Spotbug task fails on CI with error "java.io.IOException: error=7, Argument list too long"

[parveen-bhatia]

Hi, i am using gradle plugin for the android project with below build.gradle.

plugins {
  id 'com.github.spotbugs' version '6.0.12'
  ...
}

apply plugin: "com.github.spotbugs"

spotbugs {
  toolVersion = '4.8.4'
  showStackTraces = true
  ignoreFailures = true
  useAuxclasspathFile = true
  reportsDir = file("$project.rootDir/spotbugs/reports")
  effort = Effort.MAX
  baselineFile = file("$project.rootDir/spotbugs/spotbugs_baseline.xml")
  excludeFilter = file("$project.rootDir/spotbugs/project_exclude.xml")
}

tasks.withType(SpotBugsTask) {
  group 'Verification'
  description 'Run Spotbugs on this project.'
  useAuxclasspathFile = true
  classes = files("${project.buildDir}/intermediates/javac/standardRelease")
  reports {
    xml.enabled(true)
    html.enabled(true)
  }
}

On my local with MacOS, ./gradlew spotbugsStandardRelease task works successfully and able to generate reports.
However on CI (which uses linux based docker with eclipse-temurin-17), i am getting below error:

Following is the list of versions:

• Gradle Version: 8.5
• AGP Version: 8.1.1
• Spotbugs Plugin: 6.0.12

I tried enabling useAuxclasspathFile = true, which is as per #243. But still getting the issue.

Could you run your build with --debug option, then it will print the argument applied to the build.

spotbugs-gradle-plugin/src/main/kotlin/com/github/spotbugs/snom/internal/SpotBugsRunner.kt

Line 106 in ca33175

log.debug("Arguments for SpotBugs are generated: {}", this)

Thanks for the response.

I haven't provided -sourcepath value below, as this is sensitive information (LIST_NOT_PROVIDED_SENSITIVE_INFO) but -sourcepath value is around ~190605 chars

Hi @KengoTODA or @rpalcolea any idea what can be wrong or anything else i can try. Please let me know if any more information is required.

[KengoTODA]

Currently SpotBugs has no sourcepathFromFile or similar solution, so what I can suggest is just to shorten the sourcepath.
