How do I import a jar in Eclipse?

You can add a jar in Eclipse by right-clicking on the Project → Build Path → Configure Build Path. Under Libraries tab, click Add Jars or Add External JARs and give the Jar. A quick demo here.
The above solution is obviously a "Quick" one. However, if you are working on a project where you need to commit files to the source control repository, I would recommend adding Jar files to a dedicated library folder within your source control repository and referencing few or all of them as mentioned above.

Adding external Jar is not smart in case you want to change the project location in filesystem.
The best way is to add the jar to build path so your project will compile if exported:
Create a folder called lib in your project folder.
copy to this folder all the jar files you need.
Refresh your project in eclipse.
Select all the jar files, then right click on one of them and select Build Path -> Add to Build Path

Two choices:
1/ From the project:
2/ If you have already other jar imported, from the directory "References Libraries":
Both will lead you to this screen where you can mange your libraries:

Here are the steps:
click File > Import. The Import window opens.
Under Select an import source, click J2EE > App Client JAR file.
Click Next.
In the Application Client file field, enter the location and name of the application client JAR file that you want to import. You can click the Browse button to select the JAR file from the file system.
In the Application Client project field, type a new project name or select an application client project from the drop-down list. If you type a new name in this field, the application client project will be created based on the version of the application client JAR file, and it will use the default location.
In the Target runtime drop-down list, select the application server that you want to target for your development. This selection affects the run time settings by modifying the class path entries for the project.
If you want to add the new module to an enterprise application project, select the Add project to an EAR check box and then select an existing enterprise application project from the list or create a new one by clicking New.
Note: If you type a new enterprise application project name, the enterprise application project will be created in the default location with the lowest compatible J2EE version based on the version of the project being created. If you want to specify a different version or a different location for the enterprise application, you must use the New Enterprise Application Project wizard.
Click Finish to import the application client JAR file.

Just a comment on importing jars into Eclipse (plug-in development) projects:
In case you are developing Eclipse plug-ins, it makes sense to use Eclipse's native bundling mechanism instead of just importing the jar into a plug-in project. Eclipse (or better its underlying OSGi runtime, Equinox) uses so-called bundles which contain some more information than plain jars (e.g., version infos, dependencies to other bundles, exported packages; see the MANIFEST.MF file). Because of this information, OSGi bundles can be dynamically loaded/unloaded and there is automatic dependency resolution available in an OSGi/Eclipse runtime. Hence, using OSGi bundles instead of plain jars (contained inside another OSGi bundle) has some advantages.
(BTW: Eclipse plug-ins are the same thing as OSGi bundles.)
There is a good chance that somebody already bundled a certain (3rd party) library as an OSGi bundle. You might want to take a look at the following bundle repositories:
http://www.springsource.com/repository/app/
http://download.eclipse.org/tools/orbit/downloads/
http://www.osgi.org/Repository/HomePage

Eclipse -> Preferences -> Java -> Build Path -> User Libraries -> New(Name it) -> Add external Jars
(I recommend dragging your new libraries into the eclipse folder before any of these steps to keep everything together, that way if you reinstall Eclipse or your OS you won't have to rwlink anything except the JDK) Now select the jar files you want. Click OK.
Right click on your project and choose Build Path -> Add Library
FYI just code and then right click and Source->Organize Imports

Jar File in the system path is:
C:\oraclexe\app\oracle\product\10.2.0\server\jdbc\lib\ojdbc14.jar
ojdbc14.jar(it's jar file)
To import jar file in your Eclipse IDE, follow the steps given below.
Right-click on your project
Select Build Path
Click on Configure Build Path
Click on Libraries, select Modulepath and select Add External JARs
Select the jar file from the required folder
Click and Apply and Ok

first of all you will go to your project what you are created
and next right click in your mouse and select properties in the bottom
and select build in path in the left corner and add external jar file add click apply .that's it

In eclipse I included a compressed jar file i.e. zip file. Eclipse allowed me to add this zip file as an external jar but when I tried to access the classes in the jar they weren't showing up.
After a lot of trial and error I found that using a zip format doesn't work. When I added a jar file then it worked for me.

Right Click on the Project.
Click on Build Path.
Click On Configure Build Path.
Under Libraries, Click on Add Jar or Add External Jar.

If you are having a trouble on udemy course of chad on springboot for the importing the jar. Then follow these steps.
Right click on the project.
You will see a option of Build Path, click on it.
You will have a option of Configure Build path, click on it.
Go to libraries.
Then go to the place where you have a jar files make them into a new folder and upload on a new place.
Then click on Add External Jars, you will surely be able to upload it which will help on classpathxmlapplicationcontext as well.
Thank you.

Add .jar to Buildpath but not Classpath within Eclipse

In this specific case I am creating a Minecraft mod (yea... I know) and to do what I need I am trying to add an external jar (ComputerCraft Mod) to the buildpath, but not have it to the classpath, because Forge (The mod loader) errors on duplicated mods (classes/jars). I believe this is caused by Eclipse automatically adding all the Buildpath classes to the classpath. If there is a setting that I somehow overlooked, or an option for the jar entry, that would be great. Thank you for any info/answers/documentation you are able to provide. Thanks!

