import own .jar file as dependency via Maven and have install discover and retrieve it's dependencies

So this is probably a stupid question, but I have created an own library "testlib" which I want to include in other of my own Maven projects.
This is my own librarys .pom

In order to include my library in another new project, I have created a local repository in my new projects .pom
...
<repositories>
<repository>
<id>data-local</id>
<name>data</name>
<url>file://${project.basedir}/repo</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>com.test.testlib</groupId>
<artifactId>testlib</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
</dependencies>
...
Installing my own library "testlib" via mvn install is working fine for testlib itself. The problem is, that Maven will not detect that "testlib" requires org.slf4j, hence won't get it when I run install.
I have checked other dependencies in my .m2 folder and saw they have a .pom file with the same name as the .jar (for log4j that'd be log4j-1.2.17.pom). I tried copying testlibs .pom next to its .jar and changed the name accordinly, but that doesn't do it.
What do I have to do in order to get the same functionality as any other library from maven central? In other words, I don't want a fat .jar that has all dependencies included. I want a Maven project that adds my library as a dependency to discover that it needs sl4j and include it when mvn install is run.

Mule - Project build failed when running with maven

I'm getting a failure trying to run a Hello World Mulesoft project, it looks like it related to the version of Mulesoft that I'm running, I googled around but I couldn't get any info to help resolve this issue, here is the build error:

Any idea of what's going on?
Your help is appreciated.

Maven cannot find transports:mule-transport-file:jar:3.8.4 as it is not available in the Mule Maven repository configured in your pom under <repositories>. This is the Public Mule repository, but it seems the 3.8.4 runtime and its dependencies were not made public, probably only available for Enterprise users. You can see for yourself by browsing the repository, the JAR is missing: https://repository-master.mulesoft.org/nexus/content/repositories/releases/org/mule/transports/mule-transport-file/3.8.4
You can either use Mule 3.8.1 for which your dependency is available (change Mule version in your pom) or configure the Enterprise (EE) repository if you have proper license and access (see https://docs.mulesoft.com/mule-user-guide/v/3.8/configuring-maven-to-work-with-mule-esb)
*Not related note: it seems you are running Mule EE inside Studio. Studio provide EE runtime for testing purposes, so Maven does not complain (too much) about missing EE dependencies, but if you try to run Mule EE outside Studio you will need to configure the EE repository. *

Update Setting.xml with Proxy details,if you are trying from organisation network, it seems it is not able to download all the jars

I am assuming it is your first project. You can disable Maven in order to experience MULE behavior. Right Click on the project and it provides an option to disable Maven. After that you can run your project.

Missing artifact in maven internal repository

I have added two jar files to my internal repository and created its corresponding folder directory as shown below in image. but it is showing compile time error in my pom.xml where i have added the dependency for both the jars, saying "Missing artifact common:common-jar:jar:1.0" and "Missing artifact mediator:mediator-jar:jar:1.0"
look at my pom.xml below
<properties>
<jdk.version>1.7</jdk.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<!-- Maven plugin & MOJO versions -->
<version.maven-compiler-plugin>3.1</version.maven-compiler-plugin>
</properties>

<dependency>

<artifactId>common-jar</artifactId>
<version>1.0</version>
</dependency>
<dependency>
<groupId>mediator</groupId>
<artifactId>mediator-jar</artifactId>
<version>1.0</version>
</dependency>
</dependencies>
please suggest what to do.
I think there is some problem identifying value for ${basedir} but i have also tried ${project.basedir} as well, it is also not working.

The problem lies in your url tag. Instead of <url>file://${basedir}/libs</url> try removing the double slash before ${basedir}: <url>file:${basedir}/libs</url>
You have a nice guide here if you want to check it.

First : Never use <scope>system</scope>
Follow the Example:
Project folder - C:\UX\X5SCX\GIT_STORE\SRC\FACTOR\fwk\broker\lib
<repositories>
<repository>
<id>local-repo</id>
<url>file://${basedir}/lib</url>

I don't understand why it doesn't work.
Do you have any solutions ?
Thank you

I know it was asked a year ago, but my answer might work for somebody other than me.
If creating the build tag in the pom.xml file not works, try editing the settings.xml file at your .m2 directory this way:
<pluginGroups>
...
<pluginGroup>org.apache.tomcat.maven</pluginGroup>
...
</pluginGroups>
I found the solution here:
http://tomcat.apache.org/maven-plugin-2.2/

First, there is no start goal, see the goals page of the doc.
Next, it's a plugin, you declared it as a dependency, this is why you get this error, I suggest you read the usage page of the plugin.
Here is a schematic structure of the pom.xml:
<project>
<!-- ... -->
<dependencies>
<!-- your deps here -->
</dependencies>
<build>
<plugins>
<!-- your default build plugins here -->
</plugins>
<build>
<!-- ... -->
</project>

This worked for me:
mvn clean install tomcat7:run

Run mvn with -X -e params. This should give you more information about the error.
I saw that you don't have any pluginRepositories declared. Add the following lines to your pom.xml:
<pluginRepositories>
<pluginRepository>
<id>apache.snapshots</id>
<name>Apache Snapshots</name>
<url>http://repository.apache.org/content/groups/snapshots-group/</url>
<releases>
<enabled>false</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</pluginRepository>
</pluginRepositories>

Try to delete this part from your dependency and put this line of code in plugins on your projects pom.xml.
From dependency delete this line of codes:
<dependency>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<type>maven-plugin</type>
</dependency>
and put this in ....
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
</plugin>
This will surely work.

As you may notice, the dependency is for Gephi. This is part of the error message as below:
Multiple annotations found at this line:

- Missing artifact commons-codec:commons-codec:jar:1.6
- Missing artifact org.apache.xmlgraphics:batik-util:jar:1.7

- Missing artifact javax.activation:activation:jar:1.1
- Missing artifact org.netbeans.api:org-openide-modules:jar:RELEASE721
Could anyone help me how to solve this problem? I do not know why POM does not accept the Gephi dependency however I have already added some other dependencies such as openrdf and restfb. I also added the Gephi repository as shown in the POM file. Your help is very much appreciated.

Looking at the documentation page, it looks like you'll need to add their repository to your POM, as well:
