Eclipse plugin: can't install 1.1.25

[MaximeJo]

Dear all,

I have tried to install the Plant UML Eclipse plugin using "Help -> Install New Software" method with link http://hallvard.github.io/plantuml/. It gets to the last "Installing Software" phase and, at about 50%, pops up the following error:

An error occurred while collecting items to be installed
session context was:(profile=epp.package.java, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

I've tried with two different Eclipse releases, 2020-06 and Oxygen 1.a, and they both featured the same error.

Any idea of what I'm doing wrong?

Also, is there a place where I could manually download the Eclipse plugin files (either from 1.1.25 or an older version)?

Thanks in advance, Maxime

I assume this is a temporary problem with github serving the files. The files are available in the gh-pages branch in the repo at github.com/hallvard/plantuml

Thank you very much @hallvard !!

I managed to install the plugin manually. The "lib" plugin must be installed before the "eclipse" one otherwise an error occurs.
