Netbeans has an option to build all dependencies. I read it uses maven reactor plugin to achieve this. How does it achieve that.
Can it be achieved using maven through command-line.

There appears to be an Eclipse plugin for Gradle, but no Gradle plugin for Eclipse...
Simply, I'd like to add a build.gradle to my Eclipse project, write its contents (including defining its dependencies), and then run it from inside Eclipse, the same way I can run Ant scripts from inside Eclipse.
When it runs, I'd expect the plugin to pull down all dependencies and make them available to my project's classpath in Eclipse.
If no such plugin exists, then I ask: what's the best way to develop in Eclipse, but keep your builds managed by Gradle? If I decide I need a new xyz.jar as a dependency for my code, how do I add it as a dependency in such a way that both Gradle and Eclipse will recognize it (and not throw compiler errors)?
Either use the IDE project generation approach (gradle eclipse), or use the Eclipse Gradle Integration. In both cases, you'll want to apply plugin: "eclipse".
The Gradle plugin for Eclipse is part of the Spring IDE. It understands the dependencies specified in the build script and makes those available in the .classpath.
I made simple maven project and I opened it with Eclipse. I have installed maven plugin for Eclipse. I'm interested in following:
How Eclipse compiles code when I hit save on my source code (does it use configuration from ant or maven or something else)?
When I run tests from JUnit plugin for Eclipse those Eclipse calls mvn test (I suppose not, but what is then happening exactly)?
Is it possible that maven does the build successfully but Eclipse is
showing errors in code?
The Maven Integration for Eclipse makes it easier to edit POM files, allows you to execute maven builds from within Eclipse and to help with dependency management. It doesn't actually compile your code (unless of course you execute a maven build from within Eclipse). The main help is with the dependency management and writing the .classpath file of your project within Eclipse.
To try and answer your questions:
Eclipse uses its standard mechanism to compile code. With a standard eclipse for java developers your project will have a Java Project nature and Eclipse will then use the Java Development Tools - JDT to compile the code. (Internally this uses an incremental builder to build the code http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Fguide%2FresAdv_builders.htm). What source files it will compile and where it will place the resultant .class files is configured in your project's Java Build Path (which I am guessing the maven plugin may well configure for you)
JUnit support is part of the Java Development Tools as well.
It is possible that maven will successfully build a project outside of Eclipse, but that the same project will show errors within Eclipse. This is usually down to classpath errors (dependencies defined in the project's POM not being added to the classpath in Eclipse). If you are using the maven plugin with eclipse this probably shouldn't happen. If you are not using the maven plugin within eclipse you can execute maven eclipse:eclipse to have maven update the Eclipse .classpath file of the project which should then fix any of these problems.
I have a project that depends on a library that is only easily available through Maven (OpenIMAJ). I have set up a Maven 3 project in NetBeans 7, and can develop my code that way. I would like to integrate the build product from this Maven project into a larger NetBeans project that does not use Maven 3. What's the smoothest way to get the JAR output from the Maven build process into my Netbeans (non-Maven) project, with the proper dependencies in the classpath?
Build & install Maven-project to local Maven repository (Or deploy to shared repository)
In non-Maven-project, express a dependency on the JAR (?) built by Maven-project just like you would for any other JAR
In Eclipse it is possible to configure builders for a project. I am using m2e and Eclipse indigo for a dynamic web project. I am trying to figure out exactly what happens when I invoke Build for the project from eclipse and so be able to understand the difference between this and a just doing a maven build from the command line. I go to project / builders and see there are five builders: JavaScript Validator, Java Builder, Faceted Project Validation Builder, Maven Prokect Builer and Validation. It would be interesting to see what goals the Maven Project Builder will do but I can't see this from this screen. Edit is disabled. I try Project Properties / Maven and there is nothing to do with Goals there. Even though this http://maven.40175.n5.nabble.com/Preventing-Maven-project-builder-from-being-run-td137622.html suggests there should be.
I am wondering is there any way to see and configure what goals Eclipse will call?
Many thanks.
Strange as it sounds, m2e does not really invoke Maven to do the build.
Its job is to parse POM file and delegate the job of doing everything that it finds there to Eclipse.
It does so by mapping maven plugins to special m2e Eclipse plugins.
Sometimes, when no mapping exists you get a warning and you have a choice of either disabling this part of your build or running the maven plugin in I guess default wrapper provided by m2e. In either case the result is not as good as when a maven-to-eclipse plugin mapping exists
I'm using Netbean RCP to develop my desktop application.
my goal is to use the "cruise control" for overnight builds.
I just can't find any information of how to build all Java sources to compounded jar (consisting of all netbeans modules).
I want also to be able to define that if ,for instance,case the org.openide jar is missing, it will d/l it as need.
I have 2 questions:
can i run the IDE automatic build outside of netbeans IDE?
how can i define the internal\external dependencies for my project.
Netbeans use an ant file for conducting the 'background' builds, if you haven't specified a build file yourself.
You can use ivy if you wish to stick with ant or you can use maven, which was designed for exactly this task
