I have SDKMAN 5.7.3+337 on an Ubuntu 18.10 which is listing these available versions for java:
13.ea.17-open > * 10.0.2-open 1.0.0-rc-12-grl
12.0.1-zulu * 9.0.7-zulu 1.0.0-rc-11-grl
12.0.1-librca 9.0.4-open 1.0.0-rc-10-grl
12.0.1-sapmchn 8.0.212-zulu 1.0.0-rc-9-grl
12.0.1-open 8.0.212-amzn 1.0.0-rc-8-grl
+ 12.0.0-open 8.0.212-librca
11.0.3-sapmchn + 8.0.202-zulu
11.0.3-zulu 8.0.202.j9-adpt
11.0.3-amzn 8.0.202.hs-adpt
11.0.3-librca 8.0.202-zulufx
+ 11.0.2-open 7.0.222-zulu
11.0.2.j9-adpt 6.0.119-zulu
11.0.2.hs-adpt 1.0.0-rc-15-grl
11.0.2-zulufx 1.0.0-rc-14-grl
10.0.2-zulu 1.0.0-rc-13-grl
while the same SDKMAN version on an Ubuntu 18.04.1 LTS (as WSL in Windows 10) shows:
13.ea.17-open * 9.0.4-open 1.0.0-rc-11-grl
12.0.1-sapmchn 8.0.212-zulu 1.0.0-rc-10-grl
12.0.1-zulu 8.0.212-amzn 1.0.0-rc-9-grl
12.0.1-open 8.0.212-librca 1.0.0-rc-8-grl
12.0.1-librca + 8.0.202-zulu
11.0.3-sapmchn 8.0.202.j9-adpt
11.0.3-zulu 8.0.202.hs-adpt
11.0.3-amzn 8.0.202-zulufx
11.0.3-librca + 8.0.191-oracle
11.0.2.j9-adpt 7.0.222-zulu
11.0.2.hs-adpt 6.0.119-zulu
11.0.2-zulufx 1.0.0-rc-15-grl
10.0.2-zulu 1.0.0-rc-14-grl
10.0.2-open 1.0.0-rc-13-grl
9.0.7-zulu 1.0.0-rc-12-grl
where 11.0.2-open is missing. Why this happens and how should I solve this?
PS: I already run sdk selfupdate and sdk update
It seems that downloading the missing version:
wget https://download.java.net/java/GA/jdk11/9/GPL/openjdk-11.0.2_linux-x64_bin.tar.gz
then unpacking to:
~/.sdkman/candidates/java/
then renaming the extracted directory:
mv ~/.sdkman/candidates/java/jdk-11.0.2 ~/.sdkman/candidates/java/11.0.2-open
solves the problem.
PS: of course, you'll have to change ~/.sdkman/candidates/java/ to match your SDKMAN installation path (if not the default one)
