On the Edge: PHP IDE With Eclipse Galileo (3.5 M6) and PDT 2.1 M6

Eclipse 3.5 AKA Galileo is scheduled for release on the 24th June 2009, with PDT 2.1 shortly after on the 26th. Not being one to wait, and also getting some obscure pleasure from testing pre-release software, I decided to download and install the current stable Milestone, M6, of both Eclipse Galileo and PDT 2.1. The whole process is fairly simple, and even more so for 32 bit users, who have an All-In-One package available, which can be downloaded, extracted and run easily.

64 Bit users have a little more work to do, but the process is not too difficult. First, we have to download the relevant packages, and all the dependencies:

• Eclipse gtk 3.5M6 200903130100 (64 Bit)
• PDT 2.1.0M6 Runtime
• EMF 2.5.0M6 S200903161215
• DLTK (Core) R1.0 1.0M6 200903161640
• DLTK (RSE) R1.0 1.0M6 200903161640
• GEF 3.5.0M6 S200903161602
• WTP (WST) 20090318020101 R3.1 3.1M6
• XSD 2.5.0M6 S200903161215

I downloaded them all to a directory called “Galileo” on my Desktop. The rest of the process uses the command line, so open up a Terminal, and navigate to the directory containing the downloaded files:

cd ~/Desktop/Galileo

The first task is to extract the main Eclipse package, and optionally move it to a new home – I chose to install it in ~/galileo/eclipse

tar -zxvf eclipse-SDK-3.5M6-linux-gtk-x86_64.tar.gz
mkdir /home/[USERNAME]/galileo
mv eclipse /home/[USERNAME]/galileo

Eclipse has utilised the p2 Installer, and a “dropins” directory – which is scanned by the p2 Installer whenever Eclipse is executed – since Ganymede 3.4M6. If p2 finds any Features or Plugins, they are installed upon startup. The p2 Installer also allows placing plugins into their own directory structures within the dropins directory, making installing, organising and testing plugins much easier. Of course, this isn’t as easy as using the Update Manager, but it’s very convenient for our purposes of testing pre-release plugins, since they can easily be deleted/upgraded etc. Anyway, I digress – my original point was that we need to extract, and organise each of the packages downloaded above, then move them into the dropins directory:

DLTK Core:

cd ~/Desktop/galileo
unzip dltk-core-sdk-S-1.0M6-200903161640-incubation.zip
mkdir dltk-core & mv eclipse/ dltk-core

DLTK RSE:

unzip dltk-rse-sdk-S-1.0M6-200903161640-incubation.zip
mkdir dltk-rse & mv eclipse/ dltk-rse

EMF:

unzip emf-runtime-2.5.0M6.zip
mkdir emf & mv eclipse/ emf

GEF:

unzip GEF-SDK-3.5.0M6.zip
mkdir gef & mv eclipse/ gef

PDT:

unzip pdt-runtime-2.1.0M6.zip
mkdir pdt & mv eclipse/ pdt

WTP-WST:

unzip wtp-wst-sdk-S-3.1M6-20090318020101.zip
mkdir wtp & mv eclipse/ wtp

XSD:

unzip xsd-runtime-2.5.0M6.zip
mkdir xsd & mv eclipse/ xsd

Finally, we need to move all these new directories containing the plugins, to the Eclipse dropins directory:

mv dltk-core dltk-rse emf gef pdt wtp xsd /home/[USERNAME]/galileo/eclipse/dropins/

That’s the installation complete. We now just need to run Eclipse with the -clean option. This may take a while as p2 scans the dropind watch directory for the new plugins:

cd /home/[USERNAME]/galileo/eclipse
./eclipse -clean

Since it’s the first time we’re running Eclipse, it’ll also ask where the Workspace directory is located. I just chose /home/[USERNAME]/galileo/workspace to keep everything together.

Once Eclipse is loaded, click the “Workbench” button, then go to the Window -> Open Perspective -> Other menu, and select PHP.

The same method can be used to install and test the Nightly Builds of PDT 2.1 – just visit http://www.eclipse.org/pdt/downloads, expand the latest link under the 2.1.0 Nightly Builds heading, download the latest build and the required dependencies, and install using the same methods outlined here.
