Unable to compile Face Recognition example

Hello all,

I followed the instructions provided for running the face recognition example. However, I am unable to build the project and getting following error:

# ./gradlew build

/home/face-recognition-demo/src/main/java/facerecog/Recognition.java:13: error: type SapphireObject does not take parameters

Any idea what's going wrong. Thanks, Obaid

Thanks @obaidamin for the bug report. And congratulations for being the first non team member to report an issue! :-)

It looks like that example code is slightly out of date w.r.t. the Sapphire core. We'll have to fix that tomorrow.

In summary what needs to be done is remove the parameter from SapphireObject, which specifies the DeploymentManager associated with the SapphireObject. That has been replaced by a yaml config file.

If you're feeling brave, take a look at:

https://github.com/Huawei-PaaS/DCAP-Sapphire/blob/master/sapphire/examples/kvstore/src/main/java/sapphire/demo/KeyValueStore.java#L13

and

https://github.com/Huawei-PaaS/DCAP-Sapphire/blob/master/sapphire/examples/kvstore/src/main/resources/KeyValueStore.yaml

and feel free to send a PR to fix this.

PS: I can also add you to our slack channel, so that you can get more realtime responses from the team.

Actually I see #23 already addresses this problem. It just needs to be merged. We will try to do that tomorrow.

Please sync and try again @obaidamin

I'm going to close issue for now. Feel free to re-open if you're still unable to build or run the example.

@obaidamin @quinton-hoole-2 : #23 indeed takes care of this. @obaidamin where you able to build the docker image? It turns out the link to jdk1.8.0_181-b13 on line 78 of the Dockerfile is outdated. Oracle has archived that version and the link now redirects to a login page. You may want to update that line to point to http://download.oracle.com/otn-pub/java/jdk/8u191-b12/2787e4a523244c269598db4e85c51e0c/jdk-8u191-linux-x64.tar.gz

Thanks @quinton-hoole the problem is fixed.

@neerajkc: Yes I had to change Docker file for that. It was a minor change so didn't bother you guys :).
