* **Java source compatibility** is the ability to upgrade Java uses of OkHttp 3.x to 4.x without
   changing `.java` files.

 * **Kotlin source compatibility** is the ability to upgrade Kotlin uses of OkHttp 3.x to 4.x
   without changing `.kt` files.

With a few small exceptions (below), OkHttp 4.x is both binary- and Java source-compatible with

- JUnit 4 + Hamcrest matchers
- Test class: `{ClassName}Test.java`
- Test method: `test{MethodName}`

## Naming Conventions

| Type | Pattern |
|------|---------|
| Utility | `{Feature}Util.java` |
| Conversion | `{Type}ConversionUtil.java` |
| Exception | `{Name}RuntimeException.java` / `Cl{Name}Exception.java` |
| Implementation | `{Interface}Impl.java` |

## Important Notes

1. Always run `mvn test` after changes

# ...otherwise, source the specified include.
elif [ -r "$FESS_INCLUDE" ]; then
    . "$FESS_INCLUDE"
fi

if [ -x "$JAVA_HOME/bin/java" ]; then
    JAVA="$JAVA_HOME/bin/java"
else
    JAVA=`which java`
fi

if [ ! -x "$JAVA" ]; then
    echo "Could not find any executable java binary. Please install java in your PATH or set JAVA_HOME"
    exit 1
fi

if [ -z "$FESS_CLASSPATH" ]; then
