Just getting started learning how to write a Java extension to libreoffice (on Debian fwiw).
--- <total aside> I find Eclipse and https://github.com/smehrbrodt/libreoffice-starter-extension.git and https://github.com/LibreOffice/loeclipse.git to be overly opaque and hard to fathom for my liking (I've had to live on command lines a lot, and this environment seems generally more debuggable and controllable (got stuck moving a class around in the first project above)), --- </total aside> so the raw LO sdk is what I'm trying to ride now. Got stuck needing a simple fix, for the following bug: $ ... set up LO sdk as per ./setsdkenv_unix ... $ cd sdk/examples/DevelopersGuide/FirstSteps $ make FirstStepsExamples ... $ make FirstUnoContact.run "/usr/bin/java" -Dcom.sun.star.lib.loader.unopath="/opt/l/libreoffice/program" -jar /home/me/lo/llo/out/libreoffice5.2_sdk/LINUXexample.out/class/FirstStepsExamples/FirstUnoContact.jar Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/star/lib/loader/Loader$1 at com.sun.star.lib.loader.Loader.getCustomLoader(Loader.java:177) at com.sun.star.lib.loader.Loader.main(Loader.java:127) Caused by: java.lang.ClassNotFoundException: com.sun.star.lib.loader.Loader$1 at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 2 more make: *** [FirstUnoContact.run] Error 1 Makefile:96: recipe for target 'FirstUnoContact.run' failed So this is a simple problem, the makefile includes most required files into the jar file, but not the missing "com/sun/star/lib/loader/Loader$1.class" The current settings/std.mk recipe includes each required file from the same directory, one by one, but omits this one. Just adding all the files from that dir (which are all needed to be in the jar file) is better (will catch any additions/ removals in future versions automatically). Here's the git diff patch which makes things work properly: diff --git a/settings/std.mk b/settings/std.mk index 9fe1e79..ac2d4aa 100644 --- a/settings/std.mk +++ b/settings/std.mk @@ -82,12 +82,5 @@ JAVAMAKER="$(OO_SDK_HOME)/bin/javamaker" REGMERGE="$(OO_SDK_URE_BIN_DIR)/regmerge" SDK_JAVA_UNO_BOOTSTRAP_FILES=\ - -C $(CLASSES_DIR) $(SQM)com/sun/star/lib/loader/Loader.class$(SQM) \ - -C $(CLASSES_DIR) $(SQM)com/sun/star/lib/loader/Loader$$Drain.class$(SQM) \ - -C $(CLASSES_DIR) $(SQM)com/sun/star/lib/loader/Loader$$CustomURLClassLoader.class$(SQM) \ - -C $(CLASSES_DIR) $(SQM)com/sun/star/lib/loader/Loader$$Drain.class$(SQM) \ - -C $(CLASSES_DIR) $(SQM)com/sun/star/lib/loader/InstallationFinder.class$(SQM) \ - -C $(CLASSES_DIR) $(SQM)com/sun/star/lib/loader/InstallationFinder$$StreamGobbler.class$(SQM) \ - -C $(CLASSES_DIR) $(SQM)com/sun/star/lib/loader/WinRegKey.class$(SQM) \ - -C $(CLASSES_DIR) $(SQM)com/sun/star/lib/loader/WinRegKeyException.class$(SQM) \ + -C $(CLASSES_DIR) $(SQM)com/sun/star/lib/loader/$(SQM) \ -C $(CLASSES_DIR) $(SQM)win/unowinreg.dll$(SQM) If you need a different format, for this or future patches, please let me know. NOTE: Currently I'm just working in a local lo sdk directory created from the distribution tar file. I intend to clone a full sdk repo when I have adequate network access to do so. IN OTHER WORDS, the git hashes above are most likely incorrect/ not related to the actual repo - please tell me how to create a "repo neutral" patch.
