Description

If a java file is in default package, buildr will recompile it only if it changes. If a java file is in a named package, buildr will recompile it everytime, even when unecessary.

= Example 1 (default package) =

File src/main/java/Hello.java

<buildfile>
define 'buildr_nopackage' do
project.version = '1.0'
package(:jar)
end
</buildfile>

$ buildr compile
(in /home/lacton/workspace/buildr_nopackage, development)
Compiling buildr_nopackage
Compiling buildr_nopackage
Completed in 0.715s
$ buildr compile --trace
(in /home/lacton/workspace/buildr_nopackage, development)

There is no compilation at all on the second call, as expected.

= Example 2 (named package) =

File src/main/java/mypackage/Hello.java

<buildfile>
define 'buildr_package' do
project.version = '1.0'
package(:jar)
end
</buildfile>

Hello.java was recompiled and the file target/classes/mypackage/Hello.class was written once more, with a new timestamp, although nothing changed between the two compilation.
