Introduction
This how-to deals with creating a plug-in that is part of the Orion SDK - one that is stored, built and used in the Orion client. For a how-to on creating a plug-in in general, please see the Simple Plug-in Example.
The remainder of this how-to assumes a few things:
- You have already created a plug-in and that you want to hook all of the pieces up to make it part of the SDK. As an example the new
org.eclipse.orion.client.javascript
plug-in will be referenced. - You have the Orion client repository checked out, and the projects imported in your workspace.
- You have some familiarity with Ant buildfiles and editing them.
Put the code in the client
When you add a plug-in to the SDK, you could add the code a couple of ways:
- Add the code in the
org.eclipse.orion.client.ui/web/plugins/
folder, update the defaults.prefs file and have it built as part of the client UI bundle. - Add the code as a separate bundle that will be built separately and lives in the
org.eclipse.orion.client/bundles/
folder.
This how-to assumes you want to create a separate bundle and have placed your plug-in code in the org.eclipse.orion.client/bundles/
folder. For example the JavaScript plug-in is found in the org.eclipse.orion.client/bundles/org.eclipse.orion.client.javascript/
folder.
Configure build.properties
The build.properties
file must be created / edited to tell Orion what you would like to be built.
The most common cases will have two entries:
- bin.includes - what should be included in the binary-only build
- src.includes - what should be included in the source build
The JavaScript plug-in, for example, has the following entries:
bin.includes = META-INF/,\ bundle.properties,\ web/ src.includes = web/,\ about.html
A word of caution here, your bin.includes
entry must contain the root to where your plug-ins' HTML resides or the build will fail stating it cannot find your plug-in.
Add a POM.xml file
Since Orion is moving towards a completely Tycho / Maven-based build, your plug-in will also require a pom.xml
file to indicate how it should be built. For more information on POM files please see the Maven POM file introduction.
First we add some information about our plug-in:
- groupId - this will be have the value
org.eclipse.orion
- artifactId - this is the identifier of your plug-in from its MANIFEST.MF file, for example
org.eclipse.orion.client.javascript
- version - this is the version of your plug-in from its MANIFEST.MF file with
-SNAPSHOT
added after the end. For example the JavaScript plug-in has the version1.0.0.qualifier
which would be entered as1.0.0-SNAPSHOT
in the POM file. - packaging - this is how the plug-in should be packaged, the value is typically
eclipse-plugin
Secondly, we add some information about the parent:
- groupId - this is the value
org.eclipse.orion
- artifactId - this is the client parent identifier
org.eclipse.orion.client.parent
- version - this is the client parent version, which currently is:
1.0.0-SNAPSHOT
- relativePath - this is the path relative to the parent, which is
../..
As an example, the complete POM.xml for the JavaScript plug-in looks like:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>org.eclipse.orion</groupId> <artifactId>org.eclipse.orion.client.javascript</artifactId> <version>1.0.0-SNAPSHOT</version> <packaging>eclipse-plugin</packaging> <parent> <groupId>org.eclipse.orion</groupId> <artifactId>org.eclipse.orion.client.parent</artifactId> <version>1.0.0-SNAPSHOT</version> <relativePath>../..</relativePath> </parent> </project>
Update the defaults
To have your plug-in show up installed by default in Orion (see testing Orion plugins for more information) you will want to add an entry to the org.eclipse.orion.client.ui/web/defaults.pref
file.
The entry is based off the root of where your plug-in provides its packages (more on this in update the site information section) and specifies if the plug-in should be started automatically. For example, the JavaScript plug-in adds the entry: "javascript/plugins/javascriptPlugin.html":true
. This entry points to the HTML file for the plug-in which is based off the root supplied in the site configuration and also indicates that the plugin should be automatically started.
The path entered here appended to the path from the site configuration must point directly to your plug-ins' HTML file. For example the JavaScript plugin has the org.eclipse.orion.client.javascript/web/
path in its site configuration, making the full path to the plugin HTML file: org.eclipse.orion.client.javascript/web/javascript/plugins/javascriptPlugin.html
.
