Parallel import: ClassNotFoundException: org.jboss.resteasy.client.jaxrs.internal.proxy.ProxyBuilderImpl

[gim-]

Current Behavior

When I add --import.parallel=true argument, the keycloak-config-cli fails right at the start.

Command example:

java -jar keycloak-config-cli-22.0.4.jar  --import.cache.enabled=false --import.parallel=true \
  --keycloak.url='http://localhost:8080' \
  --keycloak.user='admin' \
  --keycloak.password='admin' \
  --import.files.locations='./config/*' \
  --import.var-substitution.enabled='true'

Output:
