Copy all dependencies from one Gradle configuration to another - gradle

I'd like to copy all Gradle dependencies from one configuration to another. Specifically I'd like to copy everything in compile to jmh.
I have found that I can get this to work with the following:
configurations {
compile.dependencies.each {
jmh.dependencies.add(it)
}
}
But I'm sure there must be a more elegant or idiomatic way to do this in Gradle. I don't control the creation of the jmh configuration: it's created by a plugin. What's the best way to achieve this?

If it's fine to not really copy dependencies, but to refer to them, you could do:
dependencies {
jmh configurations.compile
}

Gradle: Use a sibling subproject as plugin

I have a project with two subprobjects: gradle-plugin and plugin-consumer. I want to apply the plugin from gradle-plugin to plugin-consumer. I tried to do this:
// plugin-consumer/build.gradle
buildscript {
dependencies {
classpath project(':gradle-plugin')
}
}
apply plugin: 'my.plugin.id'
But I was greeted with the following error:
A problem occurred configuring project ':plugin-consumer'.
> Cannot use project dependencies in a script classpath definition.
I assume this is not supported because it'd require fully building gradle-plugin before plugin-consumer can be configured.
Fortunately I can use a fileTree dependency to accomplish my goal:
// plugin-consumer/build.gradle
buildscript {
dependencies {
classpath fileTree(includes: ['*.jar'], dir: '../gradle-plugin/build/libs')
}
}
apply plugin: 'my.plugin.id'
This works, but it feels like a massive hack and leads to "bootstrapping problems".
For example, I can't clean gradle-plugin because the (deleted) jar file is necessary for configuring plugin-consumer, which must be done to (re)build gradle-plugin.
Fortunately this can be avoided by always running build immediately after clean (in the same 'run' so to speak). This can be done manually (gradle clean build) or automatically (with clean.finalizedBy(build)). Again, this works, but feels like a hack.
At last, my actual question: is there a better way to do this?
Please note that gradle-plugin is an independent plugin that's not only used by plugin-consumer, therefore buildSrc is unfortunately not an appropriate solution here.
You can publish the plugin to your local Maven repository with the Maven Publish plugin. Then simply consume it like any other artifact.
Assuming you have something similar in your plugin project:
plugins {
`maven-publish`
`java-gradle-plugin`
}
Simply publish it locally:
./gradlew :my-plugin-project:publishToMavenLocal
Then in your consuming project, something like:
buildscript {
repositories {
mavenLocal()
}
dependencies {
"classpath"("com.example:my-plugin-gav:1.0.0-SNAPSHOT")
}
}
// apply plugin

How to get Intellij to recognize properties in application.yml

I am trying to get Intellij to recognize my properties using gradle. I have followed the steps here. So this means I have a #ConfigurationProperties annotated class with some properties.
I added the spring dependency to process them:
dependencies {
optional "org.springframework.boot:spring-boot-configuration-processor"
}
compileJava.dependsOn(processResources)
I added the plugin (I've tried not using the plugin and just making it a compile dependency, no change)
buildscript {
repositories {
maven { url 'http://repo.spring.io/plugins-release' }
}
dependencies { classpath 'io.spring.gradle:propdeps-plugin:0.0.9.RELEASE' }
}
apply plugin: 'propdeps'
apply plugin: 'propdeps-maven'
apply plugin: 'propdeps-idea'
When I run the build, I see a build/classes/java/main/META-INF/spring-configuration-metadata.json file is created based off of my properties.
When I try to use the property in either application.yml or application.properties, Intellij says it cannot resolve it.
The docs does say it should be called additional-spring-configuration-metadata.json and may expect it to be called that to process it, but I do not see a way to make the build name it that way nor configure Intellij to expect otherwise.
Has anyone got this working with gradle? Or is this a bug.
Edit I created a repo with a pair of projects to demonstrate this. One for gradle and one for maven. I created the projects from start.spring.io and basically just added the properties configuration. I also used a straight compile dependency in both cases instead of optional / compileOnly.
I had not confirmed this before, but the code assist does work for maven, but not gradle. Both create a spring-configuration-metadata.json in the META-INF in their respective build folders. I am not exactly sure who is not picking it up.
Misc relevant versions
Intellij: 2017.3.4
Springboot: 1.5.9
Gradle: 4.4.1
Java: 8.161
Turn the annotation processing on
Do not delegate IDE build/run actions to Gradle
Rebuild your project in IDE: Build -> Rebuild Project
As far as I can tell, IntelliJ (at the time of this writing, 2018.1.2) wants the spring-configuration-metadata.json file to either be in a main source root (src/main/resources/META-INF/ or src/main/java/META-INF/) or in its default output directory for it to pick it up for autocompletion of properties in your source tree. To expand on phospodka's comment, you can add something like this to your build.gradle to satisfy IntelliJ.
task copyConfigurationMetadata(type: Copy) {
from(compileJava) {
include 'META-INF/spring-configuration-metadata.json'
}
into "out/production/classes"
}
compileJava {
dependsOn processResources
finalizedBy copyConfigurationMetadata
}
This answer is a combination of the (at this time) other two answers with a minor twist. In my case this is what "fixed" the issue: (in 2019.03.01-Ultimate)
Turn on the default annotation processing (File>Settings>Build, Execution, Deployment>Annotation Processors>Enable Annotation processing
Select Obtain processors from project classpath
Select Store generated sources relative to module output directory
keep other defaults
click OK
Add the code in #thyme's answer to your build.gradle
EXCEPT instead of into "out/production/classes"
use: into "build/generated/sources/annotationProcessor"
Now you should be able to run gradle clean/build and Intellij should be able to find your "additional metadata" definitions.
Notice that even though the build.gradle code doesn't explicitly mention 'additional-spring-configuration-metadata.json', it is exactly that "additional metadata" that ends up in the annotationProcessor folder as "spring-configuration-metatdata.json" where Intellij finds it.
EDIT: Also note, you need to clean / rebuild after adding any new "additional metadata" items before Intellij will see the new entries (in the freshly regenerated file).

