Errors in Maven compiler, not in Eclipse compiler

Hi,

When building our SARL project via Eclipse, it builds fine with no errors. When building with Maven however, this is the result:

[INFO] Validate and generate.
[INFO] Starting validation for input: 'ElevatorSimActions.sarl'
[INFO] Starting validation for input: 'ElevatorSimPercepts.sarl'

This appears as if it is similar to #380. For reference, we are currently building with SARL Maven Plugin 0.4.0 due to #503.

If it helps, I can provide some of the problem files or our pom.xml.

Cheers,

Dear @ssardina.

The following command line is not the good one:

java -cp ~/.m2/repository/sarl-controller/sarl-controller/0.3.3/sarl-controller-0.3.3.jar:/home/ssardina/.m2/repository/io/janusproject/io.janusproject.plugin/0.4.1/io.janusproject.plugin-0.4.1.jar io.janusproject.Boot io.sarl.elevatorsim.SimulatorProxyAgent

Why is it not the good one?

The io.janusproject.plugin module contains the compiled of the Janus platform, but not the classes of the other libraries that are needed running Janus. Consequently, when you launch the application with a standard Java approach, class files are missed from the classpath.

For solving this issue, you could use two approaches:

• Use maven for running the application. Maven has all the dependencies in its configuration, and is able to build the correct classpath: update the pom.xml file for specifying the main class to be run, and launch mvn exec:java
• Use the standard Java launching approach (as you tried) with the correct Jar file for Janus. You need to download the jar file that contains all the needed class for running Janus: http://maven.sarl.io/io/janusproject/io.janusproject.kernel/2.0.5.0-SNAPSHOT/io.janusproject.kernel-2.0.5.0-20161004.030955-7-with-dependencies.jar ; then you could use the following command line:

java -cp ~/.m2/repository/sarl-controller/sarl-controller/0.3.3/sarl-controller-0.3.3.jar:/path/to/io.janusproject.kernel-2.0.5.0-with-dependencies.jar io.janusproject.Boot io.sarl.elevatorsim.SimulatorProxyAgent

We have planed to make the things easier from the CLI, see #149.

That’s a great news. I will start the release plan for the version 0.4.2 in order to provide a stable version with the patches. Thank you for initial issue submission.
