ADT-Install seems not to work :-(

[JoachimRees]

I try to install ABAP Cleaner to my ADT, as instructed:

ADT, select menu 'Help / Install New Software...', copy the link https://sap.github.io/abap-cleaner/updatesite to the 'Work with' field and follow the installation steps

However, then a I get an error[1]:

Unable to read repository at https://sap.github.io/abap-cleaner/updatesite/content.xml.

PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Hi Joachim,

hm, the URL looks correct on your screenshot, but it works for me (and apparently many others), so it doesn't seem to be an issue specific to ABAP cleaner, but rather a missing certificate on your machine – not at all my area of expertise, unfortunately. Let me try to find a colleague who knows more about it.

(Meanwhile, have you tried searching the web for "PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"?)

Kind regards,
Jörg-Michael

@JoachimRees:
Some component in your network (antivirus, firewall, corporate proxy, ...) is hooking into encrypted TLS connections.

The fake certificate of this component needs to be trusted by the operating system / application.

Typically this is done by injecting a trusted root certificate into the Windows operating system trust store. However, Eclipse, in its default configuration, does not make use the Windows OS trust store but uses the trust store of the Java VM.

To change this, and have Eclipse use the OS trust store, you can set the following two options in eclipse.ini after -vmargs:

-Djavax.net.ssl.trustStore=NONE
-Djavax.net.ssl.trustStoreType=Windows-ROOT

@JoachimRees I can confirm that some corporate networks may have probnlems with it ;-)

Maybe you have the chance to do the install after workhours while using your ordinary home network.
This always works for me.

Awesome, this did it! Works fine now, thanks a lot!

Hi Joachim,

great, thanks for your feedback! I shall then create a "known installation issues" page and link to it from the installation instructions.

Kind regards,
