Dear Gradle friends,
It's been a very long time for me since I've been involved with
Gradle. You've been doing a fantastic job over the past couple of
months and the result is just stunning.
I've gotten hooked - again - to Gradle and started playing with it for
fun and self-education. Right now I'm trying to port Spring from Ant
to Gradle but I've run into some compile weirdnedd. This is why I'm
seeking your help. I'm using Gradle 0.8.
I won't lay out the details of my entire setup, it's Gradle so it's
pretty simple. I've uploaded a zip file containing the spring source
and my build logic for those of you interested here:
http://drop.io/29t58yo (48Mb)
The crux of the matter is this: I've added a project spring-beans
which gets its source code from the big spring src/ directory.
Normally my build file for spring-beans looks like this:
compileJava {
source = fileTree {
from src_dir
include "org/springframework/beans/**"
exclude "org/springframework/beans/factory/aspectj/**"
}
}
dependencies {
compile project(':src:spring-core')
compile ':cglib-nodep-2.1_3'
}
Pretty basic stuff, only it doesn't work. What happens, and you can
try this yourself ("gradle clean build upload" from the project root),
is that CompileJava is trying to compile files from the
org.springframework.core package which it shouldn't touch and for
which it is missing JARs on the class path.
I've changed my build file as follows and this does work:
compileJava.doFirst {
def temp_src_dir = file('build/temp/src')
temp_src_dir.mkdirs()
copy {
from src_dir
into temp_src_dir
include "org/springframework/beans/**"
exclude "org/springframework/beans/factory/aspectj/**"
}
}
compileJava {
source = fileTree('build/temp/src')
}
dependencies {
compile project(':src:spring-core')
compile ':cglib-nodep-2.1_3'
}
Works but doesn't look as slick. I'm at a loss to explain why the
normal case doesn't work and why separating the intended code does
work. The only thing I can think of is that the compiler first checks
the source folder for classes it needs and only afterwards the class
path. Is this a known problem?
Yes. That's exactly what javac does.
To workaround the problem, you can use an empty sourcepath:
compileJava {
options.compilerArgs = ['-sourcepath', '']
}
I've checked the issues in JIRA but nothing jumped me in the eye.
I've added http://jira.codehaus.org/browse/GRADLE-689
It's fixed in trunk.
