Trying to build with maven: package my.external.package does not exist

Hi, I created a maven project and did some coding (yay) which required me to use some libraries that are in any maven repository (:sad:)

so I imported the .jar files of those libraries and did happily code without Eclipse complaining about anything (except for staying up too late).

then now I'm proudly trying to build my very first .war with maven, I run -> maven build... clean package and then I get a whole bunch of errors saying that

[ERROR]
Mojo:
org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile

Reason:
/Users/me/Documents/myproject/src/main/java/com/mydomain/myclass/myController.java:[17,36] package org.someother.project.package does not exist

what is wrong? How can this be? I'm in despair, save my friday the 13th

Somewhere in your pom you are referencing org.someother.project.package, where is that?

What are the contents of the myController.java file? Do you have this line:

I'm not sure I can reference org.someother.project.package in my pom.xml, since that package is not a maven project, it's not in any repository.

my pom.xml looks like this:



What I did do, in the build path of the project, was to link the .jar in which org.someother.project.package is. So I have a symbolic link "lib" source folder in my project.

As I said, Eclipse doesn't seem to mind, however I noticed that I don't have any .class files generated (even though auto build is on).

Does your pom.xml for the war project have the built jar as a dependency?

the pom.xml in my previous post is that of my war project

Sorry, didn't have my coffee yet In that case you need to add in that 3rd party jar as a dependency in your pom.xml file.

Is it possible to add that as a directory or do I have to add all the .jar manually one by one?

You need to add the jar manually, see for assistance, you'll need to install that jar into your local repository however.

OK will do

I didn't think of adding them to my local, that's brilliant (and simple) thanks

You'll want to probably be able to do this as a long term solution (your local repo is temporary after all). Nexus and Artifactory are two highly recommended dependency managers to try.

Thanks for the input, I've hear of Nexus before and will definitely take it into consideration. My intent is to convince my boss and co-workers that maven is good for us, but I need to tame the beast if I want to present it

Sounds good! In that case I'd recommend reading the Free PDF - "Maven - Definitive Guide", it'll quickly get you up to speed (just google for it).
