I'm currently trying to create a basic Java project. The first option that appears is "Java with Maven", which I already used, but isn't giving me the "Create Main Class" option that I need.
I'm using Apache Netbeans IDE 11.0, running on Windows 10, x64.
I've given it a whole day, updating and installing the most recent JDK versions I found, and still I'm unable to make it work.
I've also read this answer, but it's not working:
Can't create project on Netbeans 8.2
Here's an image of what I'm getting:
Any help is appreciated, thanks.
The project templates were revised in Apache NetBeans 11.0 to give Maven projects greater prominence. From an Apache NetBeans blog post:
Restructuring of Project Templates in Apache NetBeans
There's been lots of discussion in the Apache NetBeans community about
how best to express the fact that Apache Maven and Apache Gradle are
more modern choices to be aware of than Apache Ant, while at the same
time not implying that there's anything wrong with using Apache Ant.
Here's what we seem to have reached consensus around, i.e., move all
Ant-based project templates into a separate Ant-specific folder, while
putting the other two build systems higher and therefore more
prominently in the list:
With the above, someone is less likely to simply go to the
no-longer-existing Java category and then end up with an Ant-based
project, without thinking about it. By default, the user of Apache
NetBeans is now encouraged to consider Apache Maven and Apache Gradle
first. The old Ant-related categories are still there, so as not to
confuse anyone completely, just structured within a lower ranked "Java
with Ant" category. The above also solves the discussion re "Java EE",
i.e., here the idea, from discussions, is to name the category "Java
Enterprise".
At startup, all categories are closed, i.e., none is more prominent
initially than any other.
An objection one could have is that, if you're a complete Java newbie,
you won't know what Maven, Gradle, or Ant are. Well, that has always
been the case and NetBeans has artificially hidden that choice by
having a category simply named "Java", which then resulted in everyone
ending up with Ant-based projects. To turn that around and have a
category simply named "Java" that results in Maven-based projects is
probably not right either, i.e., a careful balance needs to be struck.
So if you created a project using File > New Project... > Java > Java Application in earlier releases of NetBeans, you should use File > New Project... > Java with Ant > Java Application in NetBeans 11.0.
Notes:
NetBeans Bug Report NETBEANS-2040 Maven First in New Project Wizard refers.
Also see the discussion at the start of this YouTube video The Rough Guide to Apache NetBeans 11.0.
Other project wizard changes in NetBeans 11.0:
In NetBeans 11.0 I had to install the Gradle plugin (Tools > Plugins > Available Plugins > Gradle) in order to see Java with Gradle in the Project Wizard.
In earlier releases of NetBeans you created a Java Enterprise project using File > New Project... > Java EE > ..., but in NetBeans 11.0 this has changed to File > New Project... > Java with Ant > Java Enterprise > ...

I am trying to configure Grails in Netbeans.
Grails version:3.2
Netbeans: 8.2
JDK: 1.8
OS: Windows 10
I have install and configured environment path and other stuffs. I can create and run project from the Command Prompt. But I can not create project from netbeans.
Warning |
Unrecognized flag: non-interactive.
Error |
Specify an application name or use --inplace to create an application in the current directory
This error is showing, to create project from Netbeans. I can run the created project though. I have already added Groovy plugin.
How can I solve this problem?
I don't think you are doing anything incorrectly. I have an environment very similar to yours (Grails version: 3.3.2, Netbeans: 8.2, JDK: 8u151, OS: Windows 10) and I see the same error: Specify an application name or use --inplace...
This is a known issue with NetBeans 8.2 that has already been bug reported; see Bug 258407 - Error when creating a Grails 3.1.x project. The problem has been confirmed to exist in Grails releases 3.1.0 up to 3.1.4, but I see the same issue in 3.3.2, and there is no fix for NetBeans 8.2.
However, I successfully created a Groovy/Grails application using JDK 8u151 with a DEV release of NetBeans which you can download from here: http://bits.netbeans.org/download/trunk/nightly/latest/
Note the caveat that comes with using DEV releases of NetBeans:
These builds are still under development and could contain defects
that lead to data loss. They are meant for evaluation of new features.
As always, be sure to back up your changes if you use these builds on
your production code.
As long as you can you can live with that situation, using a DEV release is your (only) solution for creating Grails 3.x applications in NetBeans.
One final point: unlike NetBeans 8.2, DEV releases of NetBeans support Java 9 as well as Java 8, but don't use Java 9 when creating a Groovy/Grails applications. It won't work for a completely unrelated reason.
I'm using Windows 8 and Grails 3.3.8, but the following worked for me:
Create the project using system command line (I used instructions in this page: how to create grails project through windows command promt).
