## Create a provs jar-file
|
|
|
|
* Clone this repo
|
|
* Build the jar-file by `./gradlew uberjarDesktop`
|
|
* In folder build/libs you'll find the file `provs-desktop.jar`
|
|
|
|
This uberjar is a Java jar-file including all required dependencies.
|
|
|
|
## Task
|
|
|
|
```kotlin
|
|
fun Prov.provisionK8s() = task { /* ... code and subtasks come here ... */ }
|
|
```
|
|
|
|
If you're having a deeper look into the provs code, you'll see regularly a task definition like this and might wonder ...
|
|
|
|
### What is a task ?
|
|
|
|
A task is the **basic execution unit** in provs. When executed, each task produces exactly one result (line) with either success or failure.
|
|
|
|
The success or failure is computed automatically in the following way:
|
|
* a **task** fails if it calls subtasks and if at least one subtask has failed
|
|
* a **taskWithResult** works the same except that it requires an additional result to be returned which is also included in the success calculation
|
|
* a task defined with **optional** (i.e. `= optional { /* ... */ }` always returns success (even if there are failing subtasks)
|
|
* **requireLast** defines a task which must provide an explicit result and solely this result counts for success calculation
