gradle - 新的 jooq/gradle 配置不生成任何 jooq 类

标签 gradle h2 jooq

我已经得到了一个使用 gradle (v2.1.0) 和 jooq (v3.8.1) 生成类文件的 Ratpack 应用程序。

这是我的 build.gradle 文件:

buildscript {
  repositories {
    jcenter()
  }
  dependencies {
    classpath "io.ratpack:ratpack-gradle:1.5.4"
    classpath "com.github.jengelman.gradle.plugins:shadow:1.2.3"
    classpath "mysql:mysql-connector-java:5.1.34"
    classpath 'org.jooq:jooq-codegen:3.8.1'
    classpath 'com.h2database:h2:1.4.186'
  }
}

plugins {
    id "com.github.michaelruocco.embedded-mysql-plugin" version "2.1.7"
}

apply plugin: "io.ratpack.ratpack-java"
apply plugin: "com.github.johnrengelman.shadow"
apply plugin: "idea"

// db dump: mysqldump -P 3306 -h 127.0.0.1 -u embedded_user -ppassword --all-databases
def RDS_HOSTNAME = "localhost"
def RDS_PORT = 3306
def RDS_DB_NAME = "test"
def RDS_USERNAME = "embedded_user"
def RDS_PASSWORD = "password"

run {
    environment "RDS_HOSTNAME", RDS_HOSTNAME
    environment "RDS_PORT", RDS_PORT
    environment "RDS_DB_NAME", RDS_DB_NAME
    environment "RDS_USERNAME", RDS_USERNAME
    environment "RDS_PASSWORD", RDS_PASSWORD
}

repositories {
  jcenter()
}

ext {
    ratpackPac4jVersion="2.0.0"
    ratpackVersion="1.5.1"
    pac4jVersion="2.1.0"
}

embeddedMysql {
    url = 'jdbc:mysql://' + RDS_HOSTNAME + ':' + RDS_PORT + "/" + RDS_DB_NAME
    username = RDS_USERNAME
    password = RDS_PASSWORD
    version = 'v5_7_latest'
}

import org.jooq.util.jaxb.*
import org.jooq.util.*

task jooqCodegen {
  doLast {
    String init = "$projectDir/src/main/resources/init.sql".replaceAll('\\\\', '/') 
    Configuration configuration = new Configuration()
      .withJdbc(new Jdbc()
      .withDriver("org.h2.Driver") 
      .withUrl("jdbc:h2:mem:todo;INIT=RUNSCRIPT FROM '$init'") 
    )
      .withGenerator(new Generator()
        .withDatabase(new Database()
          .withName("org.jooq.util.h2.H2Database")
          .withIncludes(".*")
          .withExcludes("")
          .withInputSchema("PUBLIC")
        )
      .withTarget(new Target()
        .withDirectory("$projectDir/src/main/auto_generated") 
        .withPackageName("jooq"))) 
    GenerationTool.generate(configuration)
  }
}

run.dependsOn startEmbeddedMysql

dependencies {
    runtime "org.slf4j:slf4j-simple:1.7.25"

    compile "org.pac4j:ratpack-pac4j:${ratpackPac4jVersion}"
    compile "io.ratpack:ratpack-groovy:${ratpackVersion}"
    compile "io.ratpack:ratpack-test:${ratpackVersion}"
    compile "org.pac4j:pac4j-core:${pac4jVersion}"

    compile "org.pac4j:pac4j-oidc:${pac4jVersion}"
    compile "org.pac4j:pac4j-jwt:${pac4jVersion}"
    compile ratpack.dependency('hikari')
    compile "ch.qos.logback:logback-classic:1.0.13"
    compile group: 'io.ratpack', name: 'ratpack-thymeleaf', version: '1.4.0-rc-3'
    compile "mysql:mysql-connector-java:5.1.34"
    compile 'org.jooq:jooq:3.8.1'
    compile group: 'org.hibernate', name: 'hibernate-core', version: '5.3.2.Final'

}

mainClassName = "xyz.mealsahead.Main"

我开始使用 jooq API 并意识到我使用的是旧版本的 jooq，因此想切换到较新的 API。

我尝试的第一件事就是将两个 jooq 引用从 3.8.1 更改为 3.11.2。这导致了问题，因为 jooq 版本似乎更改了 API，导致 jooq 配置不再起作用:

> startup failed:
  build file build.gradle': 72: unable to resolve class Target 
   @ line 72, column 19.
           .withTarget(new Target()
                       ^

  build file build.gradle': 66: unable to resolve class Database 
   @ line 66, column 23.
             .withDatabase(new Database()
                           ^

  build file build.gradle': 65: unable to resolve class Generator 
   @ line 65, column 22.
           .withGenerator(new Generator()
                          ^

  etc.

jooq 有一个 gradle 设置的示例，但我不明白它是如何工作的:https://www.jooq.org/doc/3.11/manual/code-generation/codegen-gradle/ 。奇怪的是该示例中的 buildscript block 不在顶部，从我在终端和在线中看到的情况来看，这是不允许的:

build.gradle': 24: only buildscript {} and other plugins {} script blocks are allowed before plugins {} blocks, no other statements are allowed

所以我不知道这个例子是如何工作的，除非它适用于与我不同的 gradle 版本(之前或之后)。

查看 jooq-gradle 插件 ( https://github.com/etiennestuder/gradle-jooq-plugin ) 的文档，它有非常清晰的设置 gradle 脚本的步骤，因此我将 build.gradle 文件修改为如下所示:

buildscript {
  repositories {
    jcenter()
  }
  dependencies {
    classpath "io.ratpack:ratpack-gradle:1.5.4"
    classpath "com.github.jengelman.gradle.plugins:shadow:1.2.3"
    classpath "mysql:mysql-connector-java:5.1.34"
    classpath 'com.h2database:h2:1.4.186'
    classpath 'nu.studer:gradle-jooq-plugin:3.0.1'
  }
}

plugins {
    id "com.github.michaelruocco.embedded-mysql-plugin" version "2.1.7"
}

apply plugin: 'nu.studer.jooq'

    username = RDS_USERNAME

}

dependencies {

}

jooq {
    String init = "$projectDir/src/main/resources/init.sql".replaceAll('\\\\', '/') 

  version = '3.11.2'

  sample(sourceSets.main) {

    }
    generator {
      name = 'org.jooq.codegen.DefaultGenerator'
      database {
        name = 'org.jooq.meta.h2.H2Database'
        includes = '.*'
        excludes = ''
        inputSchema = 'public'
      }
      generate {
        relations = true
        deprecated = false
        records = true
        immutablePojos = true
        fluentSetters = true
      }
      target {

        packageName = 'jooq'
      }
    }
  }
}

    compile group: 'org.hibernate', name: 'hibernate-core', version: '5.3.2.Final'

}

mainClassName = "xyz.mealsahead.Main"

运行“gradle run”工作正常，所以我假设它正在下载新版本的 jooq，但现在我没有看到生成任何代码。我看到以下消息:

$ gradle generateSampleJooqSchemaSource 
:generateSampleJooqSchemaSource UP-TO-DATE

有人可以告诉我，如果我:

  • 为此使用合适的 gradle-jooq 插件吗？
  • 错误配置了先前版本的新生成器语法？

最佳答案

关于 jOOQ 代码生成器的手动设置

事实上，由于 jOOQ 3.12 即将模块化，一些拆分包必须重命名，即 org.jooq.util 包。在手动设置中，您需要更改导入:

import org.jooq.util.jaxb.*
import org.jooq.util.*

至

import org.jooq.codegen.*
import org.jooq.meta.jaxb.*
import org.jooq.meta.*

关于您对第三方 Gradle 插件的使用

请注意，架构名称区分大小写，因此可能有助于替换此内容:

inputSchema = 'public'

按此

inputSchema = 'PUBLIC'

您之前已经正确了:.withInputSchema("PUBLIC")
