JBoss Forge new Gradle Project? - jboss

When starting a new project using JBoss Forge, the project is creating with a Maven build system by default. How do I take advantage of Forge 2.*'s Gradle AddOn to create the project using Gradle instead of Maven?
% forge
Using Forge at /usr/local/Cellar/jboss-forge/2.12.2.Final/libexec
…
[ForgePlaygroundGradle]$ new-project --name ForgePlaygroundGradle --topLevelPackage com.kedges.forgegradle --porjectFolder . **???**;

What you need here are two things:
1) After you start Forge, make sure you have installed the Gradle addon (it does not come with the core distribution):
addon-install --coordinate org.jboss.forge.addon:gradle,2.12.2.Final
2) Then you can use the --buildSystem option of the project-new command:
project-new --named ForgePlaygroundGradle --topLevelPackage com.kedges.forgegradle
Please note that the latter command may take some time to execute the first time. The reason for this is the downloading of the dependencies for a decent Java EE web project. Same happens with Maven projects when you create them with an empty local ~/.m2/repository folder.
If you don't need a web project, then consider the other project types provided by the --type option.

issue to deploy a Maven built Ext using eclipse

I created an Ext project with Maven:
mvn archetype:generate
mvn package
mvn eclipse:eclipse
mvn install
This actually builds 9 different ext "sub projects":
<project_name>-ext
<project_name>-ext-impl
<project_name>-ext-lib-global
<project_name>-ext-lib-portal
<project_name>-ext-services
<project_name>-ext-util-bridges
<project_name>-ext-util-java
<project_name>-ext-util-taglib
<project_name>-ext-web
The root project <project_name> has its own pom.xml.
Each of the 9 sub directories have their own pom.xml files and generate a JAR or a WAR file.
I imported all from the root into eclipse. This actually imports the root project and all of the 9 sub projects.
I followed the doc guide to modify portal-ext.properties:
https://www.liferay.com/fr/documentation/liferay-portal/6.2/development/-/ai/developing-an-ext-plugin-liferay-portal-6-2-dev-guide-12-en
This doc was written with an Ant build so I tried to make it using Maven but I probably missed something.
I set the updated portal-ext.properties version into:
...\<project-name>\<project-name>-ext-impl\src (into the SUB-project)
Now I wanted to deploy this and the problems starts:
Eclipse (Mars) does not allow me to drag and drop the root project (<project_name>), nor the sub-project where I added the file (<project_name>-impl).
The only one that I can drag and drop is <project_name>-ext. But if I do drag and drop this one and restart the liferay server, the ext does not work (it uses my normal portal-ext.properties and not the ext version).
Did I miss anything?
Also, am I supposed to see the portal-ext.properties in any of the jar / war files of any of the 9 sub-projects?
I do not see it in <project_name>-ext, nor in <project_name>-ext-impl
The Ext Plugin in a Maven structure is nothing you can drop into your server in the Liferay IDE - in place deployment is not supported here.
If you are a beginner - you should use the Plugin SDK (Ant).
If you really want to stick to the Maven then you will have to execute:
mvn package
in <project-name> and put the file <project-name>-ext\target\<project-name>-ext-x.x.x.war into LIFERAY_HOME/deployments and restart your Liferay server.
Disadvantage: For redeployment you will have to remove all deployed files and do the whole thing again. Up till now there is an Ant but not a Maven task for redeployment.
Finally you have dropped your portal-ext.properties at the wrong position. Maven is expecting resource files at /src/main/resources, so correct position is .../<project-name>/<project-name>-ext-impl/src/main/resources/portal-ext.properties.
And if the portal-ext.properties is the only reason for the Ext-Plugin: You can simply put that file into LIFERAY_HOME - no need for an Ext plugin here. And some properties are overridable in a Hook as well - which is easier to build and deploy, if you really want to create a package for modification here.
BTW: I'm using Maven for Ext Plugins as well - but in combination with some custom builders for hot deployment from Eclipse.

