Making symbolic link named ".m2" to Gradle JAR repo

After many years of using Maven, I am used to that my JARs are in ~/.m2/ directory, so I created myself a link as follows:

$ ln -s ~/.gradle/caches/modules-2/files-2.1 ~/.m2 

$ ls -alt ~/.m2/

Maven: executing JAR created with Maven

In this tutorial we will learn how to create an executable jar with Maven and run it from command line.


Let's add a maven-jar-plugin to your pom, make sure you specify your main class as such:

<mainClass>exec.MyApp</mainClass>

Run Maven:

uki@ JavaFxSceneSwitch $ mvn clean install[INFO] Scanning for projects...[INFO]                                                                         [INFO] ------------------------------------------------------------------------[INFO] Building JavaFxSceneSwitch 1.0-SNAPSHOT[INFO] ------------------------------------------------------------------------...[INFO] Installing .. to /Users/uki/.m2/repository/edu/clcillinois/cit137/JavaFxSceneSwitch/1.0-SNAPSHOT/JavaFxSceneSwitch-1.0-SNAPSHOT.jar[INFO] Installing ...[INFO] ------------------------------------------------------------------------[INFO] BUILD SUCCESS[INFO] ------------------------------------------------------------------------[INFO] Total time: 1.822 s[INFO] Finished at: 2015-04-21T14:57:43-05:00[INFO] Final Memory: 15M/91M[INFO] ------------------------------------------------------------------------

Run the app from the ROOT of your project:

uki@ UKI_LUCAS $ java -jar  /Users/uki/.m2/repository/edu/clcillinois/cit137/JavaFxSceneSwitch/1.0-SNAPSHOT/JavaFxSceneSwitch-1.0-SNAPSHOT.jar

The JavaFX app should start, if you start it from other folder, observe how the Image path behaves.

Java: find jar

When you are looking for a given Java class, you can use this online database to locate jars:

Example, looking for log4j

http://www.findjar.com/index.x?query=log4j

Among others I get response:

[JAR] log4j-1.1.3.jar in log4j/log4j/1.1.3
[JAR] log4j-1.2.11.jar in log4j/log4j/1.2.11
[JAR] log4j-1.2.12.jar in log4j/log4j/1.2.12

Maven: installing apk, or arr, or jar in .m2

Sometimes you get a built artifact (apk, arr, jar) and instead of keeping it in your Downloads, or com up with a nice folder structure, you can simply put it in your Maven .m2 repository, that what it is designed for.

In this tutorial we will discuss upgrading Maven on Mac OS X.




While trying building with Maven I was getting errors related to version number (below 3.1) 

mvn install

Error: Could not find or load main class org.codehaus.plexus.classworlds.launcher.Launcher

To update my maven I have to do the following sequence of steps.

$ mvn -version

Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 07:51:28-0600)

I had to uninstall the older version 3.0

$ brew uninstall maven30

Uninstalling /usr/local/Cellar/maven30/3.0.5...

Trying to install newest I noticed that I tried it before, but it was not linked

$ brew install maven

Warning: maven-3.2.3 already installed, it's just not linked

The easiest way to fix that is to uninstall and install again:

$ brew uninstall maven

Uninstalling /usr/local/Cellar/maven/3.2.3...
$ brew install maven

Installing Maven

After few years of not needing it, I came back to Maven, reason being that I cannot use Gradle for reasons beyond my control and Ant does not describe complex projects structures required.
