Well, I guess at the end of the day this isn't fully a Flex Mojos
issue as I can SSH into the box and do a maven compile and it runs and
uses xvfb-run correctly. It also runs correctly using the 'regular
method' if I start a VNC server and connect to that and do a compile
from the UI. It only fails when running through Hudson so it appears
there is an issue with that.
However, there does appear to be a bug with <allowHeadlessMode>. In
AsVmLauncher.java there is the useXvfb() function which has three
tests:
protected boolean useXvfb()
{
return allowHeadlessMode && OSUtils.isLinux() &&
GraphicsEnvironment.isHeadless();
}
As the function is returning true it is obvious that all three tests
there are returning true. It also must be true that
GraphicsEnvironment.isHeadless() returns false when I run it from VNC
as it uses the 'regular' method there. So there must be an issue with
allowHeadlessMode.
Even though you don't have a Linux environment to test on, you should
be able to test allowHeadlessMode by temporarily removing the
OSUtils.isLinux() and GraphicsEnvironment.isHeadless() tests. I have
tried it both ways suggested with no success.
<build>
<sourceDirectory>src/main/flex</sourceDirectory>
<testSourceDirectory>src/test/flex</testSourceDirectory>
<plugins>
<plugin>
<groupId>org.sonatype.flexmojos</groupId>
<artifactId>flexmojos-maven-plugin</artifactId>
<version>${flex.mojos.version}</version>
<extensions>true</extensions>
<configuration>
<allowHeadlessMode>false</allowHeadlessMode>
<testRunner>
<launcher>
<allowHeadlessMode>false</
allowHeadlessMode>
</launcher>
</testRunner>
Please let me know if you can test that for me quickly, it would be a
great help
