Update readme and test matrix

Introduce the dependency caching for Maven and Gradle (#193 )
* implement a core logic to cache dependnecies * integrate the cache logic to entry points * add a user doc about the dependency cache feature * reflect changes to the dist dir * add a prefix to the cache key https://github.com/actions/setup-java/pull/193/files#r669521434 * test: extract build.gradle to a file in __tests__ dir * run the restore e2e test on the specified OS * add an e2e test for maven * fix the dependency among workflows * stabilize the cache on the Windows in e2e test * add .gitignore files to __tests__/cache directories * try to run restore after the authentication * use the key in state to save caches in the post process * suggest users to run without daemon if fail to save Gradle cache on Windows * add missing description in the README.md * run clean-up tasks in serial * Add validation for post step (#3) * work on fixing cache post step * fix tests * Update src/cleanup-java.ts Co-authored-by: Konrad Pabjan <konradpabjan@github.com> * Update src/cache.ts Co-authored-by: Konrad Pabjan <konradpabjan@github.com> * style: put the name of input to the constants.ts * format: run `npm run build` to reflect changes to the dist dir * chore: update licensed files by `licensed cache` it still has three errors as follows: >* setup-java.npm.sax > filename: /Users/kengo/GitHub/setup-java/.licenses/npm/sax.dep.yml > - license needs review: other > >* setup-java.npm.tslib-1.14.1 > filename: /Users/kengo/GitHub/setup-java/.licenses/npm/tslib-1.14.1.dep.yml > - license needs review: 0bsd > >* setup-java.npm.tslib-2.3.0 > filename: /Users/kengo/GitHub/setup-java/.licenses/npm/tslib-2.3.0.dep.yml > - license needs review: 0bsd * fix: rerun ncc on macOS with node v12 * build: follow the suggestion at PR page https://github.com/actions/setup-java/pull/193#issuecomment-901839546 * fix: throw error in case of no package manager file found Co-authored-by: Dmitry Shibanov <dmitry-shibanov@github.com> Co-authored-by: Konrad Pabjan <konradpabjan@github.com>

+### Checkin
+
+- Do checkin source (src)
+- Do checkin a single index.js file after running `ncc`
+- Do not checking node_modules
+
+### NCC
+
+In order to avoid uploading `node_modules` to the repository, we use [zeit/ncc](https://github.com/zeit/ncc) to create multiple `index.js` files that gets saved under `dist/`.
+There are two main files that get created
+- `dist/setup/index.js`
+   - Core `setup-java` logic that downloads and installs an appropriate version of Java 
+   - Handling creating a `settings.xml` file to make it easier to publish packages
+- `dist/cleanup/index/js`
+   -  Extra cleanup script that is used to remove GPG keys (needed for certain self-hosted runner scenarios)
+
+If you're developing locally, after doing `npm install`, you can use the following commands
+```yaml
+npm run build # runs tsc along with ncc
+npm run format # runs prettier --write
+npm run format-check # runs prettier --check
+npm run test # runs jest
+npm run release # add all the necessary ncc files under dist/* to the git staging area
+```
+
+Any files generated using `tsc` will be added to `lib/*`, however those files also are not uploaded to the repository and are excluded using `.gitignore`.
+
+### Testing
+
+Tests are included under `_tests_/*` and can be run using `npm run-script test`.
+
+We ask that you include a link to a successful run that utilizes the changes you are working on. For example, if your changes are in the branch `newAwesomeFeature`, then show an example run that uses `setup-python@newAwesomeFeature` or `my-fork@newAwesomeFeature`. This will help speed up testing and help us confirm that there are no breaking changes or bugs.
+
+### Licensed
+
+This repository uses a tool called [Licensed](https://github.com/github/licensed) to verify third party dependencies. You may need to locally install licensed and run `licensed cache` to update the dependency cache if you install or update a production dependency. If licensed cache is unable to determine the dependency, you may need to modify the cache file yourself to put the correct license. You should still verify the dependency, licensed is a tool to help, but is not a substitute for human review of dependencies.

-This action sets up a java environment for use in actions by:
+This action provides the following functionality for GitHub Actions runners:
+- Downloading and setting up a requested version of Java. See [Usage](#Usage) for a list of supported distributions
+- Extracting and caching custom version of Java from a local file
+- Configuring runner for publishing using Apache Maven
+- Configuring runner for publishing using Gradle
+- Configuring runner for using GPG private key
+- Registering problem matchers for error output
+- Caching dependencies managed by Apache Maven
+- Caching dependencies managed by Gradle

- optionally downloading and caching a version of java by version and adding to PATH. Downloads from [Azul's Zulu distribution](http://static.azul.com/zulu/bin/).
- registering problem matchers for error output
+## V2 vs V1
+- V2 supports custom distributions and provides support for Zulu OpenJDK, Eclipse Temurin and Adopt OpenJDK  out of the box. V1 supports only Zulu OpenJDK
+- V2 requires you to specify distribution along with the version. V1 defaults to Zulu OpenJDK, only version input is required. Follow [the migration guide](docs/switching-to-v2.md) to switch from V1 to V2

-# Usage
+## Usage
+Inputs `java-version` and `distribution` are mandatory. See [Supported distributions](#supported-distributions) section for a list of available options.

