I am kind of new to PlayFramework 2 and can not figure out how to resolve play 2 application dependencies. I need to add dependency on a local module loaded in IntellijIdea, not a jar file or repository.
While adding module dependencies in Idea project setting works just fine and ide itself is able to resolve them (autocompletion, imports etc are working), when trying to run in play2, its compiler cannot resolve any dependencies.
I manually configured Build.scala (adding val appDependencies = Seq("" % "" % "")) but am puzzled as to what resolvers I should use. I cannot point to a jar file, as it is a work in progress and such a file should be updated too often. Doing so would defeat the whole purpose of managed dependencies.
Play's main build mechanism uses SBT, which needs to know how to find all sources required for the build. There are several options for this:
make your module an SBT project itself and publish it to your local ivy repository. However that might be somewhat complex at this stage, and would involve adding your local ivy repository to the resolvers and re-publishing every time you change something in the module
declare your module as a sub-project. Play's documentation describes the process of working with sub-projects, I think this is the way you'd like to try out since then the idea command on Play's console will generate the IntelliJ configuration for the main application and the module.

Presently having an annoying time getting a jar added to the external library for the project, then in turn not disappear when syncing and the imports working. Adding I figured out and answered in another question. The issue is to keep persistent and accessible to a jar I create within the project for import.
I am not sure if I am missing a step or forgot to set something. I am using a modified gradle (forgegradle) to create the project. Have not found a solution with the documentation, or any for IntelliJ yet. I am generally new with IntelliJ, choosing to use it instead eclipse which I have previously used.
The goal is a to create an add-on for a mod to another jar. The main jar already in the external library from the start, now attempting to add the mod to it. I could modify the mod, but it is not my code, so rather not simply modify it directly and repackage it.

If you are using an external build tool / system that syncs with IntelliJ it is recommended to use that build tool / system to add dependencies.
IntelliJ will always take a backseat, and treat the build tooling / system as the source of truth for the project model as best it can.
You mention you are using gradle, I would recommend adding the dependency as a managed dependency that is, let gradle download it from a repository, and resolve the dependency/library itself.
If you can not do this, and you can't host a repository yourself, The next best recommendation I have, is creating a 'libs' folder inside the project, that contains jars that can't be found in repositories (They may be mods or plugins that were never published)
You can read up on how to add a library folder to gradle here: How to add local .jar file dependency to build.gradle file?
We have a java project with several modules. We use git for versioning and want the developers to be able to chose their own IDE. So we don't push .idea and .iml files with git. This means that developers in IntelliJ needs who clones from git needs to set up the project in IntelliJ as well. However we are having some issues with setting it up. In my own project it works fine and looks like:
Proejct Module (Is this a real module?)
⤷ Module A
⤷ src
⤷ main
⤷ java
⤷ Package 1
⤷ Package 2
⤷ test
⤷ Module B
Before we added packages to the project new developers could just pull from git and open Module P in IntelliJ, then go to project structure and import module from Module A and Module B. However if they try the same thing now IntelliJ tries to make the Modules main and test from Module A.
A workaround we temporarily use for this is to open Module A and B directly as separate IntelliJ projects. If we do this IntelliJ does not try to make modules out of main and test. However this is very inconveniant for us.
How can we fix this?
It's a good approach to make your source control system "agnostic" about the IDE and not check in .idea, *.iml and equivalent things from other IDE's.
However you really need to use a build control system like maven or gradle.
In my workplace we use maven for all our java projects. It's very simple to define a pom.xml at the root level which defines your modules, and many other things.
When you import a maven project into intellij, all the relevant IntelliJ modules are automatically created for you. In essence, you only need to import the pom.xml and you're good to go.
Otherwise it will be a nightmare to import and create modules every time you check out source from git. Maven isn't perfect but I highly recommend using either maven or gradle.
To define multi-modules from the root pom.xml, make a section like this:
<modules>
<module>module-A</module>
<module>module-B</module>
</modules>
And then the pom.xml in both module A and B should define a section referring to the root pom via the <parent> tag.
