createMissingPackageInfoClass support / can't compile josm

[brycenesbitt]

With:

java -version
java version "1.7.0_65"
Java(TM) SE Runtime Environment (build 1.7.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)

I can't compile current josm, without removing createMissingPackageInfoClass=False
from build.xml (near line 218). The error message is:

javac doesn't support the "createMissingPackageInfoClass" attribute

Please use at least ant ​1.8.3.

I am using 1.8.4 but still I get above error message

Most likely you still have set ANT_HOME to the old version 1.8.2.

Uninstall the WinAnt (this is a very old ant, I guess you installed this on your Windows) and unzip the 1.9.7 from:
​http://archive.apache.org/dist/ant/binaries/apache-ant-1.9.7-bin.zip
to any dir. Write then this path into a new var "ANT_HOME" in your environment variables and try again.
Or do on commandline:
SET ANT_HOME=C:\your\path\to\unzipped\ant\folder
and run ant after.

But it will install with 1.8.2 as well if you just delete all entries of createMissingPackageInfoClass="false" in the build.xml, same thing.
