Regarding eclipse libraries - eclipse

Have a question on eclipse libraries. I have an eclipse java project where I have created a library which contains some 50 odd jars files which are needed by the project. Now I have created a new project where I need the library. A very cumbersome way to do this is to check all the jar files in that library, them create a new library in my current project where I will manually add all the 50 odd jars. Is there a way I can export the library from my old project to the current project so that I can have all the requisite jars in one shot.
Regards,
Dev

Yup you can export the lib.
refer to the screen shot
Just select the Lib you want to export , then select export button
Enter the path where you want to store the export file
Now to import, go the the same place and select the import option
Select the import file and click ok

How to import ATG CRS module in eclipse and customize

I am new to ATG and i installed ATG CRS 11.2 using CIM and it is installed properly and i am able to access the site but i want to import the CRS module in eclipse and customize the existing code for my learning purpose.
I tried the ways given on net, install atg plugin and trying to import but it is not importing.
Please explain the steps to do same.
Thanks
The Oracle A-Team have an article Building Oracle ATG Commerce With Maven. They have created a sample github project which uses CRS 11.2 as the basis for the project. You should be able to import this as a Maven project within Eclipse.
Create a new Java Project in Eclipse
Using windows browser, go to the location where your Java Project is created.
Open the Java Project folder, you will find .classpath and .project files there.
Now, go to your ATG_ROOT folder, and find the folder CommerceReferenceStore/Store
Copy-paste your .project and .classpath files here.
Edit the .project file and replace the project name by CommerceReferenceStore.Store.
CRS also has some other (nested) modules. Do the same for the nested modules you want to import in eclipse.
Re-open eclipse, Go to File -> Import -> Other -> Existing Projects into your workspace.
Browse to your ATG_ROOT directory and select the Store folder
Check on "Search for Nested Projects"
It will populate a list of all the projects, which you can now import.
For customizing CRS, it is not recommended to modify the existing CRS
code. You can create a new module, and layer it on top of CRS to
customize it. For more details on creating a new module above CRS, and
doing an assemble-deploy via CIM, you can follow this article provided
below. It has 3 small parts which can get your task done!

Export maven project from eclipse

Is there a way to export an entire Maven project from eclipse? I don't just want a jar file, I'm looking for a way that another person can download the entire project with the dependencies and all that already set up the same way that I have it.
Just copy the project folder and make the other person import it as an "Existing Eclipse project". If you want to collaborate with that person on it, think of using Git or some other CMS to share it.
Maven will take care of getting the right dependencies.
If you export it as war file then you will not get back maven file. So it is better to just copy the project send it to other person, he/she just need to import as an exist project from path.

Getting imported files from sample java program to new program

I'm trying to make a small java program revolving around Google Calendars. I've never worked with java before but I was able to get Google's sample code working. In Eclipse, I simply used Import -> Maven, and then made some small changes to the code so that it worked on my Calendar.
Ok, great, now I want to write my own code. I started a new project and imported the Google Calendar API. At the very beginning, there are several import actions:
import com.google.api.client.auth.oauth2.Credential;
import com.google.api.client.extensions.java6.auth.oauth2.AuthorizationCodeInstalledApp;
import com.google.api.client.extensions.jetty.auth.oauth2.LocalServerReceiver;
import com.google.api.client.googleapis.auth.oauth2.GoogleAuthorizationCodeFlow;
.
.
.
It turns out that I'm missing the second and third files. How do I find these files and how to do import them to the new project?
Please note: I ultimately don't want to rely on importing the Google Calendar API or anything similar, as I will be using another non-java program to run and control this one.
Here's what I tried:
I go back to the sample code, expand Maven Dependencies and find:
google-oauth-client-jetty-1.19.0.jar
google-oauth-client-java6-1.19.0.jar
I see that these files are in:
C:\******\.m2\repository\com\google\oauth-client\google-oauth-client-jetty\1.19.0
C:\******\.m2\repository\com\google\oauth-client\google-oauth-client-java6\1.19.0
I tried to add these with Import -> Java EE -> App Client JAR file
Didn't work, do I need to change the file name or import name? Maybe these aren't the correct files anyway.
I also tried to add these by creating a lib folder in my project folder and add the JAR files directly there.
I guess from your question your project is just an Eclipse project rather than a Maven project. Obviously Maven automatically add the required jars of the dependencies stated in pom.xml for example google-oauth-client-java6-1.19.0.jar is a dependency of google-oauth-client-jetty-1.19.0.jar.
To add external jar to your project in Eclipse you need to select the project then from the Project menu select Properties. On the properties popup click on the Java Build Path, you have two options depending where the jars are stored, if you are referring to the maven .m2 directory then choose 'Add External Jars' otherwise if you added them to a lib folder in the project choose Add Jars

How to create a GWT Library jar from existing GWT Project?

I have a working GWT project library which I include to other GWT projects that need to use it. So far its been useful enough, however I need to make it a library jar, what is the process of doing it?
I tried to export the jar using File->Export->JAR File process with Eclipse however when I included the jar file in the same projects where I used to include the project file, it won't work.
Any ideas?
Make sure you package *.java along with *.class. Module gwt.xml should also be placed in correct package.
See an example here.
In eclipse export wizard, make sure "Export Java Source files and resources" checkbox is checked.

Import existing projects into Eclipse works only for projects that were created in Eclipse.
And you're definitely not dealing with an Archive File here.
Import from the File System just copies the resources but does not actually create an Eclipse project for you.
What I would advise you, is to create a new Dynamic Web Project, configuring all the required facets, and then just copy all the contents of your existing app to the WebContent folder, either by drag'n'dropping it into the Project Explorer or by using Import from the File System, overwriting all the contents.
So far, there seems to be no other way to do it in Eclipse. However you may check out the similar post. The user #RC recommends using ant task for this process, but I'm more than sure that it won't configure all the required facets for you. It may work for some simple Java projects, but surely not enough for Java EE projects.
