Build issues on Windows 10

[AMillionReasons]

I'm trying to build ohNet from the master current at the time of raising this issue. On Windows 10, with the ultimate aim of getting Android libraries for an app I'm developing. I've hit a few of problems with the build. This is the first time I've tried to build ohNet, so I apologise if these are caused by not having a correct build environment.

I get a python error. I have Python 3.8 and I assuming this is because print changed to a function and I can bracket 'print' calls in bundle-binaries.py to fix this.

python bundle_binaries.py --system Windows --architecture x86 --configuration Release
File "bundle_binaries.py", line 124
print "Too many arguments."

Trying to build java bindings on Windows 10 using jdk11.02 I get errors. I removed -Xbootclasspath entries from javac commands to get the build through.

        "C:\Program Files\Java\jdk-11.0.2\bin\javac.exe" -classpath OpenHome\Net\Bindings\Java\ -d Build\Obj\Windows\Release\ -Xbootclasspath:"C:\Program Files\Java\jdk-11.0.2/jre/lib/rt.jar" -target 1.6 -source 1.6 OpenHome\Net\Bindings\Java\org/openhome/net/controlpoint/Argument.java

Stop.

Building the ohNetAndroidNative target I get the following error. I'm assuming that in this case cp should be copy. I'm not sure where or how best to fix this particular issue.