How to use eclim with gradle project

My eclim setup working perfectly with eclipse project. But I want to use gradle build system.
I am working with Libgdx framework and it provide gradle templete project.
So is there any way to use eclime + eclipse + gradle
Your best bet is to check out the Eclipse Gradle plugin, although in short you can add apply plugin: 'eclipse' to your project and then run gradle eclipse from your terminal in the root folder of your project. That should generate the necessary files for Eclipse to recognize your project, although you might need to edit the .classpath file for proper autocompletions.
That will get Eclim to recognize your project with :ProjectOpen and proper autocompletion and other goodness.
The bad is that Gradle tasks and changes to your build.gradle will require manual changes to the Eclipse side of things.
Edit: There's a new plugin available for this purpose that replaces eclim for gradle projects (but is android oriented) called Vim-Grand. It's pre-alpha and you'll want the refactor branch for now, but it's working well enough for me
You should combine it with YouCompleteMe.
What I did was use the gdx-setup.jar to create my project. I then imported it into eclipse like a normal gradle project. I closed eclipse and started up elcimd. Put "let g:EclimCompletionMethod = 'omnifunc'" in my .vimrc file. Followed the elcim instructions to use :CreateProject and that was it.
This guide was really helpful: http://www.lucianofiandesio.com/vim-configuration-for-happy-java-coding
I am able to get most or all Eclim functionality working with my libgdx project this way:
create a new libgdx project with their tools
start Eclipse
Import --> Gradle Project --> Build Model per usual libgdx project creation
shut off Eclipse, start Eclim
I get organize imports, java validation, autocompletion, all the good stuff.
That said, I want to figure out how to do this all without having to use Eclipse. I think the missing piece is the Build Models functionality. Still researching ...

Automating build tasks using eclipse / maven m2e

I am about to use maven to automate my builds. Unfortunately, I am not able to get all the features I want, even after reading several tutorials :(
I would be glad if somebody could explain a way I can achieve all my goals!
I want to automate 3 specific build tasks with several actions for a project from within eclipse, using m2e:
Build snapshot
compile
define current project version + date as version
build jar file
copy jar file into the local repository in the project path itself (§{project}/builds/)
Debug snapshot
build snapshot as mentioned above
copy jar file to plugins folder of a local test server
build another project the current project depends on, copy its jar file to the plugins folder aswell
launch server / connect to eclipse debugger (I know how to do that, the previous steps are the important ones)
Create release
compile
define current project version as version
build jar file
copy jar file into the local repository in the project path itself
create javadoc
copy source files and javadoc to an archive folder
increase the project version (for example v6 -> v7)
As mentioned I don't need a perfect solution, just a way to realize this ;)
(Annotation: Chaining multiple launch configurations is not a problem.)
Edit:
Which sections of the pom.xml do I have to modify to realize these steps and how can I invoke them using an eclipse launch configuration?
Hi based on your requirements i can say the following:
Build Snapshots
Building a SNAPSHOT is usually the convention during development cycle.
1.1 just using the conventions.
1.2 Date as version
This is a bad idea, cause Maven has some conventions how a version looks like (1.0-SNAPSHOT or 1.2.3-SNAPSHOT etc.)
1.3 Build jar file
Usually done by the jar life cycle (mvn package)
1.4 The local repository is on your home drive in ${HOME}/.m2/repository for all your projects. Technically you can do what you like but it's against the Maven conventions. The question is why do you need such thing?
2.1 Usual procedure
2.2 Usually a deployment is not a job for Maven but you can do such things by using cargo-maven-plugin (integration testing).
2.3 If you have dependencies between project you need CI solution like Jenkins to do such things otherwise you need to do this manually. But that is different from a multi-module build.
2.4 Integration testing different story. Depends on what exactly you like to do.
3.
1-7
The maven-release-plugin will handle such things except copying to the project path itself which is against the conventions. For such purposes you need a repository manager.
I can recommand reading these books: http://www.sonatype.com/Support/Books

