Hello, I am new to this list (although a long time OSM mapping contributor).
I am trying to develop a JOSM plugin following the steps here[0]. I was able to successfully (I think - I didn't notice any error messages) check out the plugin environment into an empty directory called josm per the instructions (specifically /home/<my username>/josm However, when I attempt: $ cd josm/core $ ant to compile josm core, I get the following message: [ivy:resolve] :::::::::::::::::::::::::::::::::::::::::::::: [ivy:resolve] :: UNRESOLVED DEPENDENCIES :: [ivy:resolve] :::::::::::::::::::::::::::::::::::::::::::::: [ivy:resolve] :: org.jacoco#org.jacoco.ant;0.8.6-SNAPSHOT: not found [ivy:resolve] :::::::::::::::::::::::::::::::::::::::::::::: I am running Ubuntu 16.04.7 LTS I tried $ sudo apt update $ sudo apt upgrade And then retried the compile. However, I got the same message. I tried: $ ant -v But even with the verbose switch, I didn't notice any additional information that was helpful. A couple of years ago I was able to develop a plugin (nothing worthy of release to the community, but at least it ran and showed a dialog with "Hello World"). Since JOSM has changed a lot in that time, I completely removed that JOSM environment, and started over. Any help would be greatly appreciated. Thanks, Mike [0] https://josm.openstreetmap.de/wiki/DevelopersGuide/DevelopingPlugins
