Hi,
I was trying to use the Thingworx java sdk with docker to build an image out of it and use it as a docker container. I followed the following steps:
1) I loaded the application into eclipse
2) I ran gradel build gradle Build from eclipse which exported the app as a jar
3) I built an image using "docker build -t imagename ." in the directory of the jar
4) docker run imagename
This throws an error saying mainclass not found
I tried running the jar exported using java -jar filename.jar That throws the same error. Below is my build.gradle file
/*
Install gradle at https://gradle.org/ and execute 'gradle run' or 'gradle SimpleClient'
in this directory to run an example. Other examples can be run
with the commands 'gradle SimpleThing' and 'gradle Steam'.
You can also generate an Eclipse project with the command 'gradle eclipse' or
install the gradle eclipse plugin from the Eclipse Marketplace and Import it into eclipse.
*/
apply plugin: 'java'
apply plugin: 'application'
//apply plugin: 'docker'
apply plugin: 'eclipse'

version = '1.0'
mainClassName = "com.thingworx.sdk.simplething.SimpleThingClient"
// Customize the settings below to run the SteamClient

main = "com.thingworx.sdk.steam.SteamSensorClient"
args project.ext.serverUrl,project.ext.appKey,project.ext.scanRate,project.ext.startSensor,project.ext.numberOfSensors
}
Below is the error message (This is the only line that prints)
"Error: Could not find or load main class com.thingworx.sdk.simplething.SimpleThingClient.class"
using same process other apps that I worked on previously not involving Thingworx does not throw this issue
