Java EE. Maven.
Package resources marked as Resource root, package java as Source root also.
In my class I have path String property\file.properties, but when I run it, IDEA throws an exception :
"java.io.FileNotFoundException: property\file.properties (The system
cannot find the path specified)"
But when I change path String to src\main\resources\property\file.properties it works.
Packages marked as source. In Project File - Module I also see that this directories marked as source roots.
How can I fix it, any ideas?
I have already tried invalidate cache.
P.S: When I rename my string path with shift + f6 file also change name.
EDIT:
Source root packages
In IntelliJ IDEA Ultimate as whereas the Community Edition, you can mark any folder in your project as your Sources, Tests, Resources, etc directory.
Right-click on your project root directory ➡ Select Open Module Settings in the context menu.
In the Project Structure window that opens, choose a folder in your project ➡ then select to 'Mark' that folder as your Sources or Resources directory depending on your needs.
You should see a list of marked folders in the right pane of the same window. Click the Apply and OK button when done to save your new changes.

I'm developing intellij plugin and I have tree structure with files and directories (not related to current project nor file systems). Is is just some virtual tree structure provided by rest service. I want to display it in ToolWindow with all common staff like colors, file type icons etc.
Is my usecase already supported by intellij?
Which classs support this?
The closes one related to my case I found trees from vcs package but it is commit / change related.
I don't think what you want to do is formally supported by JetBrains, but you could create a "fake" project in Intellij IDEA as long as the files and directories you want to appear in the tools (Project) window have a single parent directory.
I had a folder named "docs2" which contained some random notes and documentation files of various types such as txt, pdf, zip, html, js and bak. I opened that directory as a project in Intellij IDEA's Project window as follows:
Create an new project: File -> New -> Project... -> Static Web -> Static Web, then click the Next button:
On the next screen populate the Project location field by navigating to the folder containing the files you want to open in Itellij IDEA, and give the project a suitable name. Then click Finish.
After that Intellij IDEA will treat the directory as though it was a static web project.
Notes:
Intellij IDEA won't necessarily be able to handle all of the project files created in this manner. For example, when I opened a pdf file it was opened in another application, and when I tried to open a zip file nothing happened. But other known file types such as *.txt, *.html and *.js can be opened and edited as though they were files in a "real" project.
When you open the directory as a project Intellij IDEA will create some files in that directory: a *.iml project file and a .idea folder containing configuration files, so you will need write access to the folder that you open as a project.
I also tried opening the directory as an Empty Project in Intellij IDEA, but that only worked partially; files under the parent directory were shown, but for some reason it would not show any sub-directories in the project.

IJ recognizes main.java as a package, not a normal folder.
This is maven project.
How can i solve this problem?
You have incorrectly marked src as a source root (notice that is is blue) - right click and "unmark" it as a source root.
Then, locate the src\main\java folder and right click on the java folder -> mark as source root.
Once you have done this, intellij should recognise your folder structure correctly.
You might also want to mark resources as a resource root.
I have some java source code. It an just an archive which is four folders.
Folders MAIN, DATA, TAGS, USER_INTERFACE. Each folder contains a few class files.
I see how everything works together, but can't see to get the program to import correctly or run. I did find a MANIFEST.MF.
What is the proper way to import such a project?
Create an Eclipse project. Under the project settings, select the "Java Build Path", and add each source folder (and remove the default src folder that Eclipse may add for you).
If necessary, you may set the output/build folders for each source directory, and clear Eclipse's default bin output directory. Check the "Allow output folders for source folders" to enable this, then set each source folder's output folder.
(You may or may not want to keep compiled classes in individual directories.)
If there are class files in the project that aren't generated from source in the project, in the same dialog, select the "Libraries" tab, and click the "Add Class Folder" button to add dependencies from within the project.
It doesn't seem that your source code is an eclipse-importable project (it would have to have a .classpath and .project file in the top level directory for that).
