Thanks Daniel,
Your suggestion worked. Moved the Java.classpath to just after the
module declaration and Buildr began downloading the artifact
My extension now looks like this:
module DDLExporter
include Extension
Java.classpath << "org.hibernate:hibernate-tools:jar:3.2.3.GA"
first_time do
.....
Regards,
Ijonas.

The problem is actually that you haven't invoked Java.load. More
importantly, even if you did perform the invocation, it has probably
been
invoked previous to that point in the code (when the task is
executed),
meaning that your classpath additions will not be recognized. Try
sticking
the Java.classpath mutations somewhere in the static scope. They
should be
executed when your extension is *loaded*. Then, invoke Java.load
within the
task just before you call the Hibernate class.
Rule of thumb: add to classpath as *early* as possible, invoke load
as *late
* as possible.

Hi,
I'm trying to write a extension that exports DDLs using HIbernate's
schemaexport tool. Although I've added the hibernate-tools
dependency to the
Java.classpath I don't see it downloading the jar and my .m2/
repository
remains empty of the Hibernate Tools jars.
I've got the following fragment of code in my extension which does
all the
heavy lifting:
Rake::Task.define_task 'ddl' do |task|
puts "classpath 1: #{Java.classpath}"
Java.classpath << "org.hibernate:hibernate-tools:jar:3.2.3.GA"
puts "classpath 2: #{Java.classpath}"
Java.load
puts "classpath 3: #{Java.classpath}"
puts Java.java.lang.String.new("hello there")
config_file = Java.java.io.File.new(config_file_path)
puts config_file.canonicalPath
config = Java.org.hibernate.cfg.Configuration.configure
(config_file)
# config = nil
schema_export =
Java.org.hibernate.tool.hbm2ddl.SchemaExport.new(config)
schema_export.outputFile = output_filename
schema_export.execute(true, true, false, false)
end
Producing the following output
** Execute ContentMigrator:ddl
classpath 1:

The classpath isn't resolved properly by the looks of things and
hence the
build fails.
Is Java.classpath << "org.hibernate:hibernate-tools:jar:3.2.3.GA" the
right way of adding a dependency for my extension ? If so, what am
I doing
wrong ?
Many thanks,
Ijonas.
