You may get an error if you upgrade to 1.1.7+. Because assertjGenerator configuration was removed for bugfix #12.

Please configure assertjGenerator at assertjGenPreConfig instead.

your build.gradle

ext {
+    assertjGenPreConfig = [
+        "assertjGenerator": "xxx"
+    ]
}

assertjGen {
-    assertjGenerator = 'xxx'
}

See Gradle - Plugin: com.github.opengl-BOBO.assertjGen

This plugin add assertjGen task.

This task generates Assertion Classes by AssertJ Assertions Generator.

build.gradle

buildscript {
    ...
}

apply plugin: 'java'

// You must declare a custom 'sourceSets' configuration before include 'assertjGen' plugin.
// Because, 'assertjGen' plugin needs to read 'sourceSets' at it was loaded. 
sourceSets {
    foo.java.srcDirs { "src/main/foo" }
    bar.java.srcDirs { "src/main/bar" }
}

ext {
    // This property must be declared before to apply plugin ("apply plugin: 'com.github.opengl-BOBO.assertjGen'").
    // Because assertjGen plugin needs read these options before define tasks.
    assertjGenPreConfig = [
        // specify AssertJ Assertions Generator dependency. (default is ver 2.0.0)
        'assertjGenerator': 'org.assertj:assertj-assertions-generator:2.0.0',
        // specify sourceSets names. (default is ['main'])
        'sourceSets': ['main', 'foo', 'bar']
    ]
}

apply plugin: 'com.github.opengl-BOBO.assertjGen'

repositories {
    // Plugin uses an 'assertj-assertions-generator' module.
    // Therefore specified repository must have the module.
    mavenCentral()
}

assertjGen {
    // specify target class or package names by array. (defailt is empty array)
    classOrPackageNames = ['foo.bar']
    
    // specify output dir(String path or File object). (default is 'src/test/java-gen')
    outputDir = 'src/test/foo-bar'
}

At least you must set classOrPackageNames option.

If you want output files into a directory that includes handmade files (e.g. src/test/java), please set cleanOnlyFiles option to true.

assertjGen {
    classOrPackageNames = ['foo.bar']
    outputDir = 'src/test/java'
    cleanOnlyFiles = true
}

If cleanOnlyFiles option is false (default is false), assertjClean task deletes all files under an outputDir.
So handmade files will be deleted.

If cleanOnlyFiles option is true, assertjClean task only deletes matched files by cleanFilesPattern option.
cleanFilesPattern option is regular expression. Its default value is /^.*Assert\.java$/.

This task generates assertion classes.

compileTestJava -> assertjGen -> assertjClean and compileJava

So you run test task, then assertjGen task is also run.

This task deletes generated classes (*.java files).

If you run clean task, then assertjClean task is also run.

You may get an error if you upgrade to 1.1.4+. Because repositories configuration was removed for bugfix #8.

AssertjGen.groovy

- project.repositories {
-     mavenCentral()
- }

Therefore Gradle will lose a repositories configuration, if you had not configured repositories and upgrade to 1.1.4+.

Please configure repositories explicitly.

your build.gradle

+ repositories {
+     mavenCentral()
+ }
