Hi,

I´m trying to export org.eclipse.kura.driver.opcua.provider and I´m doing it the following way:
Export -> Plug-in Development -> Deployable plug-ins and fragments.

I´m getting the following error:
A cycle was detected when generating the classpath org.eclipse.kura.driver.opcua.provider_1.0.500.201906051912, org.eclipse.kura.core.configuration_2.0.300.201906051912, org.eclipse.kura.core_1.0.600.201906051912, org.eclipse.kura.core.configuration_2.0.300.201906051912.

I tried already the following:
* Windows -> Preferences -> Java-> Compiler -> Building -> Circular Dependencies --> changed from "error" to "warning"
* During the export the following checkbox is ticked "Allow for binary cycles in target platform"

I still didn´t find a way to fix it, can anyone please help? Thanks a lot in advance!

Hi,

I had the same problem with a driver that I was building. I didn't get to fix that, but I found some kind of "workaround":

I created a pom.xml file and I used maven to build the jar that I needed for the deployment package.

In this case you already have a pom.xml in the project, I believe.

To generate de jar I had to execute in a console or terminal:

mvn clean install -Dcheckstyle.skip

The -Dcheckstyle.skip due to some errors I got from maven checstyle.

Hope that helps.
