Unable to Create WebViewPlugin.Jar

[sandeepsmartest]

I made some changes, basically i just added a log as shown below

 @JavascriptInterface
    public void call(final String message) {
                 Log.d("its just a log CWebViewPlugin", cm.message());
        call("CallFromJS", message);
    }

I was unable to create jar file. Please check the below log while im trying to execute "install.sh"
