So for my class I need to use eclipse to do some graphics stuff in Java. I've tried both Eclipse standard 4.4 and Eclipse for Java developers, but with both when I tried to create a new Java project, the src folder is completely empty. Why is that?
Edit: I should add in more information. In the lab section of my class I was able to follow the instructions and create a lab 1 project src folder, which contains many files such as Lab1.java, Polygon1.java and all that. When I am trying to do it on my own machine, it's not working
Because it's a blank canvas!!
Right click on the src file New->Class
Give the new class a name and a package and you're away, you can start coding.
If you want to include libraries create a new lib folder at the same level as the src folder and copy any jar folders into this folder. Right click on the .jar files and click Bukd Path->Add to Build path, you'll now be able to import and classes contained in this jar file(s)!!!
Because you created a new project. If you haven't added any code yet, why would there be code in the src folder?

This may be a dumb question, but I am having trouble creating a haskell module in eclipsefp. I can open the HaskellModule wizard but if I click browse next to source folder there is nothing except my project. My project has folders on it but they do not appear on the dropdown.
You need to define what source folders are in the Cabal file for your project. By default this may be the root folder, this is why you only see your project. In the cabal file say that your source folders are some of your sub folders and you should see them available in the wizard.
Bu default a new EclipseFP project uses src as a source folder, not the root.
The team in which I'm working doesn't use eclipse and wants the src folder to be setup a certain way. I, on the other hand, am using eclipse. They would like the src folder to have, for example, the following structure: src/main/java/com/* However, they would like package declarations to only have com.* in them. If I go to project->properties and in the source tab remove the src folder as a source folder and then _only add the com.* folder as part of the source_ it will show com.* as a package, but I still have to add the whole path from src down in the .java files. Here's an example of what I have to do in order for eclipse to recognize the packages:
package main.java.com.parser;
And what the team wants is to have main and java just be a folder so the package declaration would just be:
package com.parser;
So although the file structure would still be src/main/java/com/parser, the package name would be as stated in the later example.
Is there a way to do this in eclipse? I've seen some people asking similar questions on here, but they seem to have no concern that the whole path must be part of the package declaration.
I would much prefer not to do this this way, but no one else is using eclipse on this project.
Thanks for any help in advance.
In the Package Explorer, right click the src folder and select Build Path > Remove from Build Path
Then find the src/main/java folder, right click java and select Build Path > Use as Source Folder
Basically this tell eclipse that java is the folder which contains the packages and source files.
P.S. This is a very normal project setup for building with Maven. If you download the m2e (Maven to Eclipse) plugins and choose to create a Maven Project (or import from the pom.xml) then Eclipse will automatically know how to correctly locate the source folder.
I just recently downloaded the dom4j library, but for the life of me I have no idea how to access it. I dropped it in the plug-ins folder and rebooted Eclipse, without success. For some reason finding a straight answer for this is more difficult that I thought it would be.
No, don't do it that way.
From your Eclipse workspace, right click your project on the left pane -> Properties -> Java Build Path -> Add Jars -> add your jars here.
Tadaa!! :)
Extract the jar, and put it somewhere in your Java project (usually under a "lib" subdirectory).
Right click the project, open its preferences, go for Java build path, and then the Libraries tab. You can add the library there with "add a jar".
If your jar is not open source, you may want to store it elsewhere and connect to it as an external jar.
For the Android library projects, I do it as in the attached screenshot:
Right click the project, select Properties->Android and in the library section click Add. From here you can select the available libraries.
If you are importing a jar file, then importing them as jar or external jar, as other posters posted would work. I prefer to copy/paste jar file in the libs folder (create one if it doesn't exist) and then import as jar.
If you want to get this library into your library and use it, follow these steps:
You can create a new folder within Eclipse by right-clicking on your project, and selecting New Folder. The library folder is traditionally called lib.
Drag and drop your jar folder into the new lib folder, and when prompted select Copy Files.
Selecting the Project tab at the top of the screen, and click Properties.
Select Java Build Path followed by the Libraries tab.
Click the Add JARs… button and select your JAR file from within the lib folder.
Your JAR file will now appear in both the lib and Referenced Libraries folders. You can explore the JAR's resources by clicking Referenced Libraries.
I have a project I am working on. I have decided to try working with it in Eclipse. There is already a directory, under version control where all the code resides. I am having a rather strange problem. I cannot find any way to just start using an existing code directory as an eclipse project. All I can find is how to import existing source into a new project or check out source from version control into a new project. How do I make an existing directory into a project?
My project is a Django web app if it is any help
In the New Java Project wizard, uncheck the checkbox that says Use default location and the use the Browse button to find your directory.
