JDK-8 support

[holgerstolzenberg]

Hey,

I am using the gradle-pitest-plugin under JDK-8 with Gradle-1.11. Here is my declaration from build.gradle:

buildscript {
  repositories {
    mavenCentral()
  }
  dependencies {
    classpath 'org.springframework.boot:spring-boot-gradle-plugin:' + springBootVersion
    classpath 'info.solidsoft.gradle.pitest:gradle-pitest-plugin:0.32.0'
  }
}

pitest {
  //dependencies {
  //  compile 'org.ow2.asm:asm:5.0'
  //}

  pitestVersion = "0.33"
}

The test execution fails with the following exception:

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':dashboard-server:pitest'.

I already read some blog posts and it seems like this problem relates to an invalid ASM library. I tried to declare a dependency directly to the pitest task but that does not help. On my default class path there is an ASM library version 3.3.1 because of a transitive dependency of QueryDSL.

pitest - The Pitest libraries to be used for this project.
\--- org.pitest:pitest-command-line:0.33
     \--- org.pitest:pitest:0.33
          +--- junit:junit:4.10
          |    \--- org.hamcrest:hamcrest-core:1.1
          \--- org.testng:testng:6.1.1
               +--- junit:junit:3.8.1 -> 4.10 (*)
               +--- org.beanshell:bsh:2.0b4
               +--- com.beust:jcommander:1.12
               \--- org.yaml:snakeyaml:1.6

I noticed that the 'pitest' classpath does not include a specific ASM version.

Any advice would be pretty much appreciated.

Thanks for the report!

The problem is in fact with old asm version, but PIT has embedded (and relocated) asm version (see package in a stacktrace at org.pitest.reloc.asm.ClassReader.<init>(Unknown Source)) and as of 0.33 this is 5.0_BETA (which supports Java 8 bytecode). It took me awhile to get know what is the reason (I was focused on the old asm version in PIT, but it was perfectly fine).

The problem is that a mechanism in the plugin which allows to change default PIT version doesn't work properly and even though it passes to PIT good (overridden) version the default version do the plugin is used. For 0.32.0 it was 0.32 which doesn't support Java 8 bytecode (has old embedded asm).

As a workaround I uploaded gradle-pitest-plugin 0.33.0-SNAPSHOT (available in Sonatype snapshot repository) which fixes your problem (by using 0.33 as a default version). I will release 0.33.0 when I fix the core problem with dependencies.

Btw, I tested the plugin with Java 8 before 0.33 was released, but I was using the new snapshot version which had PIT 0.33 set as a default version :).

[holgerstolzenberg]

Thanks for your reply.

I just tested against the SNAPSHOT version of the plugin and everything works fine! Good work so far. As I am using this for production code, when do you think will 0.33.0 plugin be released?

[szpak]

There is a problem with the classpath which is used to call a static bootstraping method in PIT from my plugin and a classpath which PIT uses to set up its deamons/workers. It is possible to use PIT 0.33 with gradle-pitest-plugin 0.32.0 with the following configuration:

buildscript {
    (...)
    dependencies {
        classpath('info.solidsoft.gradle.pitest:gradle-pitest-plugin:0.32.0') {
            exclude(group: 'org.pitest')
        }
        classpath 'org.pitest:pitest-command-line:0.33'
    }
}

pitest {
    pitestVersion = "0.33"
}

but I would like to allow user to just define requested version in pitestVersion parameter (which is something I am working on, but currently only with various problems and I'm not sure if it would be possible without writing a custom class loader to bootstrap PIT...).

[holgerstolzenberg]

I have tried your workaround, and the build succeeds, but now I am getting an exception during the test run. That did not happen with the SNAPSHOT plugin version. I am also wondering why the build does not break. I will provide the stack trace for further analysis. For the moment, I will fallback to the SNAPSHOT plugin.

BUILD SUCCESSFUL

Hm, the last comment is not fully correct. I recognised a small miss configuration of my build script. Still, a clean 0.33.0 plugin release is pretty much appreciated :-).

[szpak]

I evaluated a few possible solutions (including Gradle internal classes) and at the end after a consultation with Peter Niederwieser I decided to use JavaExec task which launches PIT as a separate Java process (with a separate classpath) what fixes an ability to override PIT version. There is a new mainProcessJvmArgs parameter, but as PIT itself starts child processes for mutation analysis there usually should be no need to use it (e.g. to increase available memory).
I uploaded a snapshot version 0.33.0-SNAPSHOT. Could you give it a try and tell me if this version work for you out-of-box?

Btw, the another solution would be needed to support EntryPoint and the new extended plugin support in PIT (the would be not more static main method), so maybe when needed there would be implemented the solution with custom classloader - we will see.

[szpak]

Btw, for consistency I changed also jvmArgs configuration parameter type from String to List<String>. This can cause a ClassCastException exception if you already used it in your project. Unfortunately I coudn't find a way to support both String and List<String> as input types for the same parameter.

Hey szpak,

I just tried it and it works so far. Thanks a lot. This is the configuration I am using currently.

ext {
   pitestPluginVersion = "0.33.0-SNAPSHOT"
}

buildscript {
  dependencies {
    classpath("info.solidsoft.gradle.pitest:gradle-pitest-plugin:" + pitestPluginVersion)
  }
}

pitest {
  threads = 6
}

I am getting some errors printed to the console when running, but the test suite runs through:

stderr  : objc[39759]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Home/jre/bin/java and /Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. stderr  : Which one is undefined.

From my side, the release can be made.

[holgerstolzenberg]

Okay I have to correct myself. The plugin SNAPSHOT Version breaks mit 'bootRun' task. I have to dig deeper into it to provide some more details on that.

[holgerstolzenberg]

Finally I had to revert back to plugin version 0.32.0. The error that occurred is very weird. With the following configuration, everything works fine, I can execute pitest and bootRun tasks without problems:

buildscript {
  repositories {
    maven { url "https://ci.it.ewerk.com/nexus/content/groups/public" }
  }

  dependencies {
    classpath "org.springframework.boot:spring-boot-gradle-plugin:1.0.1.RELEASE"

    classpath("info.solidsoft.gradle.pitest:gradle-pitest-plugin:0.32.0") {
      exclude group: "org.pitest"
    }
    classpath "org.pitest:pitest-command-line:0.33"
  }
}

Using the following configuration breaks my build:

buildscript {
  repositories {
    maven { url "https://ci.it.ewerk.com/nexus/content/groups/public" }
  }

  dependencies {
    classpath "org.springframework.boot:spring-boot-gradle-plugin:1.0.1.RELEASE"

    classpath("info.solidsoft.gradle.pitest:gradle-pitest-plugin:0.33.0-SNAPSHOT") {
      exclude group: "org.pitest"
    }
    classpath "org.pitest:pitest-command-line:0.33"
  }
}

Executing the pitest tasks still works without problems, but when I execute the bootRun (Spring Boot porject) task, the embedded jetty launches up without problems, but it does not serve static resources any more.

I have no clue if this is a problem of the spring-boot or the pitest plugin. In the end they should not interfere with each other at all. Did I misconfigure something?
