installing 3rd party JARs

I have a maven project in Eclipse called TdkUtils, with this pom.xml:
This is a utils project. So I want to create a jar, put it in the repository and use it in another projects.
...
<groupId>com.tdk</groupId>
<artifactId>tdkUtils</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<name>tdkUtils</name>
...
But I got these errors when installing the plugin:
MacBook-Pro-de-nunito:tdkUtils nunito$ mvn install:install-file -Dfile=target/tdkUtils-0.0.1-SNAPSHOT.jar
[INFO] Scanning for projects...

If you just execute mvn install while inside the same directory with the util pom.xml file, maven will install the jar file into local repository for the user.
After that, the jar file can be used by the same user from other projects.

you can install a jar to local repo without pom.xml like this:
mvn install:install-file -Dfile=target/tdkUtils-0.0.1-SNAPSHOT.jar -DgroupId=com.tdk -DartifactId=tdkUtils -Dversion=0.0.1-SNAPSHOT -Dpackaging=jar

MAVEN SUREFIRE PLUGIN ERROR

Im building a custom maven project for jenkins. After using the command
mvn -Plight-test install
I recieve this error .Please help. I have also added the plugin for surefire exception in the pom.xml file, but it isn't working! The error log is as follows :

Compile :

I had the same issues and I found out that the problem was that some of tests tried to create a System link and it was not possible because I didn't start my IDE (IntellijIdea) as administrator in Windows.
I started Intellij as administrator and that solved the problem.
Skipping test is not a good practice when developing.

mvn -Dmaven.test.skip=true -DskipTests=true clean install
use this command

Rerun with mvn -Plight-test install -rf jenkins-core -X to isolate the error

Trying to run mvn exec and getting mojo exception on plugin

So I am running
mvn exec:java -Dexec.mainClass=”com.utm.csc.HTMLParser” -Dexec.args=”http://www.simplehtmlguide.com”
for my Java project. It runs in Eclipse but with the command above, gives me the following errors:

This is an image of my paths
I am using OS X El Capitan on a 64-bit MacBook Air mid-2012. What am I doing incorrectly?

The error is that you are giving the argument incorrectly. Your command should be:
mvn clean compile exec:java -Dexec.mainClass=com.utm.csc.HTMLParser -Dexec.args=http://www.simplehtmlguide.com
Notice the lack of quotes. This can be hinted from the error message:
java.lang.ClassNotFoundException: ”com.utm.csc.HTMLParser”
means that somehow, Java searched for a class called ”com.utm.csc.HTMLParser” but it didn't find any, simply because it is actually named com.utm.csc.HTMLParser, without the quotes.

Don't forget to compile first. exec:java doesn't do it by default.
mvn clean compile exec:java -Dexec.mainClass=”com.utm.csc.HTMLParser” -Dexec.args=”http://www.simplehtmlguide.com”

Error Transfer artifact : Connection Timeout

I'm trying to build a version of OpenTripPlanner on my system for the first time. There are a couple of dependencies errors, out of which I was able to resolve the first one by downloading the jar manually and adding it to the .m2/repository
However, I'm unable to get around the second dependency error. Following is the error log for the maven build

I know it has something to do with core-1.0.7.jar but am unable to get around it

Turns out that switching the repository from OpenGeo to Conveyal was all that was required. Discussion thread which helped me to solve it : https://groups.google.com/forum/#!topic/opentripplanner-users/pKPGut4iCyQ
