Eclipse version: Version: Oxygen.2 Release (4.7.2)

OS: Mac OS High Sierra(10.13.6 (17G65))

I just read through the interesting blog about how this plugin came into picture and I am excited to use this plugin on my eclipse. But somehow it doesn't decompile. It was installed without a problem but it doesn't show up under Java in Preferences(as in Screenshot). 

What is wrong here?

Need help! Thanks in advance.

I failed to install onto Eclipse JEE Mars, with error message below:

Unable to read repository at ecd-plugin.github.io/update/content.xml.
Received fatal alert: protocol_version

This tool really works. I manage to save an old project (written on java 8). Thanks! It read also lambda expressions without problem.

By the way I use Oxygen.3a Release (4.7.3a).

Happy coding!

Class decompiler not working. Could anyone help on this.

vpanushevj87's picture

Works fine when opening a .class file from the project tree.

But when I'm debugging an application and reach a file for which I don't have a source, the decompiler editor is not opened. Instead I see a "Source not found." editor with "Edit Source Lookup Path.." button.

.class and .class without source are associated with the Class Decompiler Viewer as suggested in the documentation.


Any setting that I missed. 

Eclipse Neon.3 Release (4.6.3)

Hi Guys

Everytime I try to download the plugin via MarketPlace, I get the following error:

Unable to read repository at url: ecd-plugin.github.io/update/content.xml.
sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target


I am using Eclipse Oxygen 1a (4.7.1a), please assist.....

I cannot reach the repository either with the same error message. Navigating with a browser takes me to a 403 page.

This is a misleading error message from eclipse and is usually triggered by a errornous network configuration - in fact, in can be any network problem.

Did you check if you need a proxy configured in Eclipse? If the problem persist, navigate manually to https://ecd-plugin.github.io/update/ download the jar files and place them in the features and plugins folde rof your eclipse installation.

There is no problem with the ECD installation. However the option "Window | Preferences | Jave | Decompiler" is missing / not shown; and jar decompilation is not working

Thank you for your feedback. Did you try to install ECD on a clean Eclipse, and are the ECD features listed in the About dialog?

To simplify the development process, please report bugs at https://github.com/ecd-plugin/ecd/issues

As stated on https://github.com/ecd-plugin/ecd/issues/17, the problem was fixed by removing any old EclipseCD leftovers and reinstalling the extension.
