See the https://projects.spring.io/spring-credhub/[project site] for more information. === Demo Application A simple application that demonstrates the use of Spring CredHub is available in link:/spring-credhub-demo[this repository]. == Building === Basic Compile and Test To build the source you will need to install JDK 1.6. Spring CredHub uses Maven for most build-related activities, and you should be able to get off the ground quite quickly by cloning the project you are interested in and typing ---- $ ./mvnw install ---- NOTE: You can also install Maven (>=3.3.3) yourself and run the `mvn` command in place of `./mvnw` in the examples below. If you do that you also might need to add `-P spring` if your local Maven settings do not contain repository declarations for spring pre-release artifacts. NOTE: Be aware that you might need to increase the amount of memory available to Maven by setting a `MAVEN_OPTS` environment variable with a value like `-Xmx512m -XX:MaxPermSize=128m`. We try to cover this in the `.mvn` configuration, so if you find you have to do it to make a build succeed, please raise a ticket to get the settings added to source control. === Working with the code If you don't have an IDE preference we would recommend that you use http://www.springsource.com/developer/sts[Spring Tools Suite] or http://eclipse.org[Eclipse] when working with the code. We use the http://eclipse.org/m2e/[m2eclipe] eclipse plugin for maven support. Other IDEs and tools should also work without issue as long as they use Maven 3.3.3 or better. ==== Importing into eclipse with m2eclipse We recommend the http://eclipse.org/m2e/[m2eclipe] eclipse plugin when working with eclipse. If you don't already have m2eclipse installed it is available from the "eclipse marketplace". NOTE: Older versions of m2e do not support Maven 3.3, so once the projects are imported into Eclipse you will also need to tell m2eclipse to use the right profile for the projects. If you see many different errors related to the POMs in the projects, check that you have an up to date installation. If you can't upgrade m2e, add the "spring" profile to your `settings.xml`. Alternatively you can copy the repository settings from the "spring" profile of the parent pom into your `settings.xml`. ==== Importing into eclipse without m2eclipse If you prefer not to use m2eclipse you can generate eclipse project metadata using the following command: [indent=0] ---- $ ./mvnw eclipse:eclipse ---- The generated eclipse projects can be imported by selecting `import existing projects` from the `file` menu. == Contributing Spring CredHub is released under the non-restrictive Apache 2.0 license, and follows a very standard Github development process, using Github tracker for issues and merging pull requests into master. If you want to contribute even something trivial please do not hesitate, but follow the guidelines below. === Sign the Contributor License Agreement Before we accept a non-trivial patch or pull request we will need you to sign the https://cla.pivotal.io/sign/spring[Contributor License Agreement]. Signing the contributor's agreement does not grant anyone commit rights to the main repository, but it does mean that we can accept your contributions, and you will get an author credit if we do. Active contributors might be asked to join the core team, and given the ability to merge pull requests. === Code of Conduct This project adheres to the Contributor Covenant link:/CODE_OF_CONDUCT.adoc[code of conduct]. By participating, you are expected to uphold this code. Please report unacceptable behavior to spring-code-of-conduct@pivotal.io. === Code Conventions and Housekeeping None of these is essential for a pull request, but they will all help. They can also be added after the original pull request but before a merge. * Use the Spring Framework code format conventions. If you use Eclipse you can import formatter settings using the `eclipse-code-formatter.xml` file from the link:/etc/ide/eclipse-code-formatter.xml[project]. If using IntelliJ, you can use the http://plugins.jetbrains.com/plugin/6546[Eclipse Code Formatter Plugin] to import the same file. * Make sure all new `.java` files to have a Javadoc class comment with at least an `@author` tag identifying you, and preferably at least a paragraph on what the class is for. * Add the ASF license header comment to all new `.java` files (copy from existing files in the project) * Add yourself as an `@author` to the .java files that you modify substantially (more than cosmetic changes). * Please include unit tests. * If no-one else is using your branch, please rebase it against the current master (or other target branch in the main project). * When writing a commit message please follow http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html[these conventions], if you are fixing an existing issue please add `Fixes gh-XXXX` at the end of the commit message (where XXXX is the issue number).
