I'm not sure if this is a splitter problem or OS problem but I thought I'd ask here first as I think that this problem is likely to have started with r570 (http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2017q1/025847.html). The following has been tried on both openSuSE 13.2 and 42.2 I checked out the latest splitter into an empty directory, ran "ant dist" and received an error regarding junit.jar. I then installed ant-junit and now when running "ant dist" I get resolve-test: compile.tests: [javac] Compiling 13 source files to /home/bos/Maps/tile-splitter/splitter/build/test-classes run.tests: [junit] Running uk.me.parabola.splitter.AreaSetTest [junit] Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 0.042 sec [junit] TEST uk.me.parabola.splitter.AreaSetTest FAILED [junit] Running uk.me.parabola.splitter.ConvertTest [junit] Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 0.006 sec [junit] TEST uk.me.parabola.splitter.ConvertTest FAILED [junit] Running uk.me.parabola.splitter.RoundingTest [junit] Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 0.002 sec [junit] TEST uk.me.parabola.splitter.RoundingTest FAILED [junit] Running uk.me.parabola.splitter.geo.CityFinderTest [junit] Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 0.003 sec [junit] TEST uk.me.parabola.splitter.geo.CityFinderTest FAILED [junit] Running uk.me.parabola.splitter.tools.CustomCollectionsTest [junit] Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 0.005 sec [junit] TEST uk.me.parabola.splitter.tools.CustomCollectionsTest FAILED [junit] Running uk.me.parabola.splitter.tools.SparseBitSetTest [junit] Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 0.002 sec [junit] TEST uk.me.parabola.splitter.tools.SparseBitSetTest FAILED [junit] Tests FAILED [junitreport] Processing /home/bos/Maps/tile-splitter/splitter/tmp/TESTS-TestSuites.xml to /tmp/null380785018 [junitreport] Loading stylesheet jar:file:/usr/share/java/ant/ant-junit.jar!/org/apache/tools/ant/taskdefs/optional/junit/xsl/junit-frames.xsl [junitreport] Warning: org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser: Property 'http://javax.xml.XMLConstants/property/accessExternalDTD' is not recognized.
