I have been trying for hours to import a library to Eclipse. I tried the simplest method that seems to be to copy the folders inside a lib folder inside the project in Eclipse.
Inside the project folder, the folder of the library is lib/org/imgscalr
I am using the code
import static org.imgscalr.*;
What am I doing wrong? I dont know if there is any difference, but I am using a MACBOOK.
I'd like to say that I used the " refresh" and I can see the folder and files there...
If your library is a jar file, then right click the project name and navigate to Build Path.
Select Configure Build Path, and there the Libraries tab. Then choose "Add JAR" or "Add external JAR"(see here and here). The difference between these options is that "Add JAR" is for jars in the project directory, while "Add external JAR" allows for JARs locates anywhere else.
If your "library" is in the form of a folder with classes, follow the steps above but choose "Add Class Folder" instead of "Add JAR".

I am new to Eclipse and Java, and I know that .jar files I need to add into libs derectory so that compiler could recognize them. How I can add .jars not only in libs folder but also in other folder too. How can I configure Eclipse to do that?
It's easiest if you have the jar files visible in the package explorer to start with, i.e. within your project directory. At that point, you can just right-click on the jar file, go to the "Build path" section of the context menu, then select "Add to build path".
If the jar file is elsewhere and you don't want to move it, you can right-click on the project, and under the "Build path" part of the context menu, select "Add external archives...". Then find the jar file in the file browser, and hit OK.
All of this can also be done from the project properties dialog, in the Java Build Path section.
Right Click project
Select Properties
Select Java Build Path
Under Tab Libraries Click on add jars or add external jar to add the required jars
The Java build path is used while compiling a Java project to discover dependent classes . It is made up of the following items:
Code in the source folders
Jars and classes folder associated with the project
Classes and libraries exported by projects referenced by this
project
Our goal is to feed our classes with the dependent classes present in the jars during compile time. Eclipse provies with number of easy ways to do it .Here you can find a good article about how to add the jars in the projects with screenshorts attached to it http://www.wikihow.com/Add-JARs-to-Project-Build-Paths-in-Eclipse-(Java)
I have a problem, I need to add a .jar file into android dependencies folder in eclipse. I have looked for similar stack posts but none of them worked for me.
I have tried pasting the jar file into the libs folder but it gives an error
cannot copy the clipboard content into the selected items"
I have to deliver my work by tomorrow. Please help. Thanks in advance
Add it to the classpath, which is specified by the "Java Build Path" menu in the project properties.
More info here: http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Freference%2Fref-properties-build-path.htm
If you're using the ADT plugin for Eclipse, you must add it to your classpath. Simply right-click on your project, choose 'Properties', go to the 'Java Build Path' tab, and, in the 'Libraries' tab, click "Add External JARs" and import your JAR. This will auto-import the file and allow you to use it in your projects.
Your problem may be similar to this one: Difference between Libraries & lib folders ? How do we add jar files to lib folder?
So I have imported by two .jar files into the libs folder using the following method:
Right click on libs > Import > Import File System and then bring them in.
Once they get brought in, right click libs > Build Path > Configure Build Path and add them to the Build Path of the project.
However, when I imported the package I needed to use in my project, it gave me the error "The import org.codehaus cannot be resolved."
Any idea how to fix this issue?
Place the jars in the libs folder of your project as you have done. Then, right click on the jar, go to Build Path -> Configure Build Path. In the Libraries tab click Add JARs... and select the library jar. Then, go to the Order and Export tab and make sure that the library jar is checked.
Here's some info I found on integrating Jackson libraries: http://supersabrams.com/blog/?p=81
You only need to put them in the libs folder.
Remove them from the build path as this will cause problems with libraries declaration.
I'm new to Java , and I would like to ask about importing libraries. I'm trying to import a folder, and I can import it from
properties ->
library ->
add jar/folder
I'm trying to add a folder that contain multiple jar files, but I can't find any sense in the "Add Folder" option, because I'm unable to use the classes that exist in that folder.
How do I add a folder and use all the classes or .jars it contains?

Here are the steps to creating Netbeans Library
Select Tools -> Ant Libraries
Select "New Library"
Provide new library name
Add Jars
Once you create library you can select that library in your projects.
You can create a "lib" folder under your project and contain all your jars there.
I am new to Eclipse IDE, I created a new project named "Hello World", and I need some APIs which are contained in a jar file.
I created a folder called "lib" under the project folder "Hello World" (parallel with src folder), and I import the .jar file into this lib folder, it extracts all the things to this lib folder automatically.
Then I created my HelloWorld.java class under src folder, however, when I put import ro.xxx.xxx.xxx, eclipse complains "the import ro cannot be resolved". Actually, the ro is under the lib folder.
I am stuck here. Shall I make this lib folder under the src folder instead of parallel with it? Please kindly give me some suggestions, thanks in advance!
Project -> properties -> Java build path -> libraries -> add external jars
Just Putting jar in lib folder won't work , you need those jars in your class path.
Here it is described how to add jars in to your build path in eclipse
Add the library to your build path.
Right mouse button on your project --> Build Path --> Configure Build Path...
Libraries --> Add jar
After you first create the lib folder parallel to the src folder you need to go back into Eclipse and Refresh the project so that Eclipse finds the new folder and jars. You can either highlight the project and hit F5, or use the right click menu off the project. After that the lib folder and jar files appear and you can right click a jar to add to the build path. If you add new jars subsequently you need to refresh again for Eclipse to find them.