We are trying to setup a number of Gradle (v1.5) web projects in IntelliJ v12.1.2
The new JetGradle integration works fine until we get the the Artifacts
The module is imported as a Gradle project, the artifact is been created as a Web Application (Exploded) and the Web facet has been added - all the dependencies that are declared in the build.gradle file are correctly added to the WEB-INF/lib directory in the artifact
The problem comes when we make a change to the dependencies in the build.gradle file and refresh the module using the JetGradle refresh button - the dependencies of the module are updated correctly but nothing is changed in the artifact
If we changing just one dependency then the change can be done manually but if there are a number of changes or there are a lot of new/changed transative dependencies then it seems the only timely way to get the correct dependencies in the artifact is to delete and recreate it
Am I missing something obvious, does anyone know a better way to update the artifacts
Thanks
Automatic artifact config update is not implemented yet. I've created corresponding ticket for that - http://youtrack.jetbrains.com/issue/IDEA-109369
Here is my situation. I have a play app which uses the guice module. In order to work with the guice module:
I installed it using play install guice. This installs it in the $PLAY_HOME/modules which is fine by me. I don't want to edit the module files in any way whatsoever.
Then I declared the module in my dependencies.yml like so: - play -> guice 1.2
Within my app, I ran play dependencies, and this resoles the module just fine and creates a modules/guice-1.2 file that references the guice module.
The issue is that the content of that file is something like the following: /some-absolute-path/play-1.2.x/modules/guice-1.2.
That works fine when working locally for development. But when I want to move to a production server, with a different install of Play! (i.e. with a different absolute path to it) it will obviously fail.
So what's the best way to deal with this?
For now I've resorted to declaring the module in the application.conf file like this: module.guice=${play.path}/modules/guice-1.2.
Unfortunately the ${play.path} magic doesn't seem to work on those generated files.
By the way I use version 1.2.3 of Play!
you should try with ${application.path} in your dependencies.yml file, like in this example
require:
- play -> crud
- provided -> DateHelper 1.0
repositories:
- provided:
type: local
artifact: "${application.path}/jar/[module]-[revision].jar"
contains:
- provided -> *
see this question: How can I specify a local jar file as a dependency in Play! Framework 1.x
When you run in production you will either resync the dependencies (via play deps command) with the local installation of Play or in some scenarios you can precompile everything and then there will be no issues with the paths.
That second scenario is the one with Heroku, for example.
It's not answer to your question, but I have faced with same issue.
I don't want to call resync the dependencies on production.
I don't want to ask my team members, install special module.
I don't want to commit file containing absolute path with module location.
The only workaround that I find: do not install module in Play! application, just include jars which use this module manually. play-guice.jar should be included as #opensas suggested, aopalliance and com.google.inject as regular dependencies in dependencies.yml.
The funny thing, that resync dependencies is also deleting .svn files, so back-up its before calling this command.
After a lot of good comment about IDEA, I decided to give it a try. I downloaded the Community Edition and would like to use it for PlayFramework development.
I have followed official documentation and some other information gathered around, but I have not succeeded completely. When using a project with differents (play) modules, the different classes are not found.
For example when using Secure module, IDEA keeps complaining about not finding Secure.class. It has to be a classpath issue. I tried to attach Java source & classes ($PLAY/modules/secure/) in module settings (F4), class is still not found. Did I miss something?
BTW, I have done a play dependencies and play idealize, which seems to add another module Secure into project in IDEA.
Thanks,
The answer is to run the following:
play deps
play idealize
This forces the IDEA .iml project file to be refreshed with the updated class path entries for the new module (in this case Secure).
A issue I came across using IntelliJ and Playframework.
The log4j.properties file or log4j.xml file are not in classpath by default. You have to add the conf as a source folder in module settings.
You need to add the Secure module you have created in IDEA as a dependency to the main application module:
Go to File -> Project Structure
Choose the main module
Choose the Dependencies tab
Click Add -> Module Dependency
Choose the IDEA Module you created for the Play Secure module
Also make sure you have the correct source path selected for the Secure module in IDEA.
