Hi,
I have a simple groovy project with sources in src/main/groovy. Lets
say they are all in a package called 'foo'.
If I run compileGroovy without any additional configuration the
classes end up in
build/classes/main/foo/
why is the main in there ?
Because they're the classes for the 'main' source set. The classes
directory for the 'test' source set is build/classes/test, and so on.
You can change these default locations if you like. For example:
sourceSets.main.classesDir = file('build/main-classes')
sourceSets.test.classesDir = file('build/test-classes')
Probably best not to point them at the same directory.
Also - how can I run a class from a build.gradle ?
this is my build.gradle:
apply plugin:'groovy'
buildscript{
apply {
apply from:
'http://myserver:port/artifactory/repo/de/configuration/1.0/configuration-1.0.gradle'
}
}
dependencies {
groovy group:'org.codehaus.groovy', name:'groovy-all', version:'1.7.4'
}
task 'run-project' << {
new foo.AGroovy()
}
I assumed that per default if the compiled class is in build/classes
it will run. But also if the compiled class is under
build/classes/foo/AGroovy.class running 'gradle run-proejct' fails
with 'unable to resolve....'
What do I have to configure to run from a build script ?
There's a few options.
If the class is only used at build time, you can move it to the
buildSrc/src/main/groovy directory, and Gradle will automatically
compile it and make it available in the build script, like you're trying
to do above. Nothing more to configure there.
If it's a production class, you might use the JavaExec task, but this
requires a class with a main() method:
task 'run-project'(type: JavaExec) {
main = 'my.mainClass'
classpath = sourceSets.main.runtimeClasspath
args = ['some', 'args']
}
Another option is to make use of Groovy's dynamic nature and load the
class up after it has been compiled:
task 'run-project' {
dependsOn sourceSets.main.runtimeClasspath
doLast {
def cl = new
URLClassLoader(sourceSets.main.runtimeClasspath.collect
{it.toURI().toURL() } as URL[])
def myClass = cl.loadClass('my.mainClass').newInstance()
// do some stuff with myClass
}
}
