Maven Central: missing dependencies

[jannvck]

When using swrlapi-drools-engine 1.1.3 in SBT, I get unresolved dependencies which are not found:

• org.drools#drools-osgi-integration;6.4.0.Final
• org.drools#knowledge-api;6.4.0.Final

I have tried several former versions of swrlapi-drools-engine which are all affected by these missing dependencies as well.

Both dependencies are on Maven Central. I am pretty sure SBT also uses Maven Central for artifact resolution so I am not sure what is going on.

Can you build the 1.1.2 version of the SWRLAPI project as per instructions here:

[jannvck]

Thank you for your answer.
I also saw that they are on Maven Central, but anyways resolution fails for some reason ("not found").
Maybe it's an SBT specific problem, I have not tried other build tools.

I will try building the 1.1.2 version tomorrow!

The build fails while trying to execute mvn clean install in swrlapi-project folder:

My mistake. Remove the following line from the POM:

<module>../swrlapi-builtin-library-example</module>

I will try to get a new release out soon that fixes this.

There's somehow more progress but in the end there's still some error:

[martinjoconnor]

You can ignore for the moment. I am running the tests in parallel and the non-thread-safe Date and DateFormat classes used by the temporal built-ins can generate this error.

I plan to fix this issue.

[jannvck]

I don't see how this is related to the SBT problem.
Do you have any idea why the dependency resolution fails?

EDIT:

As the build was successful with maven I think this is a SBT related issue and can therefore be closed.
It might be related to this issue: sbt/sbt#1690

Trying to remove the ~/.sbt and ~/.ivy2 folders and reinstalling SBT 0.13.13 made no difference.
