Eclipse buildpath automatically taking all JARs of a internal directory

Question

How do I configure my project buildpath to have a set of .jar files located in the same directory automatically included in the buildpath ? Meaning that adding a new .jar fi

Answer 1

I built a tool which generates the .classpath (and .project), but it requires you to specify the list of jars in your ant build. It could probably be extended to read a list of jar files.

On a windows machine you could do what uzhin said with a one liner on the command line.

Supposing you had set up a variable in Eclipse called AXIS2_HOME that points to c:\javalibs\axis2-1.4.1, this example uses the "for" command to iterate all of the .jar files in the c:\javalibs\axis\lib directory and writes the .classpath nodes a file called addto.classpath. (Note: The carat character ^ escapes the < and > on the command line so they don't do what they usually do.)

for %i in (c:\javalibs\axis2-1.4.1\lib\*.jar) do @echo     ^<classpathentry kind="var" path="AXIS2_HOME/lib/%~ni%~xi"/^>  >> addto.classpath

You end up with something like this in the file...

<classpathentry kind="var" path="AXIS2_HOME/lib/activation-1.1.jar"/>
<classpathentry kind="var" path="AXIS2_HOME/lib/annogen-0.1.0.jar"/>
<classpathentry kind="var" path="AXIS2_HOME/lib/axiom-api-1.2.7.jar"/>
<classpathentry kind="var" path="AXIS2_HOME/lib/axiom-dom-1.2.7.jar"/>
...

So then you can copy those lines and paste them in the obvious place in the actual .classpath file.

My colleague implemented a classpath container which recursivly looks for jars in a given directory within the workspace, have a look at http://openscada.org/2010/05/31/adding-a-directory-as-class-path-to-eclipse/

You can use a User Library in Eclipse can be a useful way to organize a set of jar files. If you have a set of jar files that you use in several projects, you can create a User Library to reference the set of jar files. As a result, all you would need to include in your project's build path is the User Library rather than all the individual jar files.

<classpathentry kind="con" path="org.eclipse.jdt.USER_LIBRARY/User Library name"/>
