
[ERROR] Failed to execute goal on project abc-window: Could not resolve dependencies for project hu.abc.ringcore:abc-window:jar:1.0-SNAPSHOT: Failed to collect dependencies for [junit:junit:jar:4.10 (test), hu.abc.ringcore:abc-datasource:jar:1.0-SNAPSHOT (compile)]: Failed to read artifact descriptor for org.apache.commons:commons-lang3:jar:${commons-lang3.version}: Could not transfer artifact org.apache.commons:commons-lang3:pom:${commons-lang3.version} from/to central (http://repo.maven.apache.org/maven2): IllegalArgumentException: Illegal character in path at index 70: http://repo.maven.apache.org/maven2/org/apache/commons/commons-lang3/${commons-lang3.version}/commons-lang3-${commons-lang3.version}.pom
Both project have the same parent pom, so why doesn't it work..?

Use dependencyManagment in parent pom
<dependencyManagement>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>${junit.version}</version>
</dependency>
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>${commons-lang3.version}</version>
</dependency>
</dependencies>
</dependencyManagement>
add all versions in parent pom, and use dependencies without version in children
EDIT
/pom.xml <-parent pom
/abc-window/pom.xml <-child module
/abc-datasource/pom.xml <-child module
and parent pom should contains
<project
...
<properties>
...
</properties>
<modules>
<module>abc-datasource</module>
<module>abc-window</module>
</modules>
<build>
<pluginManagment>
...
</pluginManagment>
</build>
<dependencyManagment>
...
</dependencyManagment>
</project>

The parent in abc-window is listed as:
<parent>
<relativePath>../foobar-common/pom.xml</relativePath>
<groupId>hu.abc.ringcore</groupId>
<artifactId>foobar-common</artifactId>
<version>1.0</version>
</parent>
The parent in abc-datasource is listed as:
<parent>
<relativePath>../foobar-common/pom.xml</relativePath>
<groupId>hu.ratesoft.ringcore</groupId>
<artifactId>foobar-common</artifactId>
<version>1.0</version>
</parent>
So, they do not have the same groupId.
