extender-frontend:
```
extender:
cache:
enabled: true
type: LOCAL
local:
basedir: "/extender/cache/data"
file-size-threshold: 65536
```

extender-macos:
```
cache:
enabled: true
type: LOCAL
local:
basedir: "/extender/cache/data"
file-size-threshold: 65536

```

### steps to reproduce:
1. enable cache
2. build ios app
3. stop macos extender
4. rm -rf /extender/cache/data/*
5. start macos extender
6. run build again
7. got error

No source file or test is named. Start by reproducing the Java extender cache sequence: enable LOCAL caching, build, delete /extender/cache/data/*, restart the macOS extender, and build again. Done means the subsequent build succeeds instead of reporting that the cached object was not found.
