Issue with Microsoft Graph java Sdk and proguard for Android release

Question

I use msgraph-sdk-java in my Android application mainly to access OneDrive. In debug mode everything is ok but when I compile in release mode with minify enabled, i have an issue.

mGraphServiceClient.me().drive().root().children().buildRequest();

DefaultHttpProvider[sendRequestInternal] - 370Error during http request Throwable detail: com.microsoft.graph.core.ClientException: Error during http request..

and

com.microsoft.graph.core.ClientException: Error during http requ at com.microsoft.graph.http.DefaultHttpProvider.sendRequestInternal(:368) at com.microsoft.graph.http.DefaultHttpProvider.access$000(:53) at com.microsoft.graph.http.DefaultHttpProvider$1.run(:155) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1162) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:636) at java.lang.Thread.run(Thread.java:764) Caused by: java.lang.RuntimeException: java.lang.ClassNotFoundException: com.sun.ws.rs.ext.RuntimeDelegateImpl at javax.ws.rs.ext.RuntimeDelegate.findDelegate(:122) at javax.ws.rs.ext.RuntimeDelegate.getInstance(:91) at javax.ws.rs.core.UriBuilder.newInstance(:69) at javax.ws.rs.core.UriBuilder.fromUri(:80) at com.microsoft.graph.http.BaseRequest.getRequestUrl(:147) at com.microsoft.graph.http.DefaultHttpProvider.sendRequestInternal(:239)

Here is the return of gradlew myapp:dependencies where the javax.ws.rs appears.

+--- com.microsoft.graph:microsoft-graph:1.4.+ -> 1.4.0
    |    +--- org.apache.commons:commons-math3:3.6.1
    |    +--- com.google.code.gson:gson:2.8.2

    |              \--- javax.ws.rs:jsr311-api:1.1.1// <----here?

Here is what I tried in my proguard-rules.pro file:

-keep class com.microsoft.** { *; }
-keep class com.microsoft.**
-keep interface com.microsoft.** { *; }
-keepclasseswithmembernames class com.microsoft.** { *; }

-keep class com.sun.ws.** { *; }
-keep class com.sun.ws.**
-keep interface com.sun.ws.** { *; }

-keep class com.sun.jersey.** { *; }
-keep class com.sun.jersey.**
-keep interface com.sun.jersey.** { *; }

my build.gradle where i must exclude META-INF/jersey-module-version' because this file is present in com.sun.jersey:jersey-server:1.19.4 and com.sun.jersey:jersey-core:1.19.4:

I have tried many things but I have no ideas. Thanks for your help.

This fixed the issue for me :

implementation('com.microsoft.graph:microsoft-graph:1.6.0'){
    exclude group: 'com.sun.jersey', module: 'jersey-core'
    exclude group: 'com.sun.jersey', module: 'jersey-server'
}

implementation(group: 'com.sun.jersey', name: 'jersey-bundle', version: '1.19.4'){
    exclude group: 'javax.ws.rs', module: 'jsr311-api'
}

Also make sure to make the respective pro-gaurd entries to retain com.sun.* classes.
