Gradle PMD Checkstyle Findbugs - Which sourceSet directory to work Java build

Old Forum
1

Gradle 1.6 Linux .

Java build Project structure

•Project_or_Module •src/java (contains java source code)

•test/java (contains JUnit tests - unit tests)

•src/java-test (contains Integration tests)

•etc/etc (other … … folders under the project)

I have the following Global configuration / build.gradle file:

apply plugin: 'java'
   apply plugin: 'pmd'
   apply plugin: 'findbugs'
   apply plugin: 'checkstyle'
   apply plugin: 'code-quality'
   apply plugin: 'jacoco'
     tasks.withType(Compile) {
     options.debug = true
     options.compilerArgs = ["-g"]
   }
     checkstyle {
        configFile = new File(rootDir, "config/checkstyle.xml")
        ignoreFailures = true
   }
       findbugs {
        ignoreFailures = true
   }
     pmd {
        ruleSets = ["basic", "braces", "design"]
        ignoreFailures = true
   }
     jacoco {
      toolVersion = "0.6.2.201302030002"
      reportsDir = file("$buildDir/customJacocoReportDir")
   }
     sourceSets {
      main {
         java {
            srcDir 'src/java'
         }
      }
      test {
         java {
            srcDir 'test/java'
         }
      }
      integrationTest {
         java {
            srcDir 'src/java-test'
         }
      }
   }
     test {
        jacoco {
            append = false
            destinationFile = file("$buildDir/jacoco/jacocoTest.exec")
            classDumpFile = file("$buildDir/jacoco/classpathdumps")
        }
   }
     jacocoTestReport {
         group = "Reporting"
         description = "Generate Jacoco coverage reports after running tests."
         reports {
                xml{
                    enabled true
                    destination "${buildDir}/reports/jacoco/jacoco.xml"
                }
                csv.enabled false
                html{
                    enabled true
                    destination "${buildDir}/jacocoHtml"
                }
        }
        additionalSourceDirs = files(sourceSets.main.allJava.srcDirs)
   }
}

For few of the projects, everything works fine. i.e. when I run “gradle clean build” or “gradle clean build jacocoTestReport”, everything is successful.

For few other projects, I’m seeing the following issues and need help.

  1. “gradle clean build” command works if I remove / comment out the following lines for a project. But when those lines are uncommented like in the code snapshot shown above, then I see errors. Errors are mentioned below after the code snapshot.

   100 errors (similar errors).

You’ll notice here is that the error is coming when Gradle is calling the above task for “src/java-test” folder.

My question1: With those lines commented in the build.gradle file, I never see these errors and “clean build jacocoTestReport” tasks completes successfully but when the code for pmd/findbugs/checkstyle is enabled, I see these errors. Why it’s compiling java-test code. I thought source code is only under src/java (actual java source code for the project: project_or_module)

B. One of the other project ProjectAUtilities is failing at PMD step even thought ignore error is true in build.gradle for pmd. Error says 3 tests failed.

My question2: What configuration should I set for PMD section in build.gradle that will ignore tests if they fail. I think I already has it i.e. ignoreFailures = true

C. How to use include/exclude for Checkstyle/PMD/Findbugs in build.gradle file (not ANT). i.e. it’ll not go and do anything other than “src/java” folder.

Thanks.

There. The following did the trick for all issues i.e. added a sourceSets line and told those 3 tools (pmd/checkstyle/findbugs) to see only main (source code which is “src/java”) under sourceSets definition.

By the way, I took the “sourceSets” section and defined it before the following lines as well.

checkstyle {

configFile = new File(rootDir, “config/checkstyle.xml”)

ignoreFailures = true

sourceSets = [sourceSets.main]

}

findbugs {

ignoreFailures = true

sourceSets = [sourceSets.main]

}

pmd {

ruleSets = [“basic”, “braces”, “design”]

ignoreFailures = true

sourceSets = [sourceSets.main]

}

Btw, the last “}” in the main code shown in the first post (and not in the reply / answer), please ignore that. Actually it was taken from <GRADLE_HOME>/init.d/common.xxx.gradle file and I didn’t copy the following line

allprojects {

thus, last } is not required. In case you want to add the same code in your global gradle common file, then include “allprojects {” line as well.
