I have several modules of a project and i have made each module as a project in eclipse as a seperate project..
Now i want to combine those projects in a masterproject..
Is it possible to do it?
thanking you in advance!!
Right Click on project. Go to build path->Configure build path->Projects. here you can add any project (which is already in eclipse) on the build path.
Yes. You can easily set things up so that one project uses other projects. Simply right click on the project in the package explorer, then click Build Path, then Configure Build Path, then add Project. Voilà!

From time to time, Eclipse (Indigo) complains that certain classes in my projects cannot be resolved to a type. Even it shows the class in popup list, clicking import (see image) does not add the import statement! Even if I add it manually, it doesn't recognize it (and underlines the import package).
This happens only in certain projects.
Unresolved types are in the same project! (not in other dependencies)
cleaning the project does resolve this, but only temporarily.
My application consists of multi-module maven based projects.
All projects are maven-based.
Not recognizing imports
Right click on your project name ->Maven ->Update Project
For those not using Maven, simply deleting the project (and possibly re-cloning it) has reliably worked for me.
This just happened to be in Eclipse Neon.2 (2016 release) on a non-Maven project. Refreshing / updating the project did not help, but I was able to fix this without recreating the project:
Go to Properties → Build Path → Source
Remove all source folders in the build path, click Apply.
Add them all back, click Apply.
Right click on the project -> Maven -> Update Project...

I have two workspaces and I want to use java file as a parent class or you can say extends it from workspace2 to workspace 1 in eclipse, how can I do this?
As I can add project from same workspace but unable to figure out from different workspace.
I dont want to import the project.
Thanks in advance
You can make New File -> advanced options and Link to Folder in the system where the class is
You need to import your project from workspace 2 to workspace 1.
You can reference your project in another workspace in the build path configuration of your project, linking two eclipse project, even if they are in different workspaces.
If you want the code to be available for changes this are your options:
You have to either import the project or create a new workspace that includes them all.
Note that you may extend the java class from the same project or from another project within the workspace, but not from another workspace.
If you are willing not to have the code in front of you available for changes, you may build the first workspace' project into a jar and then use that as part of your other workspace.
Way 1
You can add the second project's src folder to the current project and you can add them in your project.
Right click on project -> Build path - > source tab - > link source
Way 2 :
Make that external project as a jar and add as a dependency.
I'm switching to Intellij and trying to do the same thing as in Eclipse. In Eclipse, you can add a project as a dependency in another project (project properties -> "Java Build Path" -> "Projects" -> Click on my library project).
The current situation is that I'm developing a library and I can test the features in another project without building the jar file every time I add new stuff to the library.
I'm trying to achieve this with Intellij but without success (the projects are both imported in Intellij).
How can I do that?
File > Project Structure. Then choose your module, and add any dependency, either Jar, Library or Module:

From File -> project structure, select Modules. You will be presented with all the added projects. Click a project and from the right hand side select Dependencies tab. This will show you projects that are not imported in red coloured text. HTH
File > Project Structure > Project Settings > Modules
Add the module you want to add as dependency.
Add your module dependency in your project.
If you use Maven you'll see the following message:
Module 'your-module' is imported from Maven. Any changes made in its
configuration may be lost after reimporting.
→ Add your project to your pom.xml
If you don't do that, your dependency will be removed each time you reimport/refresh maven projects.
I want to ask something. I have done three small projects on Java at Netbeans. Can I make a project which it calls theese three projects ? I want to have all theese projects in one programm. Thank you !
Basically, yes.
Expand the "master" project and right click on the "Libraries" node.
From the popup, select "Add Project". Browse to the location of the project you want to link and select "Add Project JAR Files".
The project will now be linked to your project and you should be able to access it's classes.
Note, if the child project has any dependencies of it's own, you will need to add those to the "master" project as well.
You can either add those projects into your new program build path or make the libraries and use it.
I am trying to import maven project into eclipse 4.2 version.Its not importing the project properly. Its giving me error "Source folder is not a Java project" while I am trying to create a new call in it. Even ctrl+mouse click is also not working. I don't understand the problem. Even when I right click on project and select build path it shows me no action available. Anyone face the same issue
In the maven project directory try
mvn eclipse:eclipse
that may do the trick.
I ran into the same issue and fixed it by converting my project to faceted form.
Right click your project > Properties > Project Facets > Convert to Faceted Form, and select Java.
I had the same problem... But you just need to update "source Folder" to correct source "src/main/java" from whatever mentioned in the pop up:
[]
Either turn your project into Eclipse project, using mvn eclipse:eclipse, or install Maven Integration for Eclipse plugins, like m2eclipse, and import project as a Maven project.
I got the same error in a slightly different context (Indigo with m2eclipse):
I imported a multi-module (1 jar module and 1 war module) maven project into Eclipse. Everything worked fine (clean, install OK) until I tried to add a new class to one of the modules and got the "Source Folder is not a Java project" error.
I solved this by opening the properties on the parent project and selecting the following Project Facets:
Java
Dynamic Web Module
This solved the problem. My guess is that, because the parent project for a multi-module project has pom packaging (<packaging>pom</packaging>), Eclipse doesn't know what kind of projects the parent project encloses (i.e. if the packaging were jar, it would know that it's a java project; if the packaging were war, it would know that it's a static or dynamic web module, etc.)
This is just my guess, but the fix worked for me, and it makes sense.
for those who already see java selected, uncheck and check it again.
select apply to override the existing setttings. finally it works !
Right click your project > Properties > Project Facets > Convert to Faceted Form, and select Java
Right click your project > Maven > Update Project
This step will add your project so the issue resolves easily.
mvn eclipse:eclipse
will resolve this problem. convert to maven project.
I had this error because I tried to create a new Project by doing "Ctrl+N", typing "Project" on the Wizard's input label and then just pushing "Enter" until it was created.
I solved this by typing "Java Project" instead of just "Project".
You can also create a JAVA PROJECT by going to File > New > Java Project.
open cmd and run the following command in the folder of your project-
mvn eclipse:eclipse
This did the trick for me
If you are having maven project and you are getting this error. You can follow below steps.
Right click on the project and select properties.
Then click on Project Natures
In the dialogue box, click on Add and in the warning click on OK.
Filter java in the popup box and click on OK.
Click on apply and close.
It will add java nature to your maven project and you will not get this error anymore.
Right click your project > Properties > Project Facets > Convert to Faceted Form, select Java, and apply&close
