Eclipse git clone -> general project -> java project

Project Setup

File > Import
Git > Projects from Git
Clone URI
Enter info, icl. clone URL from GitHub. If it's in your clipboard most should already be entered.
Select branches, local repo directory, etc.
If eclipse project file is not present in repo: (likely and troublesome scenario)
    Import as general project
    Name > Finish

Now you have the project, linked with a local git repo and the remote repo (presumably on GitHub).
But it's a "General project," and cannot be compiled or run.

Conversion to Java project:
Go to project directory, open .project file in a text editor. It may be hidden.
Add some things:
````
<buildSpec>
+	<buildCommand>
+		<name>org.eclipse.jdt.core.javabuilder</name>
+		<arguments>
+		</arguments>
+	</buildCommand>
</buildSpec>
<natures>
+	<nature>org.eclipse.jdt.core.javanature</nature>
</natures>
````

So now it will build, but run any src folder is probably still borked and every package declaration is "wrong."
Fix:
(Right click on project "run as" or "Run" menu) > Run configurations
Set name, main class, etc. if not already.
Classpath Tab:
Click "User Entries"
Click Advanced
Add Folders
Select to your project's src folder, and any other source folders.
OK > Apply

One more snag might be compiler/JRE settings:
Right click project > Properties > Click "Java Compiler"
Note any warnings at the bottom, usually just set project to your highest version JRE and compiler compliance.
Note that if you are contributing to a project, they might want a certain compliance version.

Of course a project might also require libraries.
Right click project > Build Path
Add External Archives OR Configure Build Path > Add JARs if they are in workspace (included in project)

<<< Heavy WIP below >>>

If the project is a github fork, and you want to be able to pull from the original repo you forked from,
you're not done:

Window > Show View > Other > Git > Git Repositories
Right click project repo > Properties
Click remote > origin > url
Add Entry > key = "remote.origin.url" value = URL for original repo > OK
Right click project > Team > Remote > Configure Push to Upstream
URI field: "Change" > put in URL for your repo, and your user creds.

Now "Pull" should pull from both repos, the parent and your fork, but only push to the fork.
