I have a program that I want to run on Raspberry PI with LaunchPi but when I add the other program into build path the Eclipse throws a message with the following text: Can not start launch configuration java.lang.NullPointerException

Any Ideas of how can I run it on Pi;

Can you share more details on the project's classpath - maybe the .classpath file? Is this java project to java project dependency? It might be an issue similar to #10

I build two project simultaneously and lets say that project A is needed for project B. If I put project A in required projects of project B then I got the null poiner exception. The classfile contains : <?xml version="1.0" encoding="UTF-8"?>

In order to include project A I add the class folder only in project B libraries (only this is working).

Thank you for your time!

I found out that I cannot just copy-paste the content of the file so I include it bellow adding a space after each "<" at the beginning

< classpath> < classpathentry combineaccessrules="false" exported="true" kind="src" path="/halfDuplexModbus"/> < classpathentry kind="src" path="src"/> < classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8"/> < classpathentry kind="lib" path="libs/jssc.jar"/> < classpathentry kind="lib" path="libs/pi4j-core.jar"/> < classpathentry kind="output" path="bin"/> < /classpath>

Please try with the newest version. Dependencies to other projects should be supported now.
