I'm using eclipse 2022.06 and Git integration for eclipse 6.0.0 (egit) I saw other issues with the handshake error message but they were years old and on Java 7. I'm using

eclipse.buildId=4.24.0.I20220607-0700
java.version=11
java.vendor=Oracle Corporation
BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=en_US
Framework arguments:  -product org.eclipse.epp.package.jee.product
Command-line arguments:  -os win32 -ws win32 -arch x86_64 -product org.eclipse.epp.package.jee.product

• I tried setting http.sslVerify=false already.
• I also tried changing the HTTP client and the SSL agent in eclipse preferences | git and that didn't help.
• command line git to gitlab will work
• using egit to github will work too, but not to gitlab
• the last time I connected to gitlab successfully thru egit was before I upgraded to eclipse 2022.06

Answer 1

I found my answer. I had changed eclipse to use jdk 11 instead of the jre 17 that it came with. When I changed eclipse it back to using jdk 17 it worked again. There must be something about gitlab's git repo and it's SSL requirements thats requiring the higher java version.
