Warning "Unable to create a system terminal" when running maven daemon about maven-mvnd HOT 17 CLOSED

It's probably the library jansi-1.18.jar which is missing from the classpath...

from maven-mvnd.

I was able to reproduce on a Windows VM. I can see jansi-1.18.jar in the lib/ext folder of the distro:

from maven-mvnd.

As lazy as I am to start my Windows VM, @Dunemaster could you please check if the problem still exists with the freshly released mvnd 0.0.6? https://github.com/mvndaemon/mvnd/releases/tag/0.0.6

from maven-mvnd.

@ppalaga it fails with Windows Defender warning

"Ошибка выполнения Microsoft VBScript: Этот сценарий содержит вредоносное содержимое и был заблокирован антивирусным программным обеспечением" means "Microsoft VBScript error: this scripte contains malicious content and has been blocked by antivirus software"

I think the whole org.jboss.fuse.mvnd.jpm.ProcessImpl class could be easily rewritten with the ProcessHandle Java 9 class, that should avoid relying on VB scripts on windows.

from maven-mvnd.

Using Java 9's ProcessHandle sounds doable. We already use that class in the client. So it would not change the current Java compatibility. Java 11 is required for building the client, but at runtime the native client is Java-agnostic and the server requires Java 8 only.

from maven-mvnd.

That would be even easier. I started adding support for ProcessHandle and the old jpm library in parallel, but it will be easier to get rid of that one.

from maven-mvnd.

FWIW, I am having the same problem in Git Bash (on Windows) with mvnd 0.0.8.

Btw, I am not seeing the "Improved console output" when building Quarkus. Is this due to the "dumb terminal"?

from maven-mvnd.

@famod could you run with the --debug option and paste the output ? and yes, if the terminal can't be created correctly, the output will certainly be very messy.

from maven-mvnd.

I'll test tomorrow if this helps #117

from maven-mvnd.

could you run with the --debug option and paste the output ?

Will do later this week.

and yes, if the terminal can't be created correctly, the output will certainly be very messy.

Well, not at all messy, I just don't see "the status of each build thread on a separate line" (quoted from README).

PS: Now that I read "jansi":

$ echo $MAVEN_OPTS
-Djansi.passthrough=true -XX:TieredStopAtLevel=1 -Xverify:none

Not sure this is of any help.

Doesn't look very helpful, or does it?

from maven-mvnd.

It does not. I do think the problems comes from the native libraries, so we need to sort that first.

from maven-mvnd.

export TERM=xterm fixed it for me so I guess you are right that it is related to Jansi.
I am now also seeing the condensed status messages!

Fix confirmed, thanks!
