I'm wondering why I can't see following folders in src node in Package Explorer
src/main/java
src/main/resources
src/test/java
src/test/resources
I can access those folders as direct children of the project and they exist in the file system.
I'm using Spring Tool Suite (STS of Eclipse).
Maybe I can configure Eclipse somehow ?
I have solved this issue by below steps:
Right click the Maven Project -> Build Path -> Configure Build Path
In Order and Export tab, you can see the message like '2 build path entries are missing'
Now select 'JRE System Library' and 'Maven Dependencies' checkbox
Click OK
Now you can see below in all type of Explorers (Package or Project or Navigator)
src/main/java
src/main/resources
src/test/java
Eclipse filters out folders that are marked as source from the "raw" folder path. That is, they are visible only as source folders:
If you can't see them in either place, then they
are either filtered out in the settings: check your settings for Package Explorer (the Package Explorer bar, downwards menu arrow -> Filters...)
or they were created externally and Eclipse haven't noticed them: Refresh your project in this case.
or they don't exist: right-click on the project, select New->Folder and input the path, e.g. src/test/java (not "Source Folder"). After you use Maven->Update Project... on the project, they will be automatically added as source folders, provided you have the default configuration.
Now, as I said, those folder will only be used as source if you preserved the default configuration in your POM. If you defined other resources and/or testResources, those will be used instead. In general, Eclipse m2e synchronizes Eclipse's project source folder configuration with what's in your POM.
EDIT: maybe this is unclear - see those folders at the top? The ones labeled with the /-separated paths? These are your folders. These are the same folders that you would expect to find in main and test, just represented differently.
I used to get the same problem, but solved it by pointing to the right jre used for the project.
Right click on the project
properties
java builpath
see the jre selected
edit it
select alternate jre
installed jre
select the right one
ok
After changing right click on project>maven>update project
Hope it helps.
Attaching screen shot.
If you are looking for Simple/quicker way, you can follow this solution.
Right click on your project.
Goto > Build Path > Configure Build Path > Java Build Path
Goto 'Source' tab, there, you can see like <<your_project_name>>/src/main/java(missing).
Click on it and remove.
Click on Apply and Close.
Now, right click on project and >New > Source folder > add source folder "src/main/java".
happy learning and do not forget to upvote :)
I had the same problem, I changed my Eclipse project view from Package explorer to Project Explorer.
After 2 hours of trying everything...
Just go on window -> show view -> project explorer
and in project explorer you can view of all files solution
I had a similar issue when I checked out a web project from a github repo on my eclipse. src/main/java was directly inside the project root in Package Explorer. My expectation was that src/main/java be visible inside a source folder "Java Resources". There were few things which I did to achieve this.
Right click on Project > Build Path > Configure Build Path..
Select filter "Java Build Path" and click on Tab "Libraries"
Verify your "JRE System Library". If it is not pointing to your latest JDK, then you can click on Edit Button and follow the subsequent dialog boxes to select most appropriate JDK home path in your system.
Once done click Apply, Apply and Close, Finish to close all the associated open boxes for the current filter.
Select filter "Java Compiler" and ensure your JDK Compliance points to correct JDK. Click Aapply
Select filter "Project Facets". Ensure both Java and Dynamic Web Module is selected with correct version.
Click Apply and Close.
Source folder "Java Resources" gets created with src/main/java in it when viewed in Project Explorer.
Navigate > Show In > Package Explore
Right click the Maven Project
-> Build Path -> Configure Build Path
Go to Order and Export tab,
you can see the message like '2 build path entries are missing'
Now select 'JRE System Library' and 'Maven Dependencies' checkbox
Click OK

