Hi,
If using a Gradle as Build tool give dependencies in build.gradle file
No need of specifying in bnd.bnd file
it should only consists this

Ravi is totally wrong here, don't listen to him.
Your issue is your Bundle-ClassPath declaration. This declaration spells out what the class path should be.
You have some formatting errors here.
1. The backslash means "include next line". On line 12 you have it, but line 13 is empty. Line 14 is ignored because it is not included in anything and also not in the proper key: value format. You repeat this error on line 18.
2. You should not be pulling in portal-service and kernel.jars, there is no reason to do this, they are in the OSGi runtime already so your inclusion of them will have negative impacts on your runtime.
3. Same is true for your -includeresource declaration, you don't have to include most of these (except for jazzy) because they are in OSGi already.
Take a look at my blog post for the proper way to handle OSGi dependencies: https://web.liferay.com/web/user.26526/blog/-/blogs/osgi-module-dependencies

Thanks David.. I read your blog and came to know about some good points. Now I moved ahead a little bit and got rid of those errors. But I got another problem. I got the status as installed rather than active and it is due to -Unresolved requirement: Import-Package:com.liferay.mail.model . I found that it's present inside portal-service.jar. Should I include the dependency for portal-service.jar in the build.gradle file? If no, then what should I do to get rid of this error? Please help... thanks in advance..The modified bnd.bnd file is as follows:-
Bundle-SymbolicName: test.module1
Bundle-Version: 1.0.0
Import-Package: com.liferay.mail.model.*
Bundle-ClassPath:\
.,\
lib/knowledge.jar,\
lib/jazzy.jar,\
lib/util.jar,\
lib/bnd.jar
-includeresource:\
lib/knowledge.jar=com.liferay.knowledge.base.api-1.0.1.jar,\
lib/util.jar=util-java-6.2.4.jar,\
lib/bnd.jar=bnd-2.4.0.jar,\

Where did you refer the Bundle-ClassPath: lists
And -includeresource:\lists
Can you please where do you refer. I'm using Liferay 7, is it the same for liferay 7 also???