You should instead create a new Java project. For simplicity, set the project's location to be the parent directory of your MAIN, DATA, etc. directories. Then after the project is created, configure a source folder for each of MAIN, DATA, etc. (right-click the project, choose Properties > Java Build Path, then work in the Source tab). Your source folders should then show up in the navigator and the project should be able to be compiled.
Create a hello world project in eclipse and understand the project structure in eclipse.
And then manually import the files it is simple and avoids a lot of confusion especially for somebody new to the environment.

Eclipse: The resource is not on the build path of a Java project
(16 answers)
Closed 5 years ago.
I am getting The resource is not on the buildpath of the project when I am trying to "Organize imports" or trying to access any class properties.
I am building my project with ant.I tried to configure my buildpath in javabuilpath -> Projects but it is not showing me my src folder there.I am not able to use quick assist (ctrl + space) and class related properties because of the same reason
and it does not show me any syntax errors also while i am writing my code.
please help me.
thanks
I just hit this problem myself, and it's baffling. You get it in a bunch of different places as you try and treat a Java file as, you know, a Java file but Eclipse hasn't figured out that it's actually a class within your project. The reason it doesn't know (or the reason it didn't know in my case) was because the directory hasn't been marked as a source directory for the project. So you need to tell the project configuration that the file is in a directory that holds source files. Here's how:
Open your project's properties.
Under "Java Build Path", click on the "Source" tab.
Click "Add Folder..."
Find the folder where you have the unrecognized java file. (In my
case it was test->Java)
Put a check by the folder. (I put it only by "java" and not by
"test" given that the test folder holds a lot of other stuff.)
Click ok, click OK again, perhaps refresh, and you should be good to
go.
Your src folder shouldn't appear in the Java Build Path -> Projects tab. Rather, it should appear under Source tab.
Try imorting the class files as external jar.
What icon is used for the file? If it is an outline J eclipse doesn't recognize the file as being a source file of the project.
If so, you need to declare the parent folder of your package a source folder, i.e. if the path looks like ".../src/my/package/MyClass.java" the "src" must be declared a source folder (right click -> Build Path -> Use as Source Folder)
I have created several .java files. All of them are located in one directory. I used a text editor to write these files. Now I want to switch to Eclipse. How can I do it? I have tried many ways. None of them works.
ADDED:
I think the common way is to have source in the eclipse folder called "workspace". So, how do I get my files in these directory. Should I use eclipse to create a new project from existing source and Eclipse will put all file to the workspace? Or I should manually copy all my files to the workspace? Where should I put my class files than? Should I create a subdirectory? With which name?
ADDED 2:
When I try to create a project with name "game", the eclipse writes me that a project with such name already exist. But how can I open this project?
ADDED 3:
In my "workspace" I have created a subdirectory called "game". I copied all my .java file into this subdirectory. Then with Eclipse I created a new project with the name game. As a result, Eclipse created .classpath and .project files in the directory "game". It also created bin and src subdirectories. And now I think it is not the correct way to go. The source files are supposed to be in the "src" directory. Right? And at the moment all my .java files are in the "workspace\game".
ADDED 4:
I did it other way around. With Eclipse I have created a new project with the name "game". As the result, Eclipse created a folder called "game" into folder "workspace". In "game" the folder I found "src" folder. I copied all my .java files into this folder. But now in the "Package Explorer" I cannot open "src" folder. So, how can I access my source files from Eclipse? Why Eclipse does not want to open the "src" folder?
Easiest Method:
Put all source files into one directory named after your project. i.e. "ProjectName" You can keep this directory in your workspace or it can be somewhere else.
Start a new project in eclipse and name it using that same project name.
Uncheck the "use default location" box and find the directory where your project is unless your project is already in the workspace - then you must not uncheck the "use default location" box
Click 'next'.
Eclipse should be smart enough to figure out what's going on. After clicking next, it will show you all of the files it found in that directory. It will just automatically add those files to your project. Voilà!
