Hi All,
I was trying to build the opentsdb from git url: https://github.com/OpenTSDB/opentsdb.git

After cloning the project, While executing sh build.sh, i was getting below error:

warning: [options] bootstrap class path not set in conjunction with -source 6
error: Source option 6 is no longer supported. Use 7 or later.
make[1]: *** [.javac-stamp] Error 2
make: *** [all] Error 2

try use jdk 1.8?

[Triggergirl]

Hi, where to edit to make the build point to jdk1.8

[johann8384]

I will have to look it up but I have to do items for this and the systemd script. I looked into the systemd script and there is one so now I need to validate why it may not have worked.

I have the same problem as @Triggergirl using ubuntu 20 and java 1.8.0_271.

Do you know any work-around?

Hi, I'm facing the same issue. Here I'm trying to install opentsdb in Ubuntu 20 with Java 1.8, just the same as @avixicu.
Any progression in solving the issue?

Thanks in advance

Hi, did anybody solve this problem?

[manolama]

@vhirk you can edit https://github.com/OpenTSDB/opentsdb/blob/master/Makefile.am#L516 and change the 6 to an 8.

Is anyone unable to use a 1.8 JVM or later? I wouldn't mind toggling it to 8 before cutting 2.4.1 but I want to make sure folks aren't running ancient copies who would be left building their own.

Ubuntu sets differet alternatives for java and javac. Check to see if you have different version than 1.8 for javac and configure it elseways (this changes javac version systemwide though, so don't change in this manner if you're depending on it for other things).

$ sudo update-alternatives --config javac
There are 2 choices for the alternative javac (providing /usr/bin/javac).
