NPE in EclipseXmlFormatterStepImpl.java / PREFERENCE_FACTORY is null

See original GitHub issue

NPE in EclipseXmlFormatterStepImpl.java at line 64

Saw this on one of our build machines, but could not reproduce locally on a 4-core laptop. Happened after a retrigger of the build (due to environmental issues). Reproduced twice in a row (retriggering the Jenkins build), and a third time after submitting a new patch. Only seen it in one repo so far, we have other repos (around 10) where XML formatting works like a charm

Command line used from Jenkins is

gradle --parallel build check -PuniqueSchema=true --info

Judging from the code (albeit only checked master), PREFERENCE_FACTORY is null, meaning that the static method setupFramework() either has not been called (yet), or SpotlessEclipseFramework.setup() returned false for some reason

This is the spotless version: classpath group: ‘com.diffplug.spotless’, name: ‘spotless-plugin-gradle’, version: ‘3.24.2’

This is the spotless configuration:

  spotless {
        java {
            googleJavaFormat('1.7')
            licenseHeaderFile file("$project.rootProject.projectDir/config/license.java")
        }
        format 'gradle', {
            target '**/*.gradle'
            trimTrailingWhitespace()
            indentWithSpaces(2)
            endWithNewline()
        }
        format 'xml', {
            target fileTree('.') {
                include 'tests/**/*.xml'
                exclude '**/build/**'
            }
            eclipseWtp('xml').configFile("$project.rootProject.projectDir/config/spotless.xml.prefs")
        }
    }

The xml prefs are standard eclipse prefs:

user@host> cat config/spotless.xml.prefs
eclipse.preferences.version=1
indentationChar=space
indentationSize=2
lineWidth=200
user@host>

Thanks for the GitHub trick, @nedtwigg! I’ll see if I can try out the “quick-n-dirty” solution on our build machines on Monday (just adding a synchronized modifier). I’d be happy to share thoughts about redesign of the initialization parts, if @fvgh becomes available, just ping me in this case. Thanks for unleashing spotless onto the world 😃
