Finally singed up for bintray and published my first artifact. Much nicer to use than sonatype.

  • Internet says there is a nice feature for "Signing with the Bintray Key" but i don’t see to have that option.

    • So, had to generate my own.

    • To export my keys from gpg:

      gpg --armor --export 632B9183
      gpg --armor --export-secret-keys BE07FA4E

maven release plugin

First time doing a release, and thus github might no be in known_hosts, fails with this error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-release-plugin:2.5.2:prepare (default-cli) on project padersprinter-query: Unable to tag SCM
[ERROR] Provider message:
[ERROR] The git-push command failed.
[ERROR] Command output:
[ERROR] ssh_askpass: exec(/usr/sbin/ssh-askpass): No such file or directory
[ERROR] Host key verification failed.
[ERROR] fatal: Could not read from remote repository.

added to known_hosts by testing on command-line: git ls-remote -h git@github.com:38leinaD/padersprinter-query.git HEAD

So, release:prepare always tagged the SNAPSHOT version because no commit was happening before it. Seems to be a known issue; see stackoverflow. Tried a lot of version; the only combination that worked was this:


Also read the following articles on how to build/release with maven following CI/CD approach. Different but both interesting:

Using gitflow plugin for gitflow see also like a handy plugin.
