Using Gradle to Build an IntelliJ Module From Command Line - intellij-idea

I understand the basic functionality of gradle, but I don't understand how to use a build.gradle file other than the one in the project's root. I have a project which contains a gradle wrapper in it's root, and a module which has it's own build.gradle file. How do I specify for gradlew to use the module's build.gradle file instead of the one in the root directory?
Specifically, I have an IntelliJ project I have uploaded to my CI server, and I am trying to setup a script to run the builds automatically.
Cheers

It looks like you have a multi-module build which only has a single module... correct?
You could include a settings.gradle which points to the module
You could declare a GradleBuild task in the root module to invoke the sub module.
A good place to look for inspiration is the java samples and the organizing build logic page in the documentation. An impressive feature of gradle is that all of the code snippets which appear in the documentation is sourced from the samples directory which is run as part of their CI build.
Happy Gradling!

Dependency on package in git without jar file

I am distributing a Java package via git for other people to use. I am currently supplying a jar file to go with the source. This way, the user only needs to clone the project once into Intellij IDEA. Projects using the package can then follow this procedure
Correct way to add external jars (lib/*.jar) to an IntelliJ IDEA project
to use the package.
This works, but distributing a jar does not feel nice security-wise. On the other hand, this discussion
IntelliJ IDEA - adding .java file to project dependencies
suggests that to use the source code, you need to copy it into your src folder.
Is there a way to distribute source code (java files) only so that if multiple projects use the same package
the package only needs to be downloaded once
the package can be kept up to date with git pull?
I would really recommend not include jar or any binaries in a Git repo and the best approach to keep these dependencies in a local Nexus repository and use maven or Gradle as your dependency management tool.
I found a working solution:
Supply an Ant build file with the package. The build file compiles classes and packages them into a jar file. The default target is building the jar, which depends on compiling the classes.
Provide users with instructions on how to set the given Ant build file as a build file in Intellij IDEA and build the default target.
Then instruct them to follow the steps in the first link above to add the jar as a dependency.

Gradle dist folder on IntelliJ classpath

We have a project which we build with gradle. We use IntelliJ as our development environment.
We have some resources we want to keep outside the JAR and so we have put them in the src/dist-folder. This works fine when running the application from the command line, but not so good when we want to debug from IntelliJ.
We could put a runtime-dependency to src/dist, but then we end up with files inside our lib-folder in the generated ZIP file and that's not what we would like to have.
Bottom line: how can we keep some resources outside the JAR (in src/dist) and also on the classpath of IntelliJ (as generated by Gradle; I don't want to have to add things manually to the IntelliJ classpath). The directory structure in the resulting zip should be something like:
root
|
|- config/*
|- css/*
|- lib/*
It seems that this question describes a similar problem, but the solution in addition #4 still mentions that no solution was found to correctly get the resources on the classpath of IntelliJ:
Gradle build file with conf folder with properties not in jar but on classpath
The solution I've used in a similar situation is to:
Use the Idea plugin in gradle rather than relying on the IntelliJ support.
Once that is working you can tweak the source path that IntelliJ uses in the gradle file itself

How to get IntelliJ to associate Gradle sources with build.gradle?

