Error while using self compiled openJDK14 in eclipse

[Manavjeet Singh]

Hi!
I compiled OpenJDK-14 on my machine and it is working fine when used from
the command line. I want to build a program using it but when trying to add
it to Eclipse(v4.18) through Window->Preferences->Installed
JREs->Add->StandardVM and giving the path
jdk14/build/linux-x86_64-server-release/jdk/.
But it is showing the error: "Target is not a JDK root. System library not
found".
Have I made some mistake while compiling the jdk? Any help would be
appreciated.
Thanks
