I have gotten Eclipse 2020-06 installed under Windows 10 and have also gotten it to recognize and "update" my Project from Eclipse Oxygen.
I need to install Red Hat Tools and neither it nor installation of other Red Hat add ons is working. Everything fails with "unable to read repository".
For example, I have tried to install using both the Eclipse Marketplace and Help Install New Software for:
JBoss Tools, Code Ready Studio and I get:
Unable to read repository at https://devstudio.redhat.com/12/stable/composite/12.16.0/compositeContent.xml
Unable to read repository at https://download.jboss.org/jbosstools/oxygen/updates/content.xml
Unable to read repository at https://download.jboss.org/jbosstools/photon/updates/content.xml
Unable to read repository at https://download.jboss.org/jbosstools/2020-06/updates/content.xml
Connection to http://download.jboss.org/jbosstools/photon/staging/updates/central/4.16.0.Final/p2.index failed on Received fatal alert: internal_error. Retry attempt 0 started
All of the attemps show the following in the Errors log :
javax.net.ssl.SSLException: Received fatal alert: internal_error
at java.base/sun.security.ssl.Alert.createSSLException(Alert.java:129)
at java.base/sun.security.ssl.Alert.createSSLException(Alert.java:117)
When I am using Install New Software I get the above error as soon as I selet the (Red Hat related) Work With item.
I can reach the internet with the Eclipse "embedded" browser. In Install New Software I can select non-Red Hat packages and see all of the available modules. I have deleted the cache at p2\org.eclipse.equinox.p2.repository\cache and I have Removed and added back the Source for Red Hat Tools (as above).
My searches have resulted in numerous older posts with suggestions that a proxy is causing the problem but I don't see how that can be the case. This is failing on a home network with no proxy and the Windows 10 system Eclipse is running on does not have a proxy set up.
Can someone suggest why this is failing?
Thank you in advance.
Many thanks to howlger! I had a bad install of the JDK. I started fresh, installed AdoptOpenJDK's .msi, installed Eclipse and am finally able to install CodeReady Studio (includes Jboss Tools). Thanks again very much!
