What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?
latest check out for the source code of i-jetty 

Please provide any additional information below.

I have modified the parent pom and the i-jetty-ui pom to relfelct anndroid api 
level 20 which is the one which I got based on lastest android SDK.  Now as I 
can see the aapt.exe on window is located 
at ${ANDROID_HOME}/build-tools/20.0.0
I have not looked at the android maven plugin to see what path it looks for 


using the below plugin version :
<groupId>com.jayway.maven.plugins.android.generation2</groupId>
          <artifactId>maven-android-plugin</artifactId>
          <version>2.9.0-beta-5</version>

and from the  exception  during the debug level 

 at com.jayway.maven.plugins.android.AndroidSdk.getPathForTool(AndroidSdk.java:164)
        at com.jayway.maven.plugins.android.phase01generatesources.GenerateSourcesMojo.generateR(GenerateSourcesMojo.java:428)
        at com.jayway.maven.plugins.android.phase01generatesources.GenerateSourcesMojo.execute(GenerateSourcesMojo.java:141)
        at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:132)

and the source code for the plugin does not look into the following possible 
path 

${ANDROID_HOME}/build-tools/20.0.0 


Another issue is when using the latest maven android plugin  version
 3.9.0-rc.2 which is the latest; you will get an issue of duplicate file in the class-path from jetty server; the file called "about.html" and it is inserted as a remote resource jar file during the jetty server build
