 Description   

I'm putting together some code that acts kind of like an application server.

I have a multi-project that defines:

  • a common runtime module (smash-runtime)
  • the main server module (smash-server)
  • a couple of example applications
  • the launcher module that puts everything together

The launcher copies the other projects dependencies to a particular file structure.

Mostly this is working great:

That's exactly the structure I want; apps/echo contains netty-echo.jar (my application) and its dependencies, apps/web contains web-client.jar and its dependencies.

smash-launcher/build.gradle is wonderfully concise:

description = "Bundle and launch a SMASH server."

configurations

{ boot echo web }

dependencies

{ provided project(":smash-runtime") boot project(":smash-server") echo project(":netty-echo") web project(":web-client") }

// Creates the Manifest Class-Path for provided dependencies, such as smash-runtime.
// Provided dependencies are needed by boot ("smash-server"), but are also available
// to applications.
def manifestClassPath() {
configurations.provided.files.collect { file -> "lib/${file.name}" }.join(" ")
}

jar {
manifest

{ attributes "Main-Class": "com.annadaletech.smash.SmashLauncher" attributes "Class-Path": manifestClassPath() }

}

task assembly(type: Copy) {
into "${project.buildDir}/server"
from jar

into("lib")

{ from configurations.provided }

into("boot")

{ from configurations.boot }

into("apps") {
into("echo")

{ from configurations.echo }

into("web")

{ from configurations.web }

}
}

My only issue is that when I've changed smash-runtime to have compile dependencies, those dependencies are NOT copied into the lib folder.

smash-runtime/build.gradle:

description = "Simple Minimal Application System Host - Runtime"

dependencies {
compile "org.slf4j:slf4j-api:${versions.slf4j}"
compile "log4j:log4j:1.2.17"
compile "org.slf4j:slf4j-log4j12:${versions.slf4j}"
}

I'm expecting to see the log4j.jar and friends in server/lib, but it is not present.

I get odd results using gradle dependencies:

I'm not seeing the transitive dependencies of smash-runtime, just the output jar. I really don't get it, because there's no real difference between smash-runtime and web-client, but for web-client I am getting the transitive dependencies.

My work around is create a new configuration, "hackRuntime", that extends from provided, and recapitulates the logging dependencies. That works, but I'm trying to figure out if there's a bug, or if I'm doing something wrong.

Comment by Peter Walker (Inactive) [ 15/Dec/12 ]

I suspect this "provided project(":smash-runtime")".
If you want to copy smash-runtime and all of its transitives, try "compile project(":smash-runtime")"

Comment by Szczepan Faber [ 12/Feb/13 ]

This is already fixed in the master and will be released with 1.5. Project dependencies resolved at configuration time now force the target project to get configured first. @Howard, I think the proper solution to the problem would be to make it lazy. For example, you could configure the jar task manifest in a doFirst action. This way, the resolution of the provided configuration would happen at execution time.

Hope that helps!
