jbonofre opened a new issue, #44:
URL: https://github.com/apache/karaf-minho/issues/44
With the `minho-spring-boot` application manager, the user can load several
spring-boot application via the `ConfigService#Applications`. For instance, he
can define spring-boot applications via `minho.json` file:
```json
{
"applications": [
{
"name": "one-app",
"type": "spring-boot",
"url": "file:./app/my-spring-boot-app-1.0-SNAPSHOT.jar",
"properties": {
"args": "--server.port=8181"
}
}
]
}
```
If the `minho-spring-boot` application manager doesn't find the jar on the
provided `url`, the user get this error:
```

```
It could be confusing as the problem is not really `ClassNotFoundException:
org.springframework.boot.loader.JarLauncher` but actually the application jar
file is not found.
The `minho-spring-boot` application manager should first check if the jar
exists on the provided URL and throw a clean message if not.