Right click your project in eclipse -> Build Path -> Configure Build Path -> In popup window Click "Add External Jar" -> select the jar you want in build path from your machine.
But simply it can stated as
The classpath is used to find classes when executing a Java program.
The build path is used when Eclipse is compiling a Java program.

Where to put Java libraries?

I'd like to know how I can add Java libraries to an Eclipse project on a development machine so that they can be added to an Eclipse project without causing errors when someone who has the library in a different location. For example, one developer might add an external JAR in C:\Java, but another might have the same JAR somewhere else. (Where's C:\Java on Mac OS?) I thought I might set the CLASSPATH environment variable, but I can't figure how to add an external JAR from the CLASSPATH environment variable. I'd like to do this so that it works with any workspace. Is this possible?
This is specifically for use with Anypoint Studio, but I think the same problem would exist with any Eclipse-based IDE.

In general, it's recommended to either embed JARs directly into the project, usually in a /lib folder of the project, as described here; or to use a tool like Gradle or Maven to manage dependencies, both of which have nice plugins to support their use in Eclipse.
Another alternative would be to use a Classpath Variable to refer to the JAR(s), which abstracts the physical location so that it can be set on a per-workspace basis.

I think the best way to add library to eclipse project is creating a directory - lib in your project directory. Then add the whole lib to you eclipse class path. You can follow these step to add a lib to class path -
Right click on project and select properties
Select Java Build Path
click Add Library and create User Library
Now add External Jars to this library create at step 3.
By this a .classpath file is crated in you project directory and the CLASSPATH problem will be resolved

I guess the best way to do that would be using Maven, or a similar build system that can construct your Classpath base on dependencies.
You can add the dependencies to your pom and having the jars in your local maven repository in the machine.
http://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html
Because in any other approach you will need to maintain everything manually, and when having different OS the path will change.

Eclipse is just the IDE that will help to write code and assemble the project (JAR, WAR, ... ). You can add your external jars from wherever you want, and when you want to export your project (with eclipse) you may choose to package the required libraries into the jar.
However, I recommend always to use maven (or something like ) to avoid this kind of problems.

Part1:(import .jar file as library in Eclipse)
You make a new project to Eclipse(name:Project1)
When you open it you see JRE System Library[java version something]
1.right click on JRE System Library
2.Go->Build Path->Configure Build Path
3.You can see (Up right Corner the button[add jars or add external jars]
*Here i advise you to choose the first(add jars) but..
*First copy(or move) the (name).jar inside the project((example):Project 1)
*Now you can add it with the button(add jars).
*In this way when you finish your project the (name).jar will be
imported inside the project(If you export it as a .jar from Eclipse)
..Now you can call any method of (name).jar just(import it into the class
you want to use and call it)

How to package dependencies into java project with eclipse

I get this error when I try to run my project.
java.lang.NoClassDefFoundError: org/yaml/snakeyaml/Yaml
I am trying to include the dependency SnakeYaml.jar in my project so my project is only one jar instead of requiring an external dependency.
in my project SnakeYaml.jar is located at /Libs/SnakeYaml.jar
but it is not being loaded at runtime, what can I do to get it to load the resource at runtime?

The best solution to avoid such problems is creating maven based project by eclipse. when you export your project as jar or war files it puts all dependencies in the jar or war files

In Eclipse, to put the dependency packaged inside your project executable jar you can do this:
I cannot post images due to my reputation so will try to explaing it writting.
Make sure the dependency is in your class path: right click the project -> Build Path
Right click your project again and select "Export"
Now choose "Runnable JAR file" (you can filter the list by typing)
In the next dialog choose the right option for you, in your case it could be "Package required libraries into generated JAR"
Hope it helps

After building the project from pom.xml using Maven, how do I use its resources

It's been tedious. This is the API I am trying to use. Its resources were set up in a pom.xml which I built using Maven. On built up, it gave me the project socrata-publisher that has
src/main/java the source folder with packages com.socrata.api com.socrata.data, com.socrata.util where each contains only .java
files
JRE System Library and Maven Dependency hierarchies where each contains a number of jar files
Problem is com.socrata.api and the 2 other contains classes which I want to deploy in a project outside socrata-publisher. I tried using import com.socrata.api but it didn't work. Moreover, since its a Java project and not android it doesn't have the is Library option in preferences which could rather give me the solution. Both socrata-publisher and tutorial (where i want to use the resources and which is the android application) lie in the same directory eclipseApps in My Documents.
Here's a little visual queue. Help will be greatly appreciated.

You will need to first of all get the output of the socrata project and all its dependencies.
In command line, going to the project folder of the socrata project, where the pom.xml file is, run MVN INSTALL. You shall see a jar file called socrata-api.jar in $HOME/.m2/repository. If you are using windows and installed MAVEN by default, $HOME should be your user profile folder. Once you see the jar file, add it to your tutorial build path.

I think what you actually want to do is just set up the "socrata-publisher" as a project dependency for your "tutorial" project. That will allow you to reference the built Socrata libraries from the code in your project.
Right click on the project and select "Properties". From within that dialog select "Java Build Path" on the left, then the "Projects" section, and click the "Add" button to add the "socrata-publisher" project.
I think that'll work better than creating a separate jar file that you then include, and then you can also keep the socrata-publisher code up to date using Git.
