Ok, now I have a good MANIFEST.MF (with good class-path) !
Every .jar of htmlunit folder are in build path + lib folder.

Still same error

 

Hello, help me please
=> Imports √ (all imports needed)
=> BuildPath √ (all .jar of htmlunit folder)
=> Manifest √ (2 jar per line, full path)

What else ??

 

You need to include your dependency's files with the jar you are exporting.

 

@1Rogue HOW ???
I JUST Exported my jar with plugin.yml and config.yml Whaaat else ???

 

To be honest I would use maven (with shade), as manually managing dependencies and jarfile information is a lot of setup-specific work and is not very portable.

 

@1Rogue
Yaayy thanks ! I just wanted to ask you, how to use Maven
Which one I have to download please ?
I just have to put maven.jar in "plugins" and to add it in build path ? That's all ?

 

No, maven has nothing to do with build paths. It replaces any need to mess with build paths and jarfile manifests entirely. Maven will do the compiling of your plugin for you.

Maven usually has integrated support in any decent (note: Not eclipse) IDE. As for getting started: http://maven.apache.org/guides/getting-started/maven-in-five-minutes.html (skip the command-line command in "creating a project", your IDE can do that part).

 

@1Rogue
thanks,
pc2:~ THEO$ mvn --version

Erreur : impossible de trouver ou charger la classe principale org.codehaus.plexus.classworlds.launcher.Launcher

 

Are you running maven from the command line or is that an output from your IDE?

 

@1Rogue
"pc2:~ THEO$" is the prefix in Terminal.app of all commands... I don't know what you mean
And terminal is returning me :
Erreur : impossible de trouver ou charger la classe principale org.codehaus.plexus.classworlds.launcher.Launcher

 

Yeah, it cannot find the main class when you use Terminal. What IDE do you use?

 

I use jdk1.7 and I configured the Java home here !
@1Rogue

Hum however in fact I can't found the right path to maven...... It is said to write :
export PATH=$PATH:/usr/local/apache-maven/apache-maven-3.2.5/bin
HOWEVER
apache-maven-3.2.5/bin
..... bin folder doesn't exist here O.O


can't it be an issue with class-path relatives ?

 

Your PATH is a system variable that tells things such as your command line where to find executables. So instead of typing

Code:

/usr/local/apache-maven/apache-maven-3.2.5/bin/maven -options

You can do:

Code:

maven -options

However the point I'm trying to stress is this: You don't need to do this on the command line. If you use an IDE for writing your code it usually is integrated with maven. In rusty french:

Si tu utilizeras un «IDE» pour écrire ton code, alors tu n'est pas nécessaire de le faire sur la «command line»
