ScalaInstance

```
public interface ScalaInstance
```
A Scala instance encapsulates all the information that is bound to a concrete Scala version, like the ClassLoader or all the JARs required for Scala compilation: library jar, compiler jar and others. Both a `ClassLoader` and the jars are required because the compiler's boot classpath requires the location of the library and compiler jar on the classpath to compile any Scala program and macros. NOTE: A "jar" can actually be any valid classpath entry.

All Methods Instance Methods Abstract Methods Default Methods Deprecated Methods
Modifier and Type	Method and Description
`java.lang.String`	`actualVersion()` The unique identifier for this Scala instance, usually obtained (but not necessarily) from `compiler.properties` files.
`java.io.File[]`	`allJars()` Classpath entries for the `loader`.
`default java.io.File`	`compilerJar()` Deprecated. Use `compilerJars` instead (since 1.5.0).
`java.io.File[]`	`compilerJars()` Classpath entry that stores the Scala compiler classes.
`default java.io.File`	`libraryJar()` Deprecated. Use `libraryJars` instead (since 1.3.0).
`java.io.File[]`	`libraryJars()` Classpath entries that stores the Scala library classes.
`java.lang.ClassLoader`	`loader()` A class loader providing access to the classes and resources in all the jars of this Scala instance.
`java.lang.ClassLoader`	`loaderCompilerOnly()` A class loader providing access to the classes and resources in the compiler jar of this Scala instance.
`java.lang.ClassLoader`	`loaderLibraryOnly()` A class loader providing access to the classes and resources in the library jars of this Scala instance.
`java.io.File[]`	`otherJars()` All the jars except `libraryJars` and `compilerJar`.
`java.lang.String`	`version()` Scala version for this `ScalaInstance`.

- Method Detail
  - version
```
java.lang.String version()
```
    Scala version for this ScalaInstance. It need not to be unique and can be dynamic (e.g. 2.10.0-SNAPSHOT).
  - loader
```
java.lang.ClassLoader loader()
```
    A class loader providing access to the classes and resources in all the jars of this Scala instance.
  - loaderCompilerOnly
```
java.lang.ClassLoader loaderCompilerOnly()
```
    A class loader providing access to the classes and resources in the compiler jar of this Scala instance. In Scala 2, `loaderCompilerOnly` and `loader` are not different. But in Scala 3, `loader` contains the `scala3doc` jar and all its dependencies, that are not contained in `loaderCompilerOnly`
  - loaderLibraryOnly
```
java.lang.ClassLoader loaderLibraryOnly()
```
    A class loader providing access to the classes and resources in the library jars of this Scala instance.
  - libraryJars
```
java.io.File[] libraryJars()
```
    Classpath entries that stores the Scala library classes.
  - libraryJar
```
@Deprecated
default java.io.File libraryJar()
```
    Deprecated. Use `libraryJars` instead (since 1.3.0).
  - compilerJars
```
java.io.File[] compilerJars()
```
    Classpath entry that stores the Scala compiler classes.
  - compilerJar
```
@Deprecated
default java.io.File compilerJar()
```
    Deprecated. Use `compilerJars` instead (since 1.5.0).
  - otherJars
```
java.io.File[] otherJars()
```
    All the jars except `libraryJars` and `compilerJar`.
  - allJars
```
java.io.File[] allJars()
```
    Classpath entries for the `loader`.
  - actualVersion
```
java.lang.String actualVersion()
```
    The unique identifier for this Scala instance, usually obtained (but not necessarily) from `compiler.properties` files.
