Scott Carey commented on AVRO-318:
----------------------------------
bq. The Java 5 stuff is just a requirement of Forrest. No way around it.
As in Forrest won't build without Java5 -- Java6 breaks it? or as in that
env.variable must be set?
If the latter, just have the script check to see if the env var is set, and if
not then set it locally to
{noformat}
/System/Library/Frameworks/JavaVM.framework/Versions/1.5/Home/
{noformat}
which on all recent Macs should be a symlink to either an actual java 1.5, or
1.6 if that doesn't exist.
bin/java is contained within.
On Snow Leopard (OSX 10.6) there is no Java 5, only Zul... err Java 6.
Snow Leopard's java version mapping directory looks like this:
{noformat}
$ ls -lh /System/Library/Frameworks/JavaVM.framework/Versions/
total 64

> Build.sh cleanup: md5/sha1 on Mac OS X, don't fail hard if build/ exists, and
> play nice with Forrest

> Key: AVRO-318
> URL: https://issues.apache.org/jira/browse/AVRO-318
> Project: Avro
> Issue Type: Bug
> Components: build
> Reporter: Jeff Hammerbacher
> Priority: Blocker
> Fix For: 1.3.0
>
>
> I encountered three problems when trying to build Avro today (via "./build.sh
> dist) to test interop:
> * md5sum and sha1sum do not exist on Mac (md5 is the replacement for the
> former)
> * If "build/" exists, you fail hard with "mkdir: build: File exists"
> * If you don't have Java 5, Forrest fails with "'java5.home' is not defined.
> Forrest requires Java 5." and other good stuff.
