[stackoverflow] [progress Openedge Abl] Publish Something Else Than A Jar With Gradle To Nexus

[Lieven Cardoen]

I'm trying to use Gradle in combination with Ant to build our OpenEdge projects. OpenEdge is a 4GL language from some centuries ago. ;-)

Anyway, I've managed downloading some jar dependencies, but now I'm stuck in how to publish a PL file (Progress Library) to a Nexus repository. The thing is that like Maven, Gradle also seems to be made for Java projects.

This is my script (I also have a settings.gradle file with rootProject.name = 'stomp'):

apply plugin:'java'
apply plugin: 'maven-publish'

group 'be.mips'
version = '1.4.0-SNAPSHOT'

repositories {
/*
Gradle uses the same logic as Maven to identify the location of your local
Maven cache. If a local repository location is defined in a settings.xml,
this location will be used. The settings.xml in USER_HOME/.m2 takes precedence
over the settings.xml in M2_HOME/conf. If no settings.xml is available, Gradle
uses the default location USER_HOME/.m2/repository.
*/
mavenLocal()
maven {
credentials {
username '****'
password '****'
}
url "http://srv-ci-nexus:8082/nexus/content/repositories/MadeApplReleases/"
url "http://srv-ci-nexus:8082/nexus/content/repositories/MadeApplSnapshots/"
}
mavenCentral()
}

def stompProgressLibraryFile = file('dist/lib/STOMP.PL')

artifacts {
archives stompProgressLibraryFile
}

publishing {
publications {
mavenJava(MavenPublication) {
from components.java
artifact stompProgressLibraryFile
}
}

repositories {
maven {
// default credentials for a nexus repository manager
credentials {
username '****'
password '****'
}
// url to the releases maven repository
url "http://srv-ci-nexus:8082/nexus/repositories/snapshots"
}
}
}

configurations {
antconf
}

dependencies {
antconf 'be.mips:mips-progress-ant-tasks:1.5.8-SNAPSHOT',
'be.mips:mips-pct:1.0-SNAPSHOT',
'ant-contrib:ant-contrib:1.0b3'
}

/* Loads the jars */
ClassLoader antClassLoader = org.apache.tools.ant.Project.class.classLoader
configurations.antconf.each {
File f -> antClassLoader.addURL(f.toURI().toURL())
}

/* Extend clean task */
clean.doFirst {
delete '_ant_rcode', 'src', 'dist'
println 'deleted directories'
}

/* Create dist/lib directory as prolib does not create directory automatically */
task init(dependsOn: clean) {
doLast{
project.file('dist/lib').mkdirs()
println 'created dist/lib'
}
}

ant.importBuild 'build.xml'


Running gradle publish gives me next output:

The first thing I notice is having these java tasks that I do not need. :compileJava, rocessResource, :classes, :jar ...

Basically I had a build.xml ant file doing everything I wanted. But the dependency management in ant is very poor. So I decided to use Gradle in combination with Ant. I want Gradle to do the dependency management for me. So far downloading dependencies seems to work fine (will have to try with a PL instead of a jar). But publishing something else than a jar, how do you do that?

Read a lot of the Gradle Online Documentation, but all the examples seem to be based on java.
