Re: How to build Jython standalone jar from source code

Dear jim,

I have built Jython standalone jar for version 2.7.1b2 succesfully using 'ant all-jars' command with Java 7. But I still have below problem with newest Jython version. 

I am developing MeteoInfoLab software using Java and Jython (as script language). It's ok to initialize Jython when the directory path only includes ASCII characters. But the initialization will be failed if the path includes non-ASCII characters (in my case is Chinese characters).  The error message shows: java.lang.IllegalArgumentException: Cannot create PyString with non-byte value. The issue 2331 said it has been solved in 2.7.1b2 (http://bugs.jython.org/issue2331) , but the problem is still there from my test. I also mentioned that a comment report same problem in github (https://github.com/jythontools/jython/commit/c61eaefb774cdb174472265d3c27fc5b87febd34).

The detailed error message:

Yaqiang,

Check out the source from https://hg.python.org/jython or the mirror at https://github.com/jythontools/jython

You can build from source by using this ant target:

all all-jars

The standalone jar is in dist/jython-standalone.jar

Please note that due to the use of an older version of Antlr, building is only currently supported on Java 7; but built jars will run on Java 7, 8, or 9. (Taking into account this limitation with Java 9: http://bugs.jython.org/issue2362)

Hope this helps!

- Jim
