BndTools, How to add a non-OSGi JAR? I wanted to add jcraft Libraries into my osgi project. Using plain JAR breaks the whole project. Missing requirement wiring package

ERROR: Bundle com.herle.iiot.application.installation [6] Error starting file:/D:/HERLE/Data/iot-sdk/FelixLauncher/bundle/com.herle.iiot.application.installation-1.5.0.jar

e, felix.fileinstall.tmpdir = .\tmp, felix.fileinstall.filter = null, felix.fileinstall.start.level = 0}

Please let me know how can one do this using bnd.bnd config file?

回答1:

Main thing to consider is configuration. If you are using external library or jar then you need to mention it as private package.

please find my sample bnd.bnd file.

Bundle-Name: ${project.artifactId}
Bundle-SymbolicName: ${project.artifactId}
Bundle-Description: Template-Bundle for developing an application
Bundle-Category: Application
Bundle-Copyright: 2017 (c) [e-mail]
-dsannotations: *
-metatypeannotations: *
Private-Package: \
    com.jcraft,\
    com.jcraft.jsch,\
    com.jcraft.jsch.jce,\
    com.jcraft.jsch.jcraft,\
    com.jcraft.jsch.jgss,\
    com.jcraft.jzlib

I suggest you to use BndTools to edit the bnd.bnd file. you can install BndTools plugin to eclipse from BndTool Installation.

Select the packages that you need.

Note: Since it automatically does not install all the dependencies you need to add if any extra jars required. i.e I wanted to use jsch, which had a dependency on jzlib. So I added these two entries in pom.xml file.

<dependency>
    <groupId>com.jcraft</groupId>
    <artifactId>jsch</artifactId>
    <version>0.1.54</version>
</dependency>


<dependency>
<groupId>com.jcraft</groupId>
<artifactId>jzlib</artifactId>
<version>1.1.3</version>
</dependency>

Hope this helps some! Please vote so that i can write more solution.