Import the project to Netbeans 8.2 by clicking on File > Open Project... and selecting the project folder.
This solution works for me (Mac OS)
1) Open de console inside Netbeans
2) Navigate to your GRAILS_HOME/bin
3) Type grails create-app [YOUR_NAME_APP] --profile=web (rest-api, etc)
4) The project must be created at GRAILS_HOME/bin/[YOUR_NAME_APP]
5) Do not try to import into Netbeans instead of it Open the project
6) Start coding!
You can move the folder GRAILS_HOME/bin/[YOUR_NAME_APP] to the Netbeans workspace before open the project.
FYI, I am using netbeans 9 and grails 3.3.8 (dont use 3.3.9, its broken), and it works like a dream. I can create domain classes etc. from the menus in netbeans, run, debug etc. THe only thing I had to do was manually install the grails plugin for netbeans, and configure my grails paths etc. The answer on how to set this up is here: how to open a grails 3.3 app in netbeans 9?
The only thing I cant get to work (and its a bit of a show stopper), is multi-module projects (i.e. a grails app which depends on a grails plugin). I can run them, but netbeans does not recognise any of the imports so there is no code completion and it shows all files are having errors. What a shame, as appart from this, netbeans has very good grails support.
Note, I always create projects on the command line, e.g. "grails create-app myapp ...", then simply use the open project menu in netbeans and it instantly recognises them as grails.
Ensure you have gradle plugin installed for netbeans. Then go to File -> Open Project.
You should see the project shown by netbeans as a gradle project.
To preface, I am a student and have limited experience with IDEs. My situation is that I currently have two versions of Eclipse on my machine (OSX El Capitan), one being a C/C++ IDE (Mars) and the other is a Java IDE (Mars.2). I am interested in upgrading to Eclipse Neon for my Java IDE.
Would it be a good idea to uninstall my current Mars.2 version, or just install Neon on top of what I have?
Or, is there a another simple way to upgrade?
If the solution involves uninstalling my Mars.2 version, what files/directories do I need to delete so that my C++ IDE remains functional?
I apologize for the newbie question, but I wanted to get an expert's take that I can bring into my (hopeful) career.
Thanks.
No need to uninstall existed Eclipse since it's allowed to let multi eclipse run on the same machine.
If no big change has been made from original eclipse, I suggest just download a new version eclipse and unzip it to a different folder from existed eclipse folder based on instructions from FAQ How do I upgrade Eclipse IDE?
We strongly recommend against unzipping over your existing Eclipse
version as unexpected side effects may occur, including (but not
limited to): nausea, vomitting, shortness of breath, corrupt
installation.
You can then point the new Eclipse version to your existing workspace(s) and it will load with all your projects and preferences intact.
If your you have added many plugins and preferences to current Eclipse, please follow Easiest way to upgrade eclipse 3.7 to 4.2 (Juno) to migrate the plugins and preferences. Although that's a bit of a dicey process, since many plugins would be incompatible or need to be updated themselves. Better to just install whatever third-party plugins you use into the new Eclipse installation.
I wanna know how can I add Java Template Project in Xcode 4.
I'm working with Eclipse and it's really fine but i want to write Java program in Xcode.
Thanks for helping. ;)
Java is not a first class citizen of Xcode anymore, so you should in my opinion stay with Eclipse.
I realise this question is 6 years old, but I have a similar problem and found what seems an easy solution. I have an old Java project (2008-9) which I maintain but has been dormant. As I prefer to keep it into Xcode I transferred the whole project (sources, project files and all paraphernalia) to a new development machine running el Capitan with Xcode 7.3.1. I opened the project (which was still in 3.1 version) with it, and tried to build it. It failed as Ant was missing. So I downloaded Ant (version 1.10.1) and copied its bin and lib directories under /usr/local/ant, then I changed the project external build tool configuration (under project, go to Info, and you'll see that parameter) which was set to /usr/bin/ant and set it to /usr/local/ant/bin/ant or wherever you put it. Build again and this time it worked.
We have existing projects set with compilation dependencies in a RAD7 IDE.
Is it possible to create automated build script from the existing project structure?
We have IBM portal projects and regular WEB and enterprise projects.
Maven and Ant are possible solutions but can we use these tools to build existing projects
from command line without using the IDE itself?
Also is it possible to call RAD \ eclipse core compilation from command line or API?
Thanks
You need to look into "headless mode". That's basically running the IDE to perform its work without the IDE showing up.
I don't have any direct experience but one of the teams in our lab used RAD in headless mode to automate builds for an Eclipse/System-z interface.
You can find information on headless Ant builds in chapter 23 of the Rational Application Developer V7 Programming Guide Rebook. There's more documentation in the IBM Rational Application Developer Version 7.0.0.x Information Center (which you should also be able to find in the help).
