== Intro ==

[http://www.eclipse.org/ Eclipse] ([http://wiki.eclipse.org/Main_Page wiki site]) is an open source community whose projects are focused on building an open development platform comprised of extensible frameworks, tools and runtimes for building, deploying and managing software across the application development lifecycle. A large and vibrant ecosystem of major technology vendors, innovative start-ups, universities, research institutions and individuals extend, complement and support the Eclipse platform.

[http://www.eclipse.org/ Eclipse] is an open source community whose projects are focused on building an open development platform comprised of extensible frameworks, tools and runtimes for building, deploying and managing software across the application development lifecycle. A large and vibrant ecosystem of major technology vendors, innovative start-ups, universities, research institutions and individuals extend, complement and support the Eclipse platform.

As the project, community and resources are numerous, this page serves to note specific information that will help you use and interact with the technology most efficiently '''with a focus on the PHP developer'''.

The http://wiki.eclipse.org/PDT/Installation site offers good details on getting a clean and fully updated installation working, especially if you have particular needs for an older version. Similarly, this HOWTO seems like it's complete and tested, although I didn't follow it. http://www.howtoforge.com/setting-up-eclipse-pdt2.0-on-eclipse3.4-ganymede

== ~~Components~~ ==

== Features ==

The word "features" in the eclipse world refers to '''components''' that you can install on top of the core platform. It is the components which are actually the things that allow you to do the things you think of when "using" eclipse. Features in eclipse is similar to the concept of installing applications on top of an operating system.

As a [http://www.eclipse.org/home/categories/languages.php Language IDE] eclipse offers tools for just about every programming language (click on "Related EPIC [http://www.eclipseplugincentral.com/ Plugins]" in the bottom panel). It has also expanded beyond what you might consider when you think "Integrated Development Environment" to include not just advanced tools like UML modeling, but even support for Service Oriented Architectures.

=== Remote System Explorer ===

The '''Target Management (RSE)''' feature allows you to operate on your remote systems like it was the local system, and includes a shell where you can execute commands plus process monitor and more.

[http://subclipse.tigris.org/ Subclipse] is an Eclipse Team Provider plug-in providing support for Subversion within the Eclipse IDE. [http://www.newt.com/java/eclipse/ this Eclipse HOWTO] covers subclipse installation and a couple other initial configuration items. I believe with the release of Ganymede (2008) that subversion integration is included, so I'd have to learn what the differences are between the subclipse project, and any subversion integration which is pre-packaged with the eclipse platform.

Subclipse 1.4.6 is now available for Eclipse 3.2+ (Eclipse 3.2/Callisto, 3.3/Europa, 3.4/Ganymede +)

By default, the Eclipse Update Manager will not update you to a new minor release. In other words, if you have release 1.0.3 installed, it will update you to a 1.0.4 release, but it will not update you to a 1.1.0 or 1.2.0 release. You can change this in the Eclipse preferences.

== Zend Studio for Eclipse ==

Zend Studio ~~and other IDEs are~~ similar to the PDT, but ~~are~~ not free.

== Alternates ==

Aside from installing Eclipse and plugins "the good old-fashioned way", you can also find many Vendor-supplied gratis distributions usually with a hook into their revenue-generating business.

=== Aptana Studio ===

http://www.aptana.com/studio

Their no-cost version is pretty complete, and the pro version is almost as cheap as they come at $99 The pro version adds SFTP capability which I don't understand since you can get Target Management RSE for free -- and the latter seems more powerful from the description. I don't use it, and haven't compared Aptana to the free Eclipse, but I figured I'd mention it in case someone is looking for a product that comes with paid technical support.

=== Polarion ===

Polarion offers some additional features for use with Subversion such as LDAP authentication

http://www.polarion.com/products/eclipse/

=== Zend Studio for Eclipse ===

Zend Studio is similar to the PDT (in fact they originated or contribute to the PDT project), but it is not free.

note too that the discovery site URIs should be added to the eclipse software under " help -> software updates -> add site " for software discovery. The endpoints for these URIs are not formatted for human reading.

In addition to installing Eclipse, you should definitely be sure to set the Java environement

<~~source~~ lang="bash">

sudo update-java-alternatives --list

</~~source~~>

</syntaxhighlight>

That command should list something like

<pre>

Line 110:

Line 144:

</pre>

Then you can set the Sun Microsystems Java as the default with

<~~source~~ lang="bash">

sudo update-java-alternatives --set java-6-sun

</~~source~~>

</syntaxhighlight>

To upgrade, you should be able to just

# start eclipse

# click Help (Alt + h)

# click Software Updates (s)

# click Update (Alt + d)

=== Trouble Upgrading ===

<pre>

The software items you selected may not be valid with your current installation.

Do you want to open the wizard anyway to review the selections?

</pre>

If I uncheck everything but the SDK from the update list, then that error message goes away. However the update would stall and hang at 22% complete - presumably because the HTTP client within eclipse has problems. So, I installed an experimental feature which supposedly takes care of this. I eventually got the SDK to update, but I'm still unable to update the '''WST Server Core''' or other WST components.

<pre>

Cannot complete the request. See the details.

Cannot find a solution satisfying the following requirements Match[requiredCapability:

org.eclipse.equinox.p2.iu/org.apache.commons.logging/[1.0.4.200809231229,1.0.4.200809231229]].

</pre>

I get the same error message with the WSDL 1.4 and 1.5 Feature
