I'm a using Netbeans 8.1 to code in Java, when I want to add an external library (such as XStream, JDateChooser, etc) I find the .jar online and I add it to my project through the right clicking in Libraries --> add JAR/Folder.
After this I write my code and everything works fine until I finish my project and I want to export it into a .jar with Clean and Build
I think this maybe because I give an absolute path to the libaray instead of a relative one but I'm not sure.
PS: The library that I'm having trouble with is XStream 1.4.7
All the libraries included should pack in a jar file after build. The simplest approach is to click right on your project, select Properties and The project properties. In the new window opened find Categories and Libraries. The in the right side you may see the button Add library/JAR. Probably it's the same way.
Also you can create a Maven project and import all the libraries through dependencies.

I am just starting with JavaFX and for some reason, Eclipse does not suggest to import JavaFX stuff so I have to type it in manually. Example: javafx.scene.Group I typed in Group as a type and it suggested other things such as javax.swing.GroupLayout.Group
image of suggestions
I'm not exactly sure, but I think maybe the fact that the JavaFX library is under Modulepath instead of Classpath has to do with it, but it only works if it is under Modulepath.
Help would be greatly appreciated, thanks!
I'm rewriting this answer, as #kleopatra pointed out it was inexact
For suggestions to work, you need to have JavaFX on your project's build path.
If you've created a plain Java project in Eclipse, with a module-info.java at it's source path root, then you need to add all the required jars to the module path:
JavaFX SDK should already be installed on your system, or download it from Gluon and unzip it
Right-click your Java project, got to Build Path -> Configure Build Path...
Go to Libraries tab, point to the Modulepath section
Click [Add External JARs...] button, pick all the jars from JavaFX SDK, hit [Apply and close]
Then suggestions should work as expected, and imports will be automatically inserted at the top of your java files, but they will appear in error the first time you import anything from a given library module, as this module must also be required in your module-info.java. You can do that automatically with a quick fix ("Add 'requires javafx.something' to module-info.java") when hovering the import.
Now there's a more straightforward way to create a JavaFX modular project in Eclipse, using Maven:
Create a new Maven Project
Check and pass the first wizard screen
Select archetype org.openjfx:javafx-archetype-fxml
On the next screen, you can select the JavaFX version of your choice (currently 13 by default)
After the wizard terminates, you've got a nice little project already setup with an application window and two FXML sample displays. You can start from there to build your own project.
I am working on a project where i need to know the contents of jar file included in my web-project. I am using Eclipse juno. However Netbeans provides these features to view the contents of a jar-file. Please suggest me how to achieve this in eclipse.
In the project explorer, you should have something with an icon looking like a pile of book like those:
just expand the one containing your dependencies (probably labelled "Referenced Librairies") and you can browse as usual.
NB: you will probably need to specify where the sources are for each jars (right click on a jar > Properties > Java source attachment)
[image is courtesy of JBoss community]
Please use the Eclipse plugin zipeditor in order to view the content of jars, zips or wars: Enter update site: http://zipeditor.sourceforge.org/update and enjoy. That is the best choice so far to handle archives in Eclipse.
The jar will need to be added to the build path in the libraries tab, if it isn't already, in order to be viewable under referenced libraries
I'm currently trying to learn to use Guava so I downloaded the source by doing this:
svn checkout http://guava-libraries.googlecode.com/svn/trunk/ guava-libraries-read-only
Sorry if this sounds really stupid but for the life of me, I can't figure out how to load up the source in Eclipse to examine it. I've tried different ways (creating, importing, etc) but always end up with package problems.
I'm using Eclipse 3.5 on Ubuntu by the way.
Can I get some help on this? Thanks!
EDIT: I'm trying to examine the source so I would like to add the source as a project.
Here is what I would do...
Go to the downloads page and grab the latest bundled release
Unzip it to some local directory
Copy the guava-r<version>.jar to your project's lib directory.
Right click on the JAR from Eclipse and say "Add to Build Path".
If you need the source you can attach the guava-r<version>-src.jar in Eclipse via the Configure Build Path project menu or by using the attach source button during debug.
It's easiest to download a Jar from the Guava site, copy it into your Eclipse project and add it to the build path using the jar context menu > Build Path > Add to Build Path. Also, point Eclipse to the included source zip using project context menu > Configure Build Path... to get Javadoc on the Guava classes.
I have done it two ways: the Subclipse and Maven eclipse plugins. Both offer "create project from repository"-like options. Both plugins have reasonable online help, so I'll not repeat exact steps here.
Creating a project from the repositories will give you a full view of the source (and documentation, build files, etc).
I might be a little late in answering ... but you could also simply install the guava bundle from the update site "guava-bundle"; it will install the sources along and you'll then just have to import the plugins in your workspace (File > Import > plugins and fragment... don't forget to tick the "projects with source folder" checkbox on the first page of this wizard) and browse the source from it.
Note that this update site has now been discontinued in profit of Guava-osgi which also provide an update site for easy installation ... but I haven't installed it yet and thus don't know whether the sources are included in the artifacts installed through this update site.
I've downloaded the ANTLR Java runtime libraries. It's a jar file. It contains "org.antlr.runtime". Where do I put it so that the Java compiler can find it? Do I need to extract it? I'm using NetBeans (for now), if relevant.
Assuming you can find your jdk folder, You can move the .jar file into the jdk\jre\lib\ext folder, where other .jar files are placed. After doing so, NetBeans should be able to run files with access to the library
For NetBeans you go to your Projects Tab and then right-click on the project you want the library added to then click Properties. Go to the Libraries bullet then on the right side click on Add JAR/Folder. No need to extract it. All you have to do is right click in the editor window and click Fix Imports.
For use outside of NetBeans you have to add it to your Java classpath.
For java command line you need to add it to your class path however in Netbeans you just need to add it as a library. It can be anywhere. Google to find out how to do these things.
In fact in netbeans, you can just say you need this in your maven project and it will do the download of the jar and its source/documentation as required.
I have just started playing with Java, and I really like the language. I am using the NetBeans IDE, and I find one odd oversight. I can create a new class in a project, but NetBeans doesn't appear to support any way to import an existing class into a project.
I manage to get it done by going to some other project where the desired class already occurs, and then I copy/paste it into the source code folder of the new project, then change the package name at the top of the pasted file to match the package name of the new project.
Is there a nice direct way to do this from the NetBeans interface?
Thanks for any help on this.
In the Projects window you can expand the project that you are working on. Right Click on Libraries and select Add Project.... You will get a dialog allowing you to select another Netbeans Project with the Java classes that you wish to use.
You have to just make the .jar file of that/those java files which you want to use in another project.
right click on file->export->java->.jar then finish.
Now you can use these jar into your another project.
When you build the java project in netbeans it creates a jar file on the dist folder in the current project directory.
You can use this jar file for the other project as a package by adding this as ADD jar in the next project.I have tried this ,i am using my old project jar file for new project development.
Use the 'Clean and build' your project option from the netbeans application, that creates the 'dist' folder which you are looking for (and obviously can't find because you havn't cleaned&buld)
The netbeans itself creates .jar files and you can add the jar file to the current project you are working on.