There are a number of projects already using Tycho to build Eclipse components using Maven:
There is a somewhat dated tutorial for Tycho here: http://www.sonatype.com/people/2008/11/building-eclipse-plugins-with-maven-tycho/
For more information about the Tycho development effort: http://www.sonatype.com/people/2009/03/the-future-of-maven-osgi-join-the-tycho-users-mailing-list/
Based off the answer in Build Eclipse Java Project from Command Line. You can do the following
"%RAD_INSTALL%\jdk\jre\bin\java.exe" -Dwtp.autotest.noninteractive=true -cp "%RAD_INSTALL%\startup.jar" org.eclipse.core.launcher.Main -application org.eclipse.jdt.apt.core.aptBuild -data "%WORKSPACE%"
Where you configure the variables %RAD_INSTALL% to your instance of RAD and %WORKSPACE% to the workspace which houses the projects you want to biuld.
I have a question regarding the development of liferay portlets using the liferay plugin SDK. My question goes mainly in the setup of the development IDE. The suggested one would be to use Netbeans IDE which I also tried out, but it appears to run very slowly on my machine while Eclipse is quite performant.
The setup for Netbeans IDE is the following
Go to the directory \portlets
Run the create.bat (or sh file depending on the OS) to create a new sample portlet
Run Netbeans IDE, create a new "Java free form project" and point it to the directory of the created sample portlet
That's it, pretty simple.
For the mentioned reasons above (and because I'm a lot more familiar with Eclipse) I'd like to import the project into Eclipse the same way. Is there a way for doing it without having to change too much in the original structure of the created sample portlet and the according build.xml (ant file)?? I tried already to create a new project out of the build.xml ant file of the created sample portlet, however in this way it doesn't include me the source code.
I didn't also find great tutorials on the web...
Could someone help me with this, pointing out online tutorials or give me some hints.
Thanks
I know your pain. Starting to work with Liferay needs much time. I you do not want to edit the existing source, but only crate your own portlets, you can download the plugins SDK from the 'Additional Files' section on the Liferay website. This provides ant scripts, to create a simple JSR compliant portlet, and to create all necessary things, to create a sound Eclipse project, for example:
ant -Dportlet.name=<project name> -Dportlet.display.name="<portlet title>" create
Than cd into the directory of your created portlet an do:
ant setup-eclipse
After that you should be able to create a new project from the sources in that directory in Eclipse, which can then be deployed via another ant script to the running tomcat instance. If you already know somthing about portlet programming, you shoud be pretty much settled now. If not, try to find documentation about JSR portlet programming first, before looking into Liferay specifig portlet development.
Liferay has now released an official set of Eclipse plugins that support portlet development. Here is the installation guide for installing the eclipse plugins:
Liferay IDE Installation Guide
Also there is a getting started guide that shows what to do after installation to actually setting up your first portlet project.
Getting Started Tutorial
Liferay IDE uses the Plugins SDK from Liferay under the covers to do all the work. If you already have existing projects that you created with the Plugins SDK those can be imported into Liferay IDE as well.
Importing existing Projects
you can find the tutorial for deploying liferay in eclipse
http://www.liferay.com/web/guest/community/wiki/-/wiki/Main/Development+Environment+(Windows)
No clue about Liferay's specifics, but in general, I'd do this:
Follow the steps 1 and 2 from your NB setup list
Create a new Dynamic web project (or a Java project if you don't need the web project's features) in Eclipse
Import the contents of sample portlet directory by doing Import -> File system in Eclipse
Adjust the project's Java source directory to point to the generated sample portlet source directory (that should now appear in your project)
Adjust classpath of the project, point it to LR lib folders, ...
If there's a generated build.xml, check if it can be used to deploy to LR, or to produce builds.
As of March 2011, there is some official Liferay support for NetBeans and as noted before, there is official support for Eclipse ( In the Marketplace). The Documentarian uses Eclipse himself, though many examples just use the Plugins-SDK with shell scripts, ant scripts and no IDE.
We are fighting with Liferay on Eclipse, Eclipse seems buggy and unpredictable, but we are also new to J2EE and Eclipse ( so discount this last comment a bit), and I have our portlet files setup in a separate area for SVN, requiring a refactor-move, refactor is definitely buggy.
You should be aware that there is a book for developers on the way from the official documentarian - we've bought the early release and found it useful. He does cover some IDE issues. See Manning press.
The Liferay sample portlets ( there are many) are not set up for Eclipse projects, and you'll have to import some java files and jump through some Eclipse hoops to get them into a running Eclipse project you can develop.
