    Edison with Mraa/Java/Maven

    2trc

      Hi,

       

      I've been trying some of the java examples from mraa and they work. I had a look at this tutorial "Blinking an LED with Java on the Intel Edison " and this relevant question (from Galileo community) "MRAA with Java".

       

      Now my problem is that whenever I compile/build the same examples with maven (executable jar with dependencies included), I get this error:

      Provide an int arg if you want to flash on something other than 8

      Exception in thread "main" java.lang.ExceptionInInitializerError

              at mraa.Gpio.<init>(Gpio.java:47)

              at BlinkIO.main(BlinkIO.java:57)

      Caused by: java.lang.NullPointerException

              at mraa.mraaJNI.<clinit>(mraaJNI.java:305)

              ... 2 more

       

      I've included the mraa dependency in my pom.xml

      <dependency>

                              <groupId>io.mraa</groupId>

                              <artifactId>mraa</artifactId>

                              <version>1.5.1</version>

      </dependency>

       

      Am missing something else?

       

      Thanks in advance!

       

      Remi
