Hi all,
i have for some reason to use openjdk8 for which i used the
instructions just like if would be jdk-12. Java (jdk8) works pretty
fine so far.
Now i wanted to build ant (as a prerequisite to Tomcat) but failed at
the
$ bootstrap/bin/ant -Ddest=optional -f fetch.xml
command. It reports an error which has something to do with SSL:

Unfortunatly, i'm a real expert in SSL and certificate stuff so i've
no clue what to do and where to look, got stuck here.
Would you mind to point me in a direction to have look?
Btw, its a LFS-9.0 build, make-ca-1.5.
Any ideas on how that could be fixed? Thank you!
It's using the wrong invocation of java (might be able to fix it in the
build, but I really don't remember how). It might be as simple as
symlinking /etc/pki/tls/java/cacerts to /opt/jdk/jre/lib/cacerts or
/opt/jdk/lib/cacerts. Optionally, you can look at the get-m2.xml file
(or loop through it) and manually download the files and just drop them
into lib/optional/ so that the build script doesn't try to do it for
you. Honestly, the best option is probably to drop back to an earlier
ant version to build Tomcat with JDK-8 . Then export the JDK8 and old
ant environment only in the Tomcat environment (just source the
environment files (not in profile.d) directly from the startup script) -
that way you can use newer java and ant for the rest of the system.