-See [action.yml](action.yml)
-
-Basic:
+### Basic
+**Eclipse Temurin**
 ```yaml
 steps:
- uses: actions/checkout@latest
- uses: actions/setup-java@v1
+- uses: actions/checkout@v2
+- uses: actions/setup-java@v2
  with:
-    java-version: '9.0.4' // The JDK version to make available on the path. Takes a whole or semver Jdk version, or 1.x syntax (e.g. 1.8 => Jdk 8.x)
-    architecture: x64 // (x64 or x86) - defaults to x64
+    distribution: 'temurin' # See 'Supported distributions' for available options
+    java-version: '11'
 - run: java -cp java HelloWorldApp
 ```

-From local file:
+**Zulu OpenJDK**
 ```yaml
 steps:
- uses: actions/checkout@master
- uses: actions/setup-java@v1
+- uses: actions/checkout@v2
+- uses: actions/setup-java@v2
  with:
-    java-version: '4.0.0'
-    architecture: x64
-    jdkFile: <path to jdkFile> // Optional - jdkFile to install java from. Useful for versions not supported by Azul
+    distribution: 'zulu' # See 'Supported distributions' for available options
+    java-version: '11'
 - run: java -cp java HelloWorldApp
 ```

-Matrix Testing:
+#### Supported version syntax
+The `java-version` input supports an exact version or a version range using [SemVer](https://semver.org/) notation:
+- major versions: `8`, `11`, `16`
+- more specific versions: `11.0`, `11.0.4`, `8.0.232`, `8.0.282+8`
+- early access (EA) versions: `15-ea`, `15.0.0-ea`, `15.0.0-ea.2`, `15.0.0+2-ea`
+
+#### Supported distributions
+Currently, the following distributions are supported:
+| Keyword | Distribution | Official site | License
+|-|-|-|-|
+| `temurin` | Eclipse Temurin | [Link](https://adoptium.net/) | [Link](https://adoptium.net/about.html)
+| `zulu` | Zulu OpenJDK | [Link](https://www.azul.com/downloads/zulu-community/?package=jdk) | [Link](https://www.azul.com/products/zulu-and-zulu-enterprise/zulu-terms-of-use/) |
+| `adopt` or `adopt-hotspot` | Adopt OpenJDK Hotspot | [Link](https://adoptopenjdk.net/) | [Link](https://adoptopenjdk.net/about.html) |
+| `adopt-openj9` | Adopt OpenJDK OpenJ9 | [Link](https://adoptopenjdk.net/) | [Link](https://adoptopenjdk.net/about.html)
+
+**NOTE:** The different distributors can provide discrepant list of available versions / supported configurations. Please refer to the official documentation to see the list of supported versions.
+
+**NOTE:** Adopt OpenJDK got moved to Eclipse Temurin and won't be updated anymore. It is highly recommended to migrate workflows from `adopt` to `temurin` to keep receiving software and security updates. See more details in the [Good-bye AdoptOpenJDK post](https://blog.adoptopenjdk.net/2021/08/goodbye-adoptopenjdk-hello-adoptium/).
+
+### Caching packages dependencies
+The action has a built-in functionality for caching and restoring dependencies. It uses [actions/cache](https://github.com/actions/cache) under hood for caching dependencies but requires less configuration settings. Supported package managers are gradle and maven. The cache input is optional, and caching is turned off by default.
+
+#### Caching gradle dependencies
+```yaml
+steps:
+- uses: actions/checkout@v2
+- uses: actions/setup-java@v2
+  with:
+    distribution: 'temurin'
+    java-version: '11'
+    cache: 'gradle'
+- run: ./gradlew build
+```
+
+#### Caching maven dependencies
+```yaml
+steps:
+- uses: actions/checkout@v2
+- uses: actions/setup-java@v2
+  with:
+    distribution: 'temurin'
+    java-version: '11'
+    cache: 'maven'
+- name: Build with Maven
+  run: mvn -B package --file pom.xml
+```
+
+### Check latest
+In the basic examples above, the `check-latest` flag defaults to `false`. When set to `false`, the action tries to first resolve a version of Java from the local tool cache on the runner. If unable to find a specific version in the cache, the action will download a version of Java. Use the default or set `check-latest` to `false` if you prefer a faster more consistent setup experience that prioritizes trying to use the cached versions at the expense of newer versions sometimes being available for download.
+
+If `check-latest` is set to `true`, the action first checks if the cached version is the latest one. If the locally cached version is not the most up-to-date, the latest version of Java will be downloaded. Set `check-latest` to `true` if you want the most up-to-date version of Java to always be used. Setting `check-latest` to `true` has performance implications as downloading versions of Java is slower than using cached versions.
+
+For Java distributions that are not cached on Hosted images, `check-latest` always behaves as `true` and downloads Java on-flight. Check out [Hosted Tool Cache](docs/advanced-usage.md#Hosted-Tool-Cache) for more details about pre-cached Java versions.  
+
+
+```yaml
+steps:
+- uses: actions/checkout@v2
+- uses: actions/setup-java@v2
+  with:
+    distribution: 'adopt'
+    java-version: '11'
+    check-latest: true
+- run: java -cp java HelloWorldApp
+```
+
+### Testing against different Java versions
 ```yaml
 jobs:
  build:
-    runs-on: ubuntu-16.04
+    runs-on: ubuntu-20.04
    strategy:
      matrix:
