google一阵，发现大多数人都是打开mxxml文件才出错（貌似是flex的问题），和我的情况稍有不同(汗達達~)

How to setup
Eclipse PDT in linux


Eclipse is a multi-language software development environment
comprising an IDE and a plug-in system to extend it. It is written
primarily in Java and can be used to develop applications in Java and,
by means of the various plug-ins, in other languages as well, including
C, C++, COBOL, Python, Perl, PHP, and others.This tutorial explains how
you can install eclipse in linux with all required modules. First you
need to download the PDT from eclipse site given below.

{codecitation} http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/galileo/R/eclipse-php-galileo-linux-gtk.tar.gz {/codecitation}

PDT is for PHP developers. You can use any other versions
according to the platform you are working in.

Move the tar file
in to /opt folder and extract the file.
{codecitation}
tar -xvzf
eclipse-php-galileo-linux-gtk.tar.gz
{/codecitation}

Now you
have eclipse in /opy/eclipse

You can start eclipse as follows.
{codecitation}
/opt/eclipse/eclipse
&
{/codecitation}

Now you can add aptana plugin which
is a very good plugin that offers code completion and have many
framework supports like jquery, prototype etc.

You can install
this plguin as follows.
{codecitation}
1. Go to Help ->
Install New Software...
2. In the "Work with:" text box, enter: http://update.aptana.com/install/studio 3. Click Add...
4.
Specify the Name of the Update site (i.e. Aptana Studio Plugin)

If you are flex
develper, you can add the flex plugin to eclipse as follows.

Download flex builder from the link given below.
{codecitation} http://labs.adobe.com/downloads/flexbuilder_linux.html {/codecitation}

Give 755 permission to the bin file
{codecitation}
chmod 755
FlexBuilder_Linux_Plugin.bin
{/codecitation}
Run the file
{codecitation}

./FlexBuilder_Linux_Plugin.bin
{/codecitation}
Follow the
prompts to complete the installation.

Start Eclipse.

When
choosing the ‘install folder’ you can leave that to default, the Eclipse
folder will be defined in the next window.

As described select
the Eclipse folder, it must contain a subfolder named ‘configuration’.
Continue the installation untill the installer displays that you’re
done.

Start Eclipse and open the Flex perspective. If you get the
following error while opening a MXML file:
{codecitation}
Could
not open the editor: Assertion failed:
org.eclipse.jface.util.Assert$AssertionFailedException: Assertion failed
{/codecitation}

Make sure you have the correct Eclipse version, I used 3.3.2 on
Ubuntu 9.04.

Now we can configure subversion which is necessary
for a big project.
