Hi @shershen08 and thank you for giving MsgViewer a try!
I presume you are using an obsolete version of the JDK.
You can check the version with the following command: java -version
MsgViewer required JDK version 11 at least.
You may fetch the latest JDK here: https://jdk.java.net/

FreeBSD here, I can't remove OpenJDK 8 without also removing Apache Maven.

Hi @grahamperrin !

I'm not used to FreeBSD but according to this https://www.freebsd.org/cgi/man.cgi?query=javavm&sektion=&manpath=freebsd-release-ports
you can have different Java versions installed simultaneously. All you would have to do is specifying which version you want to use with
env JAVA_VERSION=11+
Note there was a bug with java version > 1.9 that was fixed one year ago : https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=237054
Could you try invoking env JAVA_VERION=11+ java -version ?

Multiple versions already installed:

root@mowa219-gjp4-8570p:~ # pkg query '%o %v %R' openjdk8 openjdk11
java/openjdk8 8.275.01.1 FreeBSD
java/openjdk11 11.0.9+11.1_2 FreeBSD

– but I needed a nudge to read the relevant manual page.

So:

$ uname
FreeBSD
$ cd ~/Applications/MsgViewer
$ JAVA_VERSION="11" mvn package

– but no matter; I have the BUILD SUCCESS above. Thanks 👍

Note to self: need to sh before JAVA_VERSION="11" ⋯ commands e.g.

JAVA_VERSION="11" java -jar /home/grahamperrin/Applications/MsgViewer/MSGViewer/target/msgviewer.jar

Yeah, my syntax was approximative :)
Anyway, I'm happy you could run MsgViewer. Looking forward to reading your feedback
