ant spotbugs gives NoClassDefFoundError: org/slf4j/LoggerFactory

[GerdP]

Tried to run ant spotbugs on josm core or plugin pbf.

I've downloaded c:\Users\Gerd\Downloads\slf4j-1.8.0-beta2.zip from ​https://www.slf4j.org/download.html
and extracted slf4j-api-1.8.0-beta2.jar. After copying this into the two spotbugs directories
ant spotbugs works again:

Should I commit this?

[GerdP]

Same problem on Jenkins, see https://josm.openstreetmap.de/jenkins/job/JOSM-Plugins/jdk=JDK8/1476/console

In 14702/josm:

fix #17206 - add missing files for Spotbugs 3.1.10 (regression from r14604)

[GerdP]

Thanks, seems to work again. One more question: How do I configure a sonarlint Eclipse plugin to produce the same results as those that are presented by Jenkins?

[Don-vip]

See ​https://www.sonarlint.org/eclipse/#eclipse-connected-mode You need to tell the Eclipse plugin the URL of our SonarQube instance.

[GerdP]

If I got that right I need a login to SonarQube for that. I tried with my Trac user+password but that did not work.
