I need some help building openhab. I have chosen to checkout v1.8.1 (for no special reason, just thought it was a stable version). Building runs into an error. I am not an expert, but my guess is, that the module uses an old version of apache-common-lang or something like that.
How do I solve this problem?
So I did:
…>mvn checkout v1.8.1
Checking out files: 100% (4259/4259), done.
A bundles/binding/org.openhab.binding.homematic/.settings/org.eclipse.jdt.core.prefs
Previous HEAD position was e83d021… prepare for 1.8.3 release
HEAD is now at 0693e6d… cherry-picked #3950
imac2-vandenzen-nl:openhab carl$ git status
HEAD detached at v1.8.1
Changes to be committed:
(use “git reset HEAD …” to unstage)
new file: bundles/binding/org.openhab.binding.homematic/.settings/org.eclipse.jdt.core.prefs
imac2-vandenzen-nl:openhab carl$ mvn -o clean install
