This build output contains diagnostics which are no longer produced by the build.xml script in the derby trunk. For instance, java15compile.classpath is no longer a build setting--that is because the trunk requires JDK 8 or higher and the derby build no longer produces byte code that runs on older java versions.

Hope this helps,

Hello,
I encountered a problem in building the project with the command 'ant -quiet buildsource’. I already have installed maven. And the command 'ant -quiet clobber’

It says;
[setJdkProperties] Unrecognized VM vendor: 'Oracle Corporation'
[setJdkProperties] An attempt to configure the required JDKs will be made, but the build may fail.
[setJdkProperties] In case of problems:
[setJdkProperties]- consult BUILDING.html and set the required properties manually [setJdkProperties]- set the property printCompilerProperties to true and ask the Derby development community for help
[setJdkProperties](please provide the debug output from running ant)

BUILD FAILED
/Users/kavinranawella/10.8/build.xml:252: Don't know how to set java15compile.classpath, java16compile.classpath using this environment:

java.vendor = Oracle Corporation
java.home = /Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/jre
java.version = 1.8.0_121
os.name <http://os.name> = Mac OS X
j14lib = null
j15lib = null
j16lib = null
jdkSearchPath = /Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents

Please consult BUILDING.html for instructions on how to set the compiler-classpath properties.

Can you help me with this. I think this is an issue with my OS (OS X 10.12.6 ).

Thank you.
