Cannot Install Cloud Tools for Eclipse - javax.servlet 2.5.0 could not be found

[WilliamRisser]

I am following the instructions on https://cloud.google.com/eclipse/docs/quickstart

When I attempt to install the Cloud Tools for Eclipse from the Eclipse Marketplace, I encounter the error:

Cannot complete the install because one or more required items could not be found. Software being installed: Google Cloud Platform for Eclipse 1.8.5.202108061424 (com.google.cloud.tools.eclipse.suite.feature.feature.group 1.8.5.202108061424) Missing requirement: Cloud Tools for Eclipse App Engine Local Server 0.1.0.202108052157 (com.google.cloud.tools.eclipse.appengine.localserver 0.1.0.202108052157) requires 'osgi.bundle; javax.servlet 2.5.0' but it could not be found Cannot satisfy dependency: From: Google Cloud Platform for Eclipse 1.8.5.202108061424 (com.google.cloud.tools.eclipse.suite.feature.feature.group 1.8.5.202108061424) To: org.eclipse.equinox.p2.iu; com.google.cloud.tools.eclipse.appengine.localserver [0.1.0.202108052157,0.1.0.202108052157]

I am running Eclipse
Version: 2022-06 (4.24.0)
Build id: 20220609-1112

Running Eclipse with vm jdk-11.0.15.
Windows 10.

How do I get Cloud Tools for Eclipse to install?

Thanks

The error says the Cloud Tools for Eclipse (CT4E) requires Servlet 2.5.0, and it doesn't seem available in newer Eclipse versions. Admittedly, 2.5.0 is super old.

In any case, people reported that CT4E doesn't work with recent Eclipse versions.

We've seen Eclipse remove old versions of Hamcrest from current repos, too, causing similarish issues.

We solved this using Eclipse 2021-09, install the Cloud Tools and update Eclipse afterwards. So I have 2022-12 with cloud tools running. Maven had some problems with this, but they are gone for now.

Installing Eclipse 2021-09 does no longer seem to be a solution. After installing Eclipse 2021-09 and trying to install Google Cloud Tools, an error message appears:

Tested on Windows 11 and MacOS 13.4 with the same results.

Results the same to me. I install the 2021-09 version of eclipse but the instalation of Google Cloud Tools give me the same error.

Someone knows how to solve it?

Same here, with Eclipse 2021-09:

session context was:(profile=epp.package.jee, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

What gives? 🤔

I can confirm that it works with 4.15
