### Events with Failures

When an operation fails, a failure method is called. This is `connectFailed()` for failures while building a connection to the server, and `callFailed()` when the HTTP call fails permanently. When a failure happens it is possible that a `start` event won’t have a corresponding `end` event.

 5. It sends the HTTP request and reads the response.

It looks like the following:

```
Execution failed for task ':architecture-test:checkBinaryCompatibility'.
> A failure occurred while executing me.champeau.gradle.japicmp.JApiCmpWorkAction
   > Detected binary changes.
         - current: ...
         - baseline: ...
     
     See failure report at file:///<path to Gradle checkout>/subprojects/architecture-test/build/reports/binary-compatibility/report.html
