Description

When Buildr.options.parallel=true

If two projects start executing a junit test task at the same time they fail with:

Test framework error: uninitialized constant Antwrap::AntProject
or
Test framework error: uninitialized constant Antwrap::AntProject::Main
or
wrong # of arguments(0 for 1) for using

–
the problem is in ant.rb
in the method def ant(name, &block)

synchronizing the method fixes the problem.

my buildfile:
VERSION_NUMBER = "1.0.0"
GROUP = "bu"
COPYRIGHT = ""

repositories.remote << "http://repo1.maven.org/maven2/"
repositories.remote << "http://www.ibiblio.org/maven2/"

Buildr.options.parallel=true

desc "The Bu project"
define "bu" do

project.version = VERSION_NUMBER
project.group = GROUP
manifest["Implementation-Vendor"] = COPYRIGHT

define "sub1" do
package(:jar)
end

define "sub2" do
package(:jar)
end
end

my layout:
.
./sub1
./sub1/src
./sub1/src/test
./sub1/src/test/java
./sub1/src/test/java/TestClazz.java
./sub1/src/main
./sub1/src/main/java
./sub2
./sub2/src
./sub2/src/test
./sub2/src/test/java
./sub2/src/test/java/TestClazz.java
./sub2/src/main
./sub2/src/main/java
./buildfile

and TestClazz.java is:
import org.junit.*;

public class TestClazz {
@Test
public void testMethod() throws Exception {
}
}