It is pretty easy to do. Go to File->New-> Project. In the Project wizard, choose the type of project you want and then be sure to unclick the 'Use default location` checkbox. Browse for your folder in the widget that then becomes enabled. Click finish after that.
Alternatively, you could create a brand new project workspace in a new location. Then, assuming Java as your project type, you can open up your project properties and add as a source folder your existing directory. To do this, use the 'Link Source' button on the Java Build Path -> Source tab of your Project Properties dialog.
My Method:
I clone this file to new project directory , and rename Project-Name to my project name, after that i import new files and directory from Eclips
File Name: .project ( Use Notepad for make this file...select Save as type to All Files (*.*) and write file name like: .project )
<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
<name>Project-Name</name>

Creating linked resources
Folders and files can be linked to locations in the file system outside of the project's location. These special folders and files are called linked resources.
To create a linked folder:
In one of the navigation views, right-click the project or folder where you want to create the linked folder.
From the pop-up menu, select command link New > Folder.
Specify the name of the folder as it will appear in the workbench. This name can be different from the name of the folder in the file system.
Click Advanced.
Check Link to alternate location (Linked Folder).
Enter a file system path, or click Browse to select a folder in the file system.
Click Finish.
Probably not the way most people would go about this, but I like all of my eclipse projects in one place but don't necessarily have my source in my workspace directory. Maybe there is a built in way to "symlink" in eclipse, but I sometimes end up with the project folder in the workspace, with the "src" symlinked to the actual source directory somewhere totally different. That's my personal preference anyway. If you too are on a *nix machine a simple
ln -s /path/to/source src
will do from your project directory.
You know, it is not so simple question. Depending on your project type (jar, web module, ear and so on) different structure and configuration files are used by eclipse. So the first really interesting question is that what is your project type? The basic solution after it to create a new project, and define the directory of your source code as project root. Then you will see what else to change (for example source path settings, classpath and so on). So how does your project look like? Can you proide structure tree of folders?
Since you are using Django you should first set up PyDev in Eclipse. You can install it from the market. Then you want to configure the PyDev Python interpreters to find your installation of Django (http://pydev.org/manual_101_interpreter.html). Make sure to provide the explicit path to the Django folder if your Django is not installed in the default location.
Once these things are ready you can select File > New > Other, then select PyDev Django Project from the PyDev sub directory.
Click next and here is the sweet part: Uncheck 'Use default' (as previously stated) and then find your Django project directory. Be sure to select the right project folder (ie: the folder that contains manage.py). When you have the right folder selected Eclipse/PyDev will recognize that a project already exists and make mention that it will use those files. Click Finish.
Then there is a DB form that asks about your DB settings. If you already have a settings.py file then this seems to make no changes (as it should not). So fill it in or don't. But this is the last step.
Then you should be able to view and use your existing project in Eclipse!
I just created a pom.xml by hand and imported the project as an existing Maven project in Eclipse. It even works for nested projects without problems.
Use "import - existing projects into workspace". This works for my case.
Right click on a project -> Properties.
Open project location in explorer, there's a little icon next to path.
Put your folder/file structure in there and refresh the project in eclipse.
I have been moving my Java projects from Jdeveloper over to Eclipse whenever I have to go back and make a change (I only work with Java projects sparingly).
Everytime I try to create a project in Eclipse (3.3.2) I spend quite some time trying to figure out the proper way to configure the source directories in the Java build path dialog.
The biggest problem I'm having is getting the source directories to match up with the package specified in the source files. For Example my project looks like this:
MyProject
DevelopmentBuilds
MainSRC
The MainSRC directory is also the "Root" package so my classes would be defined as:
package MainSRC.Sub1;
If I set my included directory to blank, the files compile but with many errors because the Packages are not in the right place.
How do I tell eclipse to start at MainSRC for the compilation rather than the children of MainSRC?
Or, should I the path up with one src folder with MainSRC as subfolder?
I basically don't understand how this works.
you need to set MainSRC as a 'Source Folder'.
Apparently, you project root are set as Source Folder.
Enter in project properties:
. Right click over your Project root, and select Properties
. Choose Java Build Path
. Remove all source folders
. Click 'Add Folder'
. Select 'MainSRC'
. Click Ok and Ok
Now, your MainSRC are a Source Folder. Some error occurs inside source files. For agile process, right click over package 'Sub1', and press F2. Rename your package for a new, then all your source files will be put in the correct new package.
[]'s,
And Past
You would need to set the source directory to the root MyProject directory. You would have to tell Eclipse to exclude the other directories (such as DevelopmentBuilds) as they are not source code.
You might find you're better off conforming to Eclipse's expectations and creating a source folder which contains your main package folder.
