This page describes how to compile the Java source code in IDE in order to get a runnable
Getting the Source
Compiling using Ant
The easiest way to compile JOSM
Compiling using Eclipse
Download and install Eclipse: https://www.eclipse.org/
Use Eclipse and the provided
.classpath file. Just import project using the JOSM core folder as root directory.
You will have problems compiling, due to problems compiling Mappaint MapCSS with a fresh install of Eclipse. First you will need the JavaCC plugin for Eclipse. To install it in Eclipse, go to Help->New Software... then add the site http://eclipse-javacc.sourceforge.net/ as a source, and install the JavaCC Eclipse Plug-in. Then in the Package Explorer, expand org.openstreetmap.josm.gui.mappaint.mapcss, right-click on MapCSSParser.jj, and "Compile with JavaCC". This should put new java files in a package called org.openstreetmap.josm.gui.mappaint.mapcss.parsergen, but if it doesn't, you will have to create the package manually (right-click and create package), then drag the new files into the package you just created (they should be easy to identify based on the light gray text that denotes it was compiled from MapCSSParser.jj). This should resolve any import issues in MapCSSStyleSource.java, and you should now be able to compile JOSM.
If you try to compile the JOSM sources in Eclipse and get errors like "The method marktr(String) is undefined for the type SomeType" look at solution suggested at mailing list.
Compiling using Netbeans
- Download and install Netbeans: https://netbeans.org/
- File → Open Project
- Navigate to the JOSM source code (see #GettingtheSource), subdirectory
2to clean and compile, and
3to run JOSM:
Compiling using IntelliJ IDEA
It is most convenient, to run tests from an IDE like Eclipse or Netbeans. There is also an ant task to run all tests (but you cannot rerun individual tests).
All unit tests can be run in headless mode (i.e, without a graphic display), allowing them to be run in continuous integration projects.
Running Test from Command line
Here are some of the tools you will need for installing under most linux operating systems. Tools: ant, java jdk/jre 8, junit Example install for Ubuntu Linux:
sudo apt-get install ant openjdk-8-jdk junit # please install these ahead, you definitely need them
The quickest way to run the tests is done using the 'ant' build system.
ant clean test # this will run through all 200+ tests marking them sucessful, failure, in error, or skipped.
You can run individual tests from the command line, as well. Include all libraries in the class path like this:
export TESTCP=".:test/unit:test/functional:dist/josm-custom.jar:test/lib/fest/*:test/lib/junit/*:test/lib/*:test/lib/unitils-core/*" export TESTCP=$TESTCP:"tools/*:tools/findbugs/*" # added these missing directories. Without it will fail to run.
Here are a few build and run instructions for some example tests:
# Projections Reference Test javac -cp $TESTCP test/unit/org/openstreetmap/josm/data/projection/ProjectionRefTest.java java -cp $TESTCP org.junit.runner.JUnitCore org.openstreetmap.josm.data.projection.ProjectionRefTest # Download GPS Task Test javac -cp $TESTCP test/unit/org/openstreetmap/josm/actions/downloadtasks/DownloadGpsTaskTest.java java -cp $TESTCP org.junit.runner.JUnitCore org.openstreetmap.josm.actions.downloadtasks.DownloadGpsTaskTest
On Windows the syntax is almost the same:
set TESTCP=".;test/unit;test/functional;dist/josm-custom.jar;test/lib/fest/*;test/lib/junit/*;test/lib/*;test/lib/unitils-core/*;tools/*;tools/findbugs/*" javac -cp %TESTCP% test/unit/org/openstreetmap/josm/data/projection/ProjectionRefTest.java java -cp %TESTCP% org.junit.runner.JUnitCore org.openstreetmap.josm.data.projection.ProjectionRefTest # and similar for the Download GPS Task Test javac -cp %TESTCP% test/unit/org/openstreetmap/josm/actions/downloadtasks/DownloadGpsTaskTest.java java -cp %TESTCP% org.junit.runner.JUnitCore org.openstreetmap.josm.actions.downloadtasks.DownloadGpsTaskTest