What types (configurations) of dependencies are available out of the box in Gradle?

I want to write a Gradle script to download a JAR file from Maven and combine it with some other resources to create an RPM file using the nebula.ospackage plugin.
I can't declare the dependency using the compile configuration as it is not available without using the java plugin (and it also doesn't make sense to use compile as I am not compiling anything).
Is there a type of dependency I can use for this purpose?
Or am I required to use the java plugin?
As far as I understood java plugin will not be required. Please have a look a the script below - you can define custom configuration and use it in build script. As you can see, java plugin is not applied:
repositories {
mavenCentral()
}
configurations {
lol
}
dependencies {
lol 'junit:junit:4.12'
}
task cp(type: Copy) {
from configurations.lol
into ('lol')
}

I need debugging tips for a broken project dependency

It's configured the same here as it is everywhere else. In fact I use an import for configuring integration tests. I've done everything I can think of including a rename of local integration test tasks and configurations, including looking at the dependency tree, including running with --debug. Yet for some reason Gradle insists that the property integrationTest doesn't exist on the sourceSet for an inter-project dependency:
integrationTestCompile project(':components:things-components:abc-stuff').sourceSets.integrationTest.output
...now I'm not particularly fond of this syntax and I've already griped up a storm about inter-project test dependencies and how they should be in a test utility component. However, I'm doing it this way because this appears to be what IntelliJ will accept. Writing like this causes trouble:
integrationTestCompile project(path: ':components:things-components:abc-stuff', configuration: 'integrationTest')
How can I figure this out? I just don't get why only one project has this issue.
For the record, I've also tried:
integrationTestCompile project(path: ':components:things-components:abc-stuff', configuration: 'integrationTestCompile')
The issue is that Gradle hasn't been told to make a jar for you that you can consume in your other project.
integrationTestCompile project(':components:things-components:abc-stuff').sourceSets.integrationTest.output
Gets the classFiles and the dependencies, thats why its working using that notation. If you want to use the configuration notation you will need to tell gradle to publish a jar on the integrationTest. The jar doesn't have to be published to a repository, but will be used for the internal builds.
You can do this by doing:
configurations {
integrationTest
}
task integrationTestJar (type: Jar) {
baseName = "${project.name}-integ-test"
from sourceSets.integrationTest.output
}
artifacts {
integrationTest integrationTestJar
}
If you end up doing this in a log of projects, I would recommend writing a quick plugin that does this for you.

Why does Gradle jar of jars result in duplicate libraries?

Objective: Create Jar of Jars like Maven does.
I have this relevant snippet:
jar {
into('lib') {
from configurations.compile, configurations.runtime
}
}
There must be something wrong with my conceptualization of what compile / runtime are. If I do this, I get duplicate copies of every library in the resulting jar. I'm really only trying to include everything that might go in and cover all the scopes. I want something I can easily rubber stamp for most jar situations as this is a very large build. I can get more specific for war files.
So... Why does this happen?
The gradle documentation says this about the runtime configuration:
"runtime: The dependencies required by the production classes at runtime. By default, also includes the compile time dependencies."
Just by copying from the runtime configuration, you would get all of the compile dependencies aswell. You are basically telling gradle to copy the same dependencies twice.
