Groovy Builder转换真的有效吗？

我尝试在以下代码中使用转换：

plugins {
    id 'groovy'
    id 'java'
}

group 'org.example'
version '1.0-SNAPSHOT'

sourceCompatibility = 11

repositories {
    mavenCentral()
}

dependencies {

    implementation 'org.codehaus.groovy:groovy-all:2.4.15'
    testCompile group: 'junit', name: 'junit', version: '4.12'
    testImplementation ('org.spockframework:spock-core:1.1-groovy-2.4') {
        exclude group: 'org.codehaus.groovy'
    }
}

错误：

package pattern

import spock.lang.Specification

class HttpRequestBuilderAnnotationSpec extends Specification {

    private String url = 'https://dsd.com'

    void "Instantiate HttpRequest"() {

        when:
        HttpRequestBuilderAnnotation httpRequestBuilderAnnotation = HttpRequestBuilderAnnotation.builder()
                                                                    .url(url).build()

        then:
        assert httpRequestBuilderAnnotation
        assert httpRequestBuilderAnnotation.getUrl() == url
    }
}

----------注:

如果删除了“private”修饰符，代码就可以运行了，但我相信根据Groovy规范，private修饰符应该按原样工作。

这是否回答了您的问题？不是真的。我只是尝试将生成器转换用于一个普通的Fluent API风格的方法，但是您使用的是带有不可变（final）字段的默认策略。

package pattern

import spock.lang.Specification

class HttpRequestBuilderAnnotationSpec extends Specification {

    private String url = 'https://dsd.com'

    void "Instantiate HttpRequest"() {

        when:
        HttpRequestBuilderAnnotation httpRequestBuilderAnnotation = HttpRequestBuilderAnnotation.builder()
                                                                    .url(url).build()

        then:
        assert httpRequestBuilderAnnotation
        assert httpRequestBuilderAnnotation.getUrl() == url
    }
}

groovy.lang.MissingMethodException: No signature of method: static pattern.HttpRequestBuilderAnnotation.url() is applicable for argument types: (java.lang.String) values: [https://dsd.com]