gwt-maven-plugin with Eclipse Indigo

I would just like to setup a new GWT project in Eclipse and use Maven for dealing with all the jar jungle. I used gwt-maven-plugin with this instructions, but I can't get the project to work in Eclipse.
What I've actually done:
Created a maven project using the archetype gwt in command line.
Imported the projet in eclipse using import > existing maven project
While doing that I had errors saying:
gwt-maven-plugin:2.3.0-1:generateAsync - "No marketplace entries found to handle"
gwt-maven-plugin:2.3.0-1:i18n - "No marketplace entries found to handle"
gwt-maven-plugin:2.3.0-1:exploded - "No marketplace entries found to handle"
These errors don't go away even if I ignore them on the import.
How can I make these projects working? Is the problem that I skipped the "process-resources" setting? (There is no such setting in the latest version of m2e.)
Should I even use gwt-maven-plugin? Is there any other way of making a GWT project to use Maven? Or – is there any other way to fight with the jar jungle? What does GWT guys use?
I use Eclipse Indigo with m2e plugin 1.0.0 and Google suite plugin version 2.3.3.
Eventually I gave up Maven. As one other developer said "good ideas and bad code build communities faster" , I also remember my experience with Maven on all the projects: very promising on the beginning, but eventually you get to some problems and end up working more with configuring Maven than actually dealing with your own code.
I decided to manually copy needed .jar-s into /lib folder. I spent some time due to transitive dependencies, but LESS than dealing with Maven and now I have things under control. If sometime in the future working with libraries will become an overhead, I will consider using Ivy.
If someone wishes to stick with Maven, I lately found a very useful link by Google team:
http://code.google.com/p/google-web-toolkit/wiki/WorkingWithMaven
They recommend using their sample projects and not gwt-maven-plugin archetypes (due to issues). I agree. They also provide needed pom lifecycle changes for Eclipse Indigo.
According to a recent post on the gwt-maven-plugin mailing list the Maven integration is not complete for Eclipse Indigo, since the M2Eclipse 1.0 release has brought about a large number of changes. The suggested workarounds from David Chandler, Google engineer, are:
You can run "mvn package" on the command line or right-click on the project > Maven > Run as > Maven build.
The plugin execution failures you're seeing can be resolved by adding lifecycle mapping metadata as in the sample POMs. They are only needed for Indigo. You should not get these errors in Helios or when running mvn package from the command line.
Disclaimer: The following guidelines are for Windows users. These steps are on the basis that, they have worked when tried by the replier and doesn't guarantee fulfledge working unless experimented by self and tried with proper prerequisites.
::Creating a simple gwt project using archetype::
Following are few commands that can be used to create a simple gwt project "Web Starter Application":
mvn archetype:generate -DarchetypeGroupId=org.codehaus.mojo
-DarchetypeArtifactId=gwt-maven-plugin -DarchetypeVersion=2.3.0
mvn -DarchetypeGroupId=org.codehaus.mojo
-DarchetypeArtifactId=gwt-maven-plugin -DarchetypeVersion=2.3.0 -DgroupId={project packaging} -DartifactId={application name} -Dversion=1.0 org.apache.maven.plugins:maven-archetype-plugin:generate
mvn -DarchetypeGroupId=org.codehaus.mojo
-DarchetypeArtifactId=gwt-maven-plugin -DarchetypeVersion=2.3.0 -DgroupId={project packaging} -DartifactId={application name} -Dversion=1.0 -Dmodule={module name} org.apache.maven.plugins:maven-archetype-plugin:generate
(The value of archetypeVersion can be 2.3.0 or any higher stable version.)
Few coordinates are required by maven to create the gwt project. They are as follows:
groupId
artifactId
version
module
The first command doesn't take any of the above coordinates hence, we need to supply them at the time it executes. Notice that the archetype goal is mentioned right at the beginning of the command. It is mandatory to give the archetype goal.
The meanings of these coordinates can be found here.
One of the best ways to start with understanding maven is this.
The second command doesn't consider the module name hence, you will be prompted to give it at the time the command executes.
The third command is equivalent to running it in batch mode where you just have to confirm the inputs for groupId, artifactId, version, module as mentioned in command itself.
Once any of these commands gives a BUILD SUCCESS result, then navigate to the just-now-created project folder from command line and execute the following command:
mvn gwt:run
It should start the project in Development Mode so that you can Launch the Default Browser to run the project or Copy the URL to clipboard and navigate to it through any browser.
Good luck with the execution.

Grails Project - Common Java Project Dependency in Eclipse

All,
We have standard java projects that contain our common data model, common util classes, etc...
What I can’t seem to figure out is how, to make my Grails project (in Eclipse) have a dependency on the other standard (non Grails) java project in the workspace. When I add the project in the “Java Build Path” the project doesn’t show any compiler errors, but it when I run “Grails Tools -> Refresh Dependencies” or attempt to run the project (run-app) it fails.
This seems like it would be a pretty common thing, but I have searched all over the web and have been unable to find a solution. We are not using maven in our environment. Since we build Eclipse RCP applications on the client side, we use OSGI manifests to manage our project / bundle dependencies.
You can use linked source directories to include the Java or Groovy dependencies in the grails project and you need to set the output directory to Project/target/classes (these configurations go into the grails project preferences in Java Build Path options -> Source Tab).
The change in the output directory allows Eclipse to detect changes in the dependencies and auto load it when running the app using grails run-app.
You can use autocomplete and debug the sources of the dependencies with this configuration.
I prepared a step and step process that includes screenshots for Java and Groovy here
The documentation includes information on customizing the build.
You can add this to your BuildConfig.groovy:
grails.compiler.dependencies = {
fileset (dir:"/path/to/jars")
}
That should get you started.
If the dependencies are not stored in an Ivy/Maven repository then AFAIK your only option is to copy the dependencies to the lib directory of the Grails project.
