Re: [jetty-users] Completely different behaviour when using maven jetty plugin with and without debug flag
Sorry Jan:
smazahir-mac:jaxrs smazahir$ mvn -v
Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-03T12:39:06-07:00)
Maven home: /usr/local/Cellar/maven/3.5.0/libexec
Java version: 1.8.0_131, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.12.6", arch: "x86_64", family: "mac"

Unfortunately, addding maven logging seems equivalent to the '-X' flag and results in a working server.

The full debug out is pretty large.

For comparison:
Successfully launches jetty server with mvn clean install jetty:run (no other code change): https://pastebin.com/qFVcd7r4

Failed to launch with just mvn clean install jetty:run (has my pom change) -- https://pastebin.com/8gfkA2qD

The debug output is very large and difficult to share.  My intent was to compare a debug output with my change and one without, but since the one with my change somehow succeeds when run with the debug flag I'm a bit stuck.

Doing a simple diff shows there is a lot of noise in the diff (e.g. timestamps) and nothing obvious.

Hi,

You didn't mention the version of jetty, the version of java, the version of maven, nor the os you're running on, so that makes it more difficult to help you.

To help pinpoint the problem, you could edit the $MAVEN_HOME/conf/logging/simplelogger.properties file, and turn on all jetty debug logging by adding a line like: 
org.slf4j.simpleLogger.log.org.eclipse.jetty=DEBUG

Compare the output you get with/without the -X option.

Hi all,

I have a jetty server which runs fine normally.  When I try to add a new POM dependency, the war file fails to get assembled.  When I run the plugin but with the debug switch enabled, the war file get's assembled and run's fine.
That is:

Bad:
mvn clean install jetty:run
mvn clean install jetty:run -Dorg.eclipse.jetty.annotations.maxWait=420
webAppSourceDirectory/Users/smazahir/Workspace/zodiac/touchless_maven_fix/simpleServer/jaxrs/target/swagger-jaxrs-server-1.0.0 does not exist. 

Good:
mvn clean install jetty:run -Dorg.eclipse.jetty.annotations.maxWait=420 -X


What could cause this discrepancy?  How can I debug whether adding a new pom dependency actually causes my project to fail?

Thanks.