When writing Gradle scripts for my Java project, specifically, when writing build.gradle files, IntelliJ does not recognize the Gradle API.
For instance, Gradle methods calls like apply, dependencies configure appear with a black line under them and it is not possible to navigate to method declarations, there is no auto-completion etc.
I managed to work around this by adding compile gradleApi() to the build's dependencies block. However, I don't want to have this explicit dependency in my code.
I tried editing IntelliJ's project structure and add a dependency on a Gradle library (tried gradle-core and gradle-all) to my modules, but that seems to have no effect.
Is there a way to make IntelliJ associate all build.gradle files with the Gadle sources?
I solved this problem as follows:
As mention in already posted answers, configure gradle
update gradle/wrapper/gradle-wrapper.properties file
change bin to all in distributionUrl i.e.
distributionUrl=https\://services.gradle.org/distributions/gradle-6.8.3-bin.zip
to
distributionUrl=https\://services.gradle.org/distributions/gradle-6.8.3-all.zip
OR
[optional] If you are using old version of gradle wrapper and wanted to upgrade, then execute
./gradlew wrapper --gradle-version 6.8.3 --distribution-type all
Update gradle task (if present in build file)
wrapper {
gradleVersion = '6.8.3'
distributionType = Wrapper.DistributionType.ALL
}
Before importing the project to IntelliJ-Idea IDE, update build.gradle and add java and idea plugin to the plugins list
plugins {
id "java-library"
id "idea"
}
From a terminal, execute ./gradlew clean build idea or simply ./gradlew idea
Import project to IntelliJ idea.
Go to Preferences --> build,Execution,Deployment --> BuildTools --> Gradle
You can see
Restart IntelliJ idea IDE.
So above we have configured both of the options so choose either of them, except the specified location option. That's it.
Before
After
Autocomplete functionality as mentioned in this answer.
I had similar frustrations with Grails 3, which defines and runs a wrapper task when an app is created. Changing to the "all" zip in the wrapper properties file did not work because this kept getting changed back to the "bin" zip.
This was solved when it was understood that the "gradle-wrapper.properties" file simply stores the values from the "wrapper" task, and if this task is run after the properties are changed, they get changed right back.
This is easily fixed by setting some properties on the wrapper task:
wrapper.gradleVersion='3.2.1'
wrapper.distributionType=Wrapper.DistributionType.ALL
Now importing the project into IDEA gives you smart editing of your build.gradle.
when I choose build.gradle in IDEA and open it, IDE prompts
You can configure Gradle wrapper to use distribution with sources. It will provide IDE with Gradle API/DSL documentation.
I choose Ok, apply suggestion!
after project refreshing I am able to use code completion
before you import your project, configure it to use the customizable gradle wrapper as per the instructions here :-
https://docs.gradle.org/current/userguide/gradle_wrapper.html
add a task to your top level project like this:-
task wrapper(type: Wrapper) {
println "Wrapper gradleVersion = '2.12'"
gradleVersion = '2.12'
}
or whatever the latest version is.
make sure you can build the project from the gradle command line before you try importing into intelliJ, using the ./gradlew command, which will download and install a gradle distribution for you the first time you build.
set your java home, intelliJ home and gradle home variables in your machine and in intelliJ (mine look like this, yours may be different depending on your setup and your history of hacking around your machine...:-
(from .bashrc
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home
)
When you do import, choose the customisable gradle wrapper. if all is well, when you open the top level build.gradle for your project, you will be asked to configure sources for the gradle dsl, which will also update your gradle wrapper properties file to this:-
#Thu Mar 31 14:04:00 BST 2016
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-2.12-all.zip
.. the change being from ... bin.zip to all.zip. and that's it. This had been giving me lots of grief for a long time, but that's the way to do it. (on IntelliJ IDEA 2016.1 CE at least...)
most of this was in
Dimitry's answer too, but I couldn't get it to work using the default wrapper , it had to be the customisable wrapper.

Configure IDEA to deploy using ivy

I have a project that uses IVY. My build script resolves the dependencies well.
I have a library (lets call it Project_libs) configured in IntelliJ iml file so that when I deploy the application the jars get published to the server.
I have an ant task ide-setup which copies the necessary jars from Ivy local repo to Project_libs so these jars are available to IDEA during deployement.
Lets say I make changes to a common library like utils.
Build the common library.
Go to the projects that declared this common library as a dependency and run ide-setup
Then start the server.
Is there a direct way in which I can configure IDEA to read the dependencies from the ivy.xml file instead of doing this convoluted process of setting up the whole thing.
I don't know anything about InelliJ IDEA, but I believe you could accomplish what you want using ant and IVY. From the IVY documentation
<ivy:buildlist reference="build-path" ivyfilepath="ivy/ivy.xml" leaf="mymodule">
<fileset dir="projects" includes="**/build.xml"/>
</ivy:buildlist>
Builds a list of build.xml files sorted according to the ivy.xml files found in an
ivy directory relative to those build files. Only build.xml files of modules which
have dependencies (direct or transitive) on mymodule are put in the result list.
So if you set leaf equal to utils, it could return you a list of build.xml files that depend on utils in dependency order. Then all you would have to do is go through those build.xml files in order and invode their build process (probably through a subant call)

logback.xml and running application from JetBrains IDEA IDE

When I develop application in IDEA, where should I place logback.xml for it to have an effect on the application?
It seems when you run/debug IDEA doesn't make any jars and doesn't invoke Maven to build something. Does it execute main() directly from compiled *.class file? If so, where can I put logback.xml so that it would have effect?
logback.xml should be available in the root directory of your CLASSPATH. When you run your application, the full CLASSPATH is printed at the very beginning. When I put logback.xml in /src/main/resources (Maven project) it works without any problem. Also putting it in /src/test/resources with logback-test.xml name has presence.
Simply run:
getClass().getClassLoader().getResource("/logback.xml");
And see whether it returns something or null.
If you are not working with Maven project, open Project structure (Ctrl + Alt + Shift + S) and add in Modules section select folder containing logback.xml and mark it as Sources (blue icon).
For me: I simply needed to re-build the project (not just re-run or re-compile the project). Changing the src\main\resources\logback.xml did not affect logback because the class loader is picking up the logback.xml that is in the target/ folder, not the /src folder. This makes sense since target is the run environment. Therefore, a build is required to transfer the new xml file over to target.
