I'm trying to get a custom task working in the default docker image. Basically I used this
https://github.com/hbelmiro/jbpm-work-item-handler-demo
project adapted the Version to 7.73.final. I then ran maven install and uploaded the custom task via Settings -> "Add Custom Task" in the UI, and set it to "On"
After this I installed the custom task in my space under Settings -> Custom Task and Added the dependency under Dependencies using "Add from repository". When I now want to deploy this using the "Deploy" button I get an exception ERROR [org.kie.scanner.MavenClassLoaderResolver] (default task-30) Dependency artifact not found for: de.piu.datenhaus:addressvalidation:1.1
this is the JAR file however which I uploaded and which is my actual Custom Task (Work Item handler)
How I can solve this issue? I found nothing related to this in the docs or by googling.
This is how the custom task assets preferences looks like:
[
[
"name" : "DatenhausAddressSignature",
"displayName" : "DatenhausAddressSignature",
"category" : "addressvalidation",
"description" : "",
"defaultHandler" : "mvel: new de.piu.datenhaus.addressvalidation.DatenhausAddressSignatureWorkItemHandler()",
"documentation" : "addressvalidation/index.html",
"parameters" : [
"DatenhausAddress" : new StringDataType()
],
"results" : [
"DatenhausAddressSignature" : new StringDataType()
],
"mavenDependencies" : [
"de.piu.datenhaus:addressvalidation:1.1"
],
"icon" : "DatenhausAddressSignatureWorkItemHandler.png"
]
]

This issue can be worked around by adding -SNAPSHOT to the version tag in the pom.xml. I tried this even on a fresh install, which I installed using the installer, got the same error when I do not append -SNAPSHOT to the version.
This is weired and I do not know how or where to further track down the issue. Maybe someone else has an additional explanation
Further found out that it only happens if the project is build with a java 1.8 version
