如何使用jar库刷新Eclipse RCP插件

Question

I have one Eclipse RCP plugin (A) that include another one with jar libraries (B) and it works but i want to add there another jar library and i cant refresh my Eclipse RCP Plugin (A) to make packages from new jar visible.

I added new jar in MANIFEST.MF and Properties->Java build Path->Libraries as i had added a lot of others jar libraries.

Should i refresh project somehow to make it visible?

I use Eclipse for RCP and RAP Developers

Version: Mars.1 Release (4.5.1) Build id: 20150924-1200

(btw is it the only way to include external jar libraries? is it good way to do it or does anyone has better solution?)

EDIT: The problem is resolved. I had to Launch (and build?) my Eclipse RCP Plugin with jar libraries (i thought that it doesnt have to be compiled but it is a config that just exist to describe libraries that are included).

Answer 1

In your plugin containing the jars you must list all the packages that other plugins can see in the 'Exported Packages' section on the 'Runtime' tab of the MANIFEST.MF editor. You must also list the jars in the 'Classpath' section.

The jars should be in the plugin and must also be listed in the 'build.properties' so that they are included in the RCP build. You should not have to set anything in the Java Build Path.

Here is an example of how the 'Runtime' tab should look:

Here I have 4 jars in a 'lib' directory with lots of exported packages.
