nextVersion and snapshotSuffix ignored when using new plugin syntax

[colindean]

This is likely user error, as I'm still pretty new to Gradle.

My incredibly pared down build.gradle, untested in this context:

plugins {
  id 'scala'
  id "com.cinnober.gradle.semver-git" version "2.2.2" // semantic versioning from git
}
apply plugin: 'scala'
ext {
  nextVersion = "patch"
  snapshotSuffix = "-dev-<count>-g<sha>"
}
apply plugin: "com.cinnober.gradle.semver-git"
task printVersion << {
  println project.ext.properties.containsKey("nextVersion")
  println project.ext.properties.get("nextVersion")
  println project.ext.nextVersion
  println project.ext.snapshotSuffix
  println project.version
}

I have a tag I created with git tag -a 99.9.9 -m "Test tag for testing". I have one commit more on top of it.

I expect the output of ./gradlew printVersion to contain 99.9.10-dev-1-gd34db33f or something similar. It instead prints something like this:

:printVersion
true
patch
patch
-dev-<count>-g<sha>
99.10.0-SNAPSHOT

I pretty certain that I have ext in the right place, but it appears not to be effective. What do I need to change?

I'm on Gradle 2.10.

[mojocinn]

Strange. You usage is more or less exactly how we use semver-git internally. You could try to apply semver-git with:

allprojects {
    ext.nextVersion = 'patch'
    ext.snapshotSuffix = "-dev-<count>-g<sha>"
    apply plugin: "com.cinnober.gradle.semver-git"
}

since that is how it is generally applied here, though it seems to me that your build file should work.

[colindean]

Unfortunately, that still doesn't work. I'm going to try a barebones project and see what I can make happen. It's entirely possible that something else in our build.gradle is acting up.

[colindean]

I'm able to reproduce it with the barebones config.

mkdir gradlewtf && cd gradlewtf
atom build.gradle

Put this in build.gradle:

plugins {
  id 'scala'
  id "com.cinnober.gradle.semver-git" version "2.2.2" // semantic versioning from git
}
apply plugin: 'scala'
ext {
  nextVersion = "patch"
  snapshotSuffix = "-dev-<count>-g<sha>"
}
apply plugin: "com.cinnober.gradle.semver-git"

Some exploration to try:

gw showVersion # behavior undefined, since we're not yet in a git repo
gw --version
git init .
git add build.gradle
git commit -m "Initial commit"
git tag -a 1.0.0 -m "Initial"
git describe
gw showVersion # 1.0.0 expected
echo ".gradle" >> .gitignore
git add .gitignore
git commit -av -m "Adds gitignore"
gw showVersion # 1.0.1-dev-1-gd34db33f or other hash expected

My output:

As you can see, at the end, it's defaulting to bumping minor and -SNAPSHOT.

I've also tried switching to the java plugin in case the scala plugin does something weird. No difference.

Hi Colin,

The project.version is assigned by semver-git when the plugin is applied. This means that the related properties must to be set before that step.

/Mikael

[colindean]

I reversed the order so that the application of semver-git happens before anything else:

plugins {
  id 'java'
  id "com.cinnober.gradle.semver-git" version "2.2.2" // semantic versioning from git
}
ext {
  nextVersion = "patch"
  snapshotSuffix = "-dev-<count>-g<sha>"
}
apply plugin: "com.cinnober.gradle.semver-git"
apply plugin: 'java'

My configuration is still having no effect.

Thrashing a bit, I tried adding a buildscript block, but apparently that's not a valid approach since buildscript cannot contain a plugins block.

[colindean]

I'm not sure what else I can change. @mbrannstrom @mojocinn, what version of Gradle are you using?

[colindean]

OK, some progress:

buildscript {
  repositories {
    maven {
      url "https://plugins.gradle.org/m2/"
    }
  }
  dependencies {
    classpath "com.cinnober.gradle:semver-git:2.2.2"
  }
}

plugins {
  id 'java'
//  id "com.cinnober.gradle.semver-git" version "2.2.2" // semantic versioning from git
}

ext.nextVersion = "patch"
ext.snapshotSuffix = "-dev-<count>-g<sha>"

apply plugin: "com.cinnober.gradle.semver-git"
apply plugin: 'java'

This works, and so does this:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath group: 'com.cinnober.gradle', name: 'semver-git', version: '2.2.0'
    }
}

plugins {
  id 'java'
//  id "com.cinnober.gradle.semver-git" version "2.2.2" // semantic versioning from git
}

ext.nextVersion = "patch"
ext.snapshotSuffix = "-dev-<count>-g<sha>"

apply plugin: "com.cinnober.gradle.semver-git"
apply plugin: 'java'

I can't remember exactly, but I think I found semver-git through the Gradle plugins page for semver-git and used the newer syntax. It works when I use the older syntax provided there, or the syntax (with an error fixed, submitting that momentarily) version of what's on this repo's README. I'm thinking that Gradle's newer plugins infrastructure doesn't load the plugin at the right time.

[colindean]

Probably the take-away from this is a modification to the README which states NOT to use the newer plugins way of including it.

[mbrannstrom]

The newer way plugins { id .. } has other problems as well. For example it does not work inside a submodules block, not for any gradle plugin.

It is an experimental feature, and I suggest always using the old buildscript { repositories .. } with apply plugin: ... syntax, because first it will be on the top level, then someone will move it to e.g. a submodules block, and then it won't work.

[colindean]

Thanks for the insight.

I just got bit by this again on a new project. Is there any way to detect that it's running, or perhaps output some debug logging to show what it's doing? I probably burned 30 minutes trying to figure out what was incorrectly configured because someone else did it this time.

[deepy]

@colindean if you move the ext {} into your buildscript {} this should work

If you want a simple debug, try

task version doLast {task -> println "This is $task.project.name $task.project.version" }
