Java 1.6 is not supported anymore by ant

[markodraisma]

Someone asked me to help with a CMME file. It still works after some fiddling: I cloned the lot locally, edited the build.xml file to exclude the certificate part (not needed locally), and used source 1.7 instead of 1.6.

ant -buildfile build.xml compile
ant -buildfile build.xml dist-viewer
ant -buildfile build.xml dist-editor

Now I can run the applets using the .bat files.

On Ubuntu 20.04:

• install OpenJDK (I used openjdk-8, the oldest available) and ant
• remove the 4 lines with the signjar element from build.xml
• ant
• you need to be running a GUI display server; I'm running Xorg
• now java -jar dist/CMME-Editor.jar and java -jar dist/CMME-Viewer.jar both work

Both applications support exporting to MusicXML. I tried this on two scores, then fed the results to musicxml2ly (trying various options) and lilypond to create PDFs. They are unusable.

Wishes:

• fix the MusicXML produced to render sensibly with LilyPond (I've never looked at MusicXML, it would help to have someone who has) - meanwhile, the application's own PDF export works fine
• a separate command line application cmme2musicxml.jar, to perform just the format conversion
• for the CMME site to point to this repository
