eHour is mainly developed in Java 7 and Scala. As of eHour 1.4.2, the intention is not to to add any new
eHour has a classic 3-tier architecture with a persistence layer (eHour-persistence), service layer (eHour-service) and view layer (eHour-wicketweb).
eHour's source is versioned at Github: https://github.com/te-con/ehour
Gitflow is loosely followed: the current released version is in master while the version being developed is in the develop branch. The nightly builds are build from the develop branch. Any features that take a considerable amount of time to develop lives in a feature/<feature name> branch. After the feature is finished that branch is merged into the develop branch.
The code is divided in a number of modules:
|Maven module name||Description|
|eHour-audit||Contains the aspect for the audit log. Only one annotation is in this module but the annotation is used by the service and web tier|
|eHour-common||Contains common functionality and all the domain objects. Domain objects are shared between the 3 tiers.|
|eHour-jetty||The embedded Jetty server as used by the standalone version and the selenium end-to-end tests|
|eHour-persistence||The data access objects for all supported databases, the Derby (embedded DB) validator and Derby native SQL queries.|
|eHour-persistence-mysql||The MySQL native SQL queries plus MySQL SQL scripts.|
|eHour-persistence-postgresql||Ditto for Postgresql|
|eHour-selenium||End-to-end tests with Selenium|
|eHour-service||The service tier with all the business logic|
|eHour-standalone||The assembly package and install4j scripts for building the standalone executables|
|eHour-war||The assembly package for building the WAR|
|eHour-wicketweb||The view tier|
The reason for splitting out eHour-web and eHour-wicketweb is the different packaging for the standalone and WAR distribution.
To build with Maven 3, use the standard "mvn clean install".
Apart from the default build there are two profiles:
|prod||mvn clean install -Pprod||Builds the ehour-<version>-war.zip. The standalone executables are built with install4j 5 however the license file cannot be shared.|
|e2e||mvn clean install -Pe2e||Builds and executes the end-to-end Selenium tests.|
The Scala classes take a while to compile. To speed up compile time over multiple iterations, you might want to run a Zinc compile server. Download Zinc from https://github.com/typesafehub/zinc and run it in before compiling with Maven. In Maven's output you will see a message that the Zinc compile server is being used.
Clone the source and open the POM file as a project. For Scala support you want to have the Scala plugin installed.
To run eHour from IntelliJ, create a runtime configuration like:
