### Gradle runtimes

Gradle is also made up of several different processes that work together to "run the build", such as the Gradle daemon and the `gradlew` command.

Each process, or "runtime", applies different constraints to the code that runs in that process.
For example, each process has different supported JVMs and a different set of services available for dependency injection.

#### JVM platform

This is a platform that builds on the core and software platforms to add support for developing software that runs on the JVM.
This includes software that is implemented using Java, Kotlin or some other JVM language.

This platform provides specific support for Java, Groovy and Scala, and includes the foojay toolchain plugin. 

#### Extensibility platform

- Some base services that are available to code hosted by the runtime. This varies by runtime.
- Additional constraints. For example, the CLI client runtimes limit the libraries that are available to the code in that runtime, for performance reasons. 

Other modules and platforms define the services that they contribute to the runtime.

labels.logout=Logout
# ... approximately 1,056 more entries
```

**`fess_message_[locale].properties`** contains system messages such as:
```properties
errors.required={0} is required.
errors.minlength={0} cannot be less than {1}.
success.login=Logged in successfully.
# ... approximately 200 more entries
```
