Oracle MAF : Deployment error when using cordova plugin

I have tried to integrate cordova plugin into Oracle MAF application for accessing different feature like Image Capture, Audio and Video.

For sample, I have tried with cordova-plugin-media-capture from Github. Following is the workaround, I have added downloaded plugin into Additional Plugins in MAF application.

Please note, I have plugin outside of the project since I got issue when having it inside the project. (You may get the details by checking edit history of this post).

Now when I try to deploy the app i'm getting INTERNAL_ERROR, below is the stacktrace for your reference.

Error Log:

I googled and got the link for this issue. Below are my try, But none of them works.

  • Shorten android sdk path, application path, plugin path.
  • All path without space.
  • Ran the JDeveloper as Administrator.

Please share your ideas, if you have any.

Solution

  • To resolve this issue, Keep the plugin outside of the project (Your local drive of the system) and refer in the maf-application.xml file using below steps.

    • Go to Application Resources block in JDeveloper.
    • Open maf-application.xml under Description -> ADF META-INF folder.
    • maf-application.xml file gets open, make sure you have select the Overview mode.
    • Then follow this tutorial (Registering Additional Plugins in Your MAF Application) for adding additional plugin (which you want to use).
    • Make sure you have unchecked unwanted Core-Plugins (Like Camera - when you add cordova media capture plugin). Since this lets to conflict MAF application, which one need to be used while building the deployment file.
    • You can open maf-plugin.xml file to confirm whether additional plugin have been added or not.

    That's it, deploy the application and check.
