SOLVED: add jSerialComm maven artifact to extension --> NoClassDefFoundError

[u-u-u]

Hi, i try to include an external .jar into a Bitwig extension to use serial communication between an Arduino microcontroller.

Then I added the maven artifact to the pom.xml file like this:

Code: Select all

<dependencies>
	<dependency>
		<groupId>com.bitwig</groupId>
		<artifactId>extension-api</artifactId>
		<version>7</version>
	</dependency>
	
	<dependency>
		<groupId>com.fazecast</groupId>
		<artifactId>jSerialComm</artifactId>
		<version>2.4.0</version>
	</dependency>
</dependencies>

When building the project in Eclipse, maven seems to download the .jar file and in the project explorer it looks like this:

Now I include a class from that .jar file into the extension, e.g.:

Code: Select all

import com.fazecast.jSerialComm.SerialPort;

...and use it in the extension:

Code: Select all

48   SerialPort bla = SerialPort.getCommPort("COM5");
49   host.println(bla.getSystemPortName());

But after installing the Bitwig extension (using the maven install command), I get the following error message:

What can I do about that?

You need to use the shade plugin to put all necessary class files into one big jar, which is then renamed to bwextension.
See the DrivenByMoss POM for an example:

Thank you, that worked fine!
