------------------------------------

             Summary: Document use of JCC_JDK
                 Key: PYLUCENE-40
                 URL: https://issues.apache.org/jira/browse/PYLUCENE-40
             Project: PyLucene
          Issue Type: Improvement
            Reporter: Ryan J Ollos
         Attachments: jcc_build_output.txt

I found two issues when trying to [help someone on Stack Overflow|https://stackoverflow.com/questions/48711714/] build the library. First, the [documentation on PyPI|https://pypi.python.org/pypi/JCC/] states:
{quote}JCC’s setup.py file needs to be edited before building JCC to specify the location of the Java Runtime Environment’s header files and libraries.
{quote}
However, it appears you have a better mechanism of setting {{JCC_JRE}}, but it's not documented.

Second, when setting {{JCC_JRE}} is appears to work correctly and use the path to the specified {{JCC_JRE}} in the compilation, but the first line of output might indicate that a different JRE is being used:
{code:java}
$JCC_JDK=/Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home python setup.py install
found JAVAHOME = /Library/Java/JavaVirtualMachines/jdk1.8.0_141.jdk/Contents/Home
found JAVAFRAMEWORKS = /System/Library/Frameworks/JavaVM.framework
...
{code}
So maybe the found {{JAVAHOME}} should not be printed if {{JCC_JRE}} is set, so it appears that {{JCC_JRE}} is successfully overriding the {{JAVAHOME}}. I'll attach the full output from building on my platform.