I used this tutorial to create my maven web project http://crunchify.com/how-to-create-dynamic-web-project-using-maven-in-eclipse/ and eclipse did not create src/main/java folder for me. When i tired to create the source folder src/main/java eclipse did not let me. So i created the folder outside eclipse in the project directly and then src/main/java appeared in eclipse.
I was not able to see the build path option in the properties as well. Also the
src/main/java
was not visible in Project Explorer. below solution worked for me
Go to Project root
Select "Project facets" from Properties
Check "Java"
This fixes the issue
If none of the answers worked for you. You might be in the wrong "Window". I was in "Package explorer" and switching to "Project Explorer" showed me the folders.
Right click on the project > Build Path > Configure Build Path > Source > Add Folder > Select src/main/java > apply and close > refresh the project.
This error happens when there are no files inside /src/main/java
Just make some empty files inside and the problem will go away.
A side note: lots of version control systems (mercurial for example) do not commit folders if there are no files inside.
After creating the project go to properties --> build path --> configure build path --> order and export tab and check jre and maven dependencies. You will then have the folder.
Right click on eclipse project go to build path and then configure build path you will see jre and maven will be unchecked check both of them and your error will be solved
My problem was kind of the same at first and then a little different in the sense that when /java folder showed up, it was deep down in a nested folder somewhere in src/main/resources/java.
Initallially the problem was being in the Package Explorer and not in the Project Explorer as many people have talked about. So,
a. right-click on your project root
b. show in, and select Project Explorer
However, the main problem was I missed to notice a checkbox at the second step of Maven Project Creation from the wizard. That got me created a complicated structure and not a clean direct one.
Once I marked it checked I got a clean project structure as what asked.
I was also facing the issue but I open POM xml file and keep it open. Wait for some time till maven read pom then Automatically it will come.
I tried all the solutions mentioned in this post but none of them worked for me.
The solution for me was to go to build-path and then into Source tab. I found src/main/java folders present there and there was no error. I double clicked on this folder and a window opened like this:
Do not make any change and click on Finish. The folders will appear suddenly.
In eclipse the Open Resource window (Hot keyed to Cmd+Shift+R) to open a file by typing its name seems to show *.pyc files despite the Navigator view correctly hiding them.
Is there anyway to set this up to ignore PYC files?
I have looked at the following links and it appears that pydev may require a src folder underneath the main eclipse folder. I do not have that structure however the full project has been marked as a 'source' folder in Pydev - PYTHONPATH under project properties.

http://pydev.org/manual_101_project_conf2.html
I found the solution!
CMD+i on the project folder (or "right click" -> properties), then:
under "resources" -> "resources filters":
click "add"
choose "exclude all"
select "files and folders"
check "all children (recursive)"
type *.pyc in the text field at the bottom
ok
ok

I'm getting an issue where non-src folders are looking like packages, they look completely fine in my natural folder directory.
The assets folder should be a hierarchy, but isn't.
Thought it was because I was in package explorer but not project explorer, same issue with project explorer.
I believe, you right click on your project and choose "Build Path" and "Use as source folder". If it is the case, you can revert the problem by right clicking on your project and selecting "Build Path" and then "Remove from build path".
For me the following worked (in RAD actually): Go to "Project Properties" / "Java Build Path" and mark the Resource Folder as "Source folders on the build path".
The Resource Folder (here, src/main/resources) appears as filled with classless packages:
Enter the exlcusion pattern "**" to exclude any source path:
This solves the problem.
Maven Update fixed my problem easily.
Right click on project,
maven->Update Project
I suspect that the cause was I run maven commands from command prompt (cmd) directly.
If your simple folder is turning into package format. Be clear that it is not source folder, it is just simple directory like "docs" you want to keep in your Project but eclipse is turning it into Package format. then do below step:
right click on your package -> Build Path -> exclude
I am using Eclipse/Texlipse plugin and if I create a new project Texclipse
automatically creates a folder called "Search Paths". You are not possible to do
a right click on that folder to get to the properties etc. I was wondering whether it is
possible to somehow hide that folder as it just includes the paths for the latex compilers etc.
The "Search Paths" folder is only virtual and is not created by TeXlipse on the file system. Furthermore, it is solely shown in the "Project explorer" view. You can use Eclipse's "Navigator" view instead, which is similar to the "Project explorer".
In Java projects in Eclipse version 3.4.1 sometimes the folder "Referenced Libraries" disappears from the "Project Explorer" view. All third party jars are shown directly in the root of the project folder. The project compiles and runs fine. It seems to be a GUI problem.
How can I get this folder back?
First, bring up the "Package Explorer" view (instead of the "Project Explorer" view).
Then, if the referenced .jar files still are visible in the root of the project, click on the little "down arrow" icon in the top-right corner of the Package Explorer view. In the context menu that appears, one of the items on the menu is "Show 'Referenced Libraries' Node." Click on that menu item.
I've been struggling with this thing for a while in Eclipse Juno because it's a little bit different.
click the little down arrow as before
click Customize view
check Libraries from external
For those hitting the issue today (Kepler): it is possible that you are in the "Java EE" perspective, which by default has the Project Explorer. Simply switch to the "Java" perspective and it will replace Project Explorer with Package Explorer, which will have the missing Referenced Libraries folder.
Make sure you're actually in Project Explorer and not in some other view like Navigator, like my friend was...
Use the Package Explorer view instead of the Project Explorer view.
