Hi everyone,

I am starting a proof of concept for rules engine usage, and I tried the latest released docker.

The install and setup is going fine, but as soon as I try to add a new project, I have an error message.

I can see the following in the logs :

13:51:07,464 INFO [org.jboss.as] (Controller Boot Thread) WFLYSRV0025: WildFly Full 14.0.1.Final (WildFly Core 6.0.2.Final) started in 52844ms - Started 858 of 1091 services (397 ser

For the first error, I could find Jira's about it (https://issues.jboss.org/browse/RHDM-732), but it does not apply for WAR packaged version running into Docker.

I tried to fix it, but

a) I could not find any local maven instance running, so I cannot really set a value for the m2repo.url

b) I customiser Dockerfile to include Maven2 and environment variable (M2_HOME, M2, ...), but it does not resolve the issue.

I suppose that the second error is linked to the first one...

Finally, I also noticed to have this issue when I use the Showcase version, and I use the samples projects...

If anyone has any clue how to fix this, please let me know.

Thank you

Hi Stefan,

There is high probability that you have set up wrongly M2_HOME or the bin location is not in your Path.