Right-click in the package explorer and select New - Java Project
Create the new project Game
Open the new project in the package explorer - you should see only the source folder called src (there's nothing inside yet)
Open a file Explorer (e.g. Windows Explorer) and drag your sources
Drag them to Eclipse and drop them inside the new src folder - if asked select "Copy files"
Eclipse should put the files into the default package, if that's not correct you can edit the offending files (marked with a red cross) by opening them in Eclipse, selecting the package declaration (usually line 1), pressing Ctrl + 1 and selecting the appropriate option (e.g. "Move xy to package com.game"
This answer is going to be for the question
How to create a new eclipse project and add a folder or a new package into the project,
or how to build a new project for existing java files.
Create a new project from the menu
File->New-> Java Project
If you are going to add a new pakcage, then create the same package name here by
File->New-> Package
Click the name of the package in project navigator, and right click, and import...
Import->General->File system (choose your file or package)
this worked for me I hope it helps others.
Thank you.
The easiest method is really good but you don't get a standard Java project, i.e., the .java and .class files separated in different folders.
To get this very easily:
Create a folder called "ProjectName" on the workspace of Eclipse.
Copy or move your folder with the .java files to the "ProjectName" folder.
Create a new Java Project called "ProjectName" (with the Use default location marked).
Press <Enter> and that's it.
There are two things
1- If its already a Eclipse Project, then simply go to File->Import->General->Existing Project into Workplace
2- Otherwise define project type e.g. Java, Web etc
Create a new project of type you define into your workplace. Copy Paste source , lib and other necessary files. refresh, compile and run project in eclipse.
In the package explorer and the navigation screen you should now see the project you created. Note that eclipse will not copy your files, it will just allow you to use the existing source and edit it from eclipse.
There are several ways to add files to an existing Java project in Eclipse. So lets assume you have already created the Java project in Eclipse (e.g. using File -> New -> Project... - and select Java project).
To get Java files into the new project you can do any of the following. Note that there are other ways as well. The sequence is my preference.
Drag the files into the Navigator view directly from the native file manager. You must create any needed Java packages first. This method is best for a few files in an existing Java package.
Use File -> Import... - select File System. Here you can then select exactly which files to import into the new project and in which Java package to put them. This is extremely handy if you want to import many files or there are multiple Java packages.
Copy the fires directly to the folder/directory in the workspace and then use File -> Refresh to refresh the Eclipse view of the native system. Remember to select the new project before the refresh.
The last one is what you did - minus the refresh...
While creating a project from a full folder may or may not work within the workspace, there's a condition outside of the workspace that prevents starting a new project with a full folder.
This is relevant if you use numerous folder locations for sources, for example an htdocs or www folder for web projects, and a different location for desktop Java applications.
The condition mentioned occurs when Eclipse is told to create a new project, and given a full folder outside the workspace. Eclipse will say the folder isn't empty, and prevent creating a new project within the given folder. I haven't found a way around this, and any solution requires extra steps.
My favorite solution is as follows
Rename the full folder with an appended "Original" or "Backup.
Create the Eclipse project with the name of the full folder before the folder was renamed.
Copy all the relabeled full folders contents into the new project folder.
Eclipse should make a new project, and update that project with the new folder contents as it scans for changes. The existing sources are now part of the new project.
Although you had to perform three extra steps, you now have a backup with the original sources available, and are also able to use a copy of them in an existing project. If storage space is a concern, simply move/cut the source rather than fully copy the original folder contents.
If you creating a new project based on an existing Maven structure :
Create the project using a general project wizard and give the project the same name as just created.
If you try to create the project as a Maven project via m2e will receive an error that project/pom already exists.
Create a new project..
Right Click on your project..
Select Build path --> Configure Build Path
Under source tab choose link source, your .java files containing folder..
I am suggesting this since none of the methods that you tried have worked ---FYI
Follow this instructions from standard eclipse docs.
From the main menu bar, select command link File > Import.... The Import wizard opens.
Select General > Existing Project into Workspace and click Next.
Choose either Select root directory or Select archive file and click the associated Browse to locate the directory or file containing the projects.
Under Projects select the project or projects which you would like to import.
Click Finish to start the import.
