Question

我正在尝试使用带有gradle的xText和xTend构建创建第一个项目。

我按照xText文档中的指导创建了语法，并创建了xtend生成器。

在eclipse中，代码按预期生成到src-gen文件夹。

当我创建gradle脚本时，也按照http://xtext.github.io/xtext-gradle-plugin/xtext-builder.html构建我的代码，而不是在'src-gen'文件夹中生成代码，它在'build'文件夹中生成。

有没有办法在gradle中将此文件夹从build更改为src-gen？我尝试了很多东西而且总是出错。

完整的成绩脚本代码：

您可以在源集中配置

sourceSets {
   main.xtendOutputDir = 'xtend-gen'
}

e.g。

plugins {
  id "org.xtext.xtend" version "1.0.21"
}

apply plugin: 'java'
apply plugin: 'org.xtext.xtend'

sourceSets {
  main.java.srcDirs = ['src','xtend-gen']
  main.xtendOutputDir = 'xtend-gen'
}

repositories {
    jcenter()
}

dependencies {
    // This dependency is exported to consumers, that is to say found on their compile classpath.
    compile 'org.eclipse.xtext:org.eclipse.xtext.xbase.lib:2.13.0'

}

或用于xtxt构建器插件

buildscript {
    repositories {
        mavenLocal()
            jcenter()
    }
    dependencies {
        classpath 'org.xtext:xtext-gradle-plugin:1.0.21'
    }
}
plugins {
    id "org.xtext.builder" version "1.0.21"
}

repositories {
    mavenLocal()
    jcenter()
}

dependencies {
    xtextLanguages 'org.xtext.example.mydslfoo:org.xtext.example.mydslfoo:1.0.0-SNAPSHOT'
}

xtext {
    version '2.13.0'
    languages {
        mydslfoo {
            setup = 'org.xtext.example.mydslfoo.MyDslFooStandaloneSetup'
            generator {
                outlets {
                    HEROES {              
                    }
                    }
            }
        }
    }
    sourceSets {
        main {
            srcDir 'src'
            output {
                dir(xtext.languages.mydslfoo.generator.outlet, 'src-gen')
                }
        }
    }
  }

使用gradle定义生成器代码位置以构建xtext和xtend
