-The smallest Java Continuous Integration server for Github
-===========================================================
+# DD2480-CI
+CI is the second assignment in the course DD2480 Software Engineering Fundamentals. The goal of the assignment is to implement a continuous integration server that first clones a repository on GitHub when there are any changes on it, builds the project and notifies the user.
-Here is a tiny CI server skeleton implemented in Java for educational purposes. It is meant to be called as webhook by Github. The HTTP part of it is based on Jetty.
+## Getting Started
+This implementation of a CI-server is made with Java SDK 11 and IntelliJ; therefore make sure you have these installed. The project that uses the CI-server needs to have `Gradle` installed, due to it being used by the CI-server. There must exist a `build.gradle` file in the project. This file must contain the dependencies needed for the project to run.
-We assume here that you have a standard Linux machine (eg with Ubuntu), with Java installed.
+## Testing
+Tests are written using the `JUnit` library.
-We first checkout this repository:
-```
-git clone https://github.com/monperrus/smallest-java-ci
-cd smallest-java-ci
-```
+## Using the CI-server
+1. Go to the assessment branch
+1. Make a change somewhere
+1. Push changes to `GitHub`
+1. The CI-server will do its part and notify about the results
-We then download the required dependencies:
-```
-JETTY_VERSION=7.0.2.v20100331
-wget -U none http://repo1.maven.org/maven2/org/eclipse/jetty/aggregate/jetty-all/$JETTY_VERSION/jetty-all-$JETTY_VERSION.jar
-wget -U none http://repo1.maven.org/maven2/javax/servlet/servlet-api/2.5/servlet-api-2.5.jar
-#For linux users:
-curl -LO --tlsv1 https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-amd64.zip
-unzip ngrok-stable-linux-amd64.zip
-#For Mac user:
-curl -LO --tlsv1 https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-darwin-386.zip
-unzip ngrok-stable-darwin-386.zip
-```
+## What the server is doing
+1. Clone the project using `JGit`, this happens when webhook sees a change (such as a push) in the repository
+1. Compile and run the test using `Gradle` and the Gradle tooling API `GradleConnector` (can be done using the command `gradlew build` in the terminal)
+1. Notify the user using the `XML-file` generated by `Gradle`
-We compile the skeleton the continuous integration server:
-```
-javac -cp servlet-api-2.5.jar:jetty-all-$JETTY_VERSION.jar ContinuousIntegrationServer.java
-```
+## Contributing
+### Branches
+Each issue should be worked on separately in its own branch; issue #420 should only be worked on in the branch `issue-420`. Solutions to issues can only be merged to `master` after a successful review of a pull request.
-We run the server on the machine, and we may make it visible on the Internet thanks to [Ngrok](https://ngrok.com/):
-```
-# open a first terminal window
-JETTY_VERSION=7.0.2.v20100331
-java -cp .:servlet-api-2.5.jar:jetty-all-$JETTY_VERSION.jar ContinuousIntegrationServer
+There are two branches. One `master` and one called `assessment`, the `assessment` branch is simulating a project with a main class and a simple test for it. This is used to show the functionality of the CI-server. The `master` branch is the server part.
-# open a second terminal window
-# this gives you the public URL of your CI server to set in Github
-# copy-paste the forwarding URL "Forwarding http://8929b010.ngrok.io -> localhost:8080"
-# note that this url is short-lived, and is reset everytime you run ngrok
-./ngrok http 8080
+### Documentation
+* Every method should have a `JavaDoc` comment explaining what it does, the parameters and the return value.
-```
+### Statement of Contributions
+_Axel Kennedal_
-We configure our Github repository:
+
+_My Helmisaari_
+ * this README
-* go to `Settings >> Webhooks`, click on `Add webhook`.
-* paste the forwarding URL (eg `http://8929b010.ngrok.io`) in field `Payload URL`) and send click on `Add webhook`. In the simplest setting, nothing more is required.
+
+_Henrik Mellin_
-We test that everything works:
-
-* go to tp check that the CI server is running locally
-* go to your Ngrok forwarding URL (eg ) to check that the CI server is visible from the internet, hence visible from Github
-* make a commit in your repository
-* observe the result, in two ways:
- * locally: in the console of your first terminal window, observe the requested URL printed on the console
- * on github: go to `Settings >> Webhooks` in your repo, click on your newly created webhook, scroll down to "Recent Deliveries", click on the last delivery and the on the `Response tab`, you'll see the output of your server `CI job done`
- * on ngrok: raise the terminal window with Ngrok, and you'll also the see URLs requested by Github
-
-We shutdown everything:
-
-* `Ctrl-C` in the ngrok terminal window
-* `Ctrl-C` in the ngrok java window
-* delete the webhook in the webhook configuration page.
-
-Notes:
-* by default, Github delivers a `push` JSON payloard, documented here: , this information can be used to get interesting information about the commit that has just been pushed.
