Colorer 0.7.0 won't load in Eclipse 2.1.3

EclipseColorer plugin.xml is compatible only with Eclipse3.0
and higher.

Will make a separate package for 2.1 line.

re-opening since EclipseColorer-take5_0.7.0_eclipse213.zip
won't load either: got this in .log:

apparently 1.5-compiled.

so i tried to import the src into a Eclipse plug-in project, with
some success after adding in the appropriate classpath
variables, but then got hit by these:

The constructor Action(String, int) is undefined
(HRCRegionsTreeView.java:319)
org.eclipse.ui.IPartListener2 cannot be resolved
(HRCRegionsTreeView.java:49)

which seem to exist only since Eclipse 3.0.

Double checked - the code is in JDK 1.4 compatibility mode.
Are you sure you are using jdk >= 1.4 ?

running Eclipse in
Java HotSpot Client VM (build 1.4.0_01-b03, mixed mode)

the eclipse213 binary may well be 2.1.3 compatible, but the
source seems not, which, i think, is reasonable. perhaps a
separate source package for 2.1.3 will help those who have
problem with the binary.

error in Eclipse when opening a JSP file:
