【中文标题】新的 jooq/gradle 配置不生成任何 jooq 类【英文标题】:new jooq/gradle configuration not generating any jooq classes 【发布时间】:2018-12-27 03:17:53 【问题描述】:我得到了一个使用 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:

我开始使用 jooq API 并意识到我使用的是旧版本的 jooq,所以想切换到较新的 API。
我尝试的第一件事是将两个 jooq 引用从 3.8.1 更改为 3.11.2。这引起了问题,因为 jooq 版本似乎更改了 API,因此 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 块不在顶部,从我在终端和在线看到的情况来看,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
所以我不知道该示例将如何工作,除非它适用于与我所拥有的不同版本的 gradle(之前或之后)。
查看 jooq-gradle 插件 (https://github.com/etiennestuder/gradle-jooq-plugin) 的文档,其中包含设置 gradle 脚本的非常清晰的步骤,因此我将 build.gradle 文件修改为如下所示:

运行“gradle run”工作正常,所以我假设它正在下载新版本的 jooq,但现在我没有看到任何代码生成。我看到以下消息:
$ gradle generateSampleJooqSchemaSource
:generateSampleJooqSchemaSource UP-TO-DATE
谁能告诉我:
我正在为此使用适当的 gradle-jooq 插件吗? 是否错误地配置了先前版本的新生成器语法?【问题讨论】:
【参考方案1】:关于您手动设置 jOOQ 代码生成器
确实,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。在您的手动设置中,您需要从以下位置更改导入:
import org.jooq.util.jaxb.*
import org.jooq.util.*
到
import org.jooq.codegen.*
import org.jooq.meta.jaxb.*
import org.jooq.meta.*
关于您使用第三方 Gradle 插件
请注意,架构名称区分大小写,因此可能有助于替换它:
inputSchema = 'public'
由此
inputSchema = 'PUBLIC'
你之前已经正确了:.withInputSchema("PUBLIC")
【讨论】:
是外壳!太感谢了。我现在需要阅读该功能以便我能理解它,但我很欣赏这个简单的修复。实际上,我从示例中复制了该粘贴并注意到了它,但我认为这并不重要,因为我是从示例中提取的。 @voodoogiant:“实际上是从示例中复制粘贴并注意到它,但我认为这并不重要,因为我从示例中提取了它”,是的,PostgreSQL 报告不区分大小写的名称为小写,其他数据库将它们报告为大写:-/以上是关于新的 jooq/gradle 配置不生成任何 jooq 类的主要内容,如果未能解决你的问题,请参考以下文章
