*从 grails 2.5.4 升级到 grails 3.3.11 时出现“无法解决类”问题

Question

我继承了一个基于 Grails 2.5.4 的多模块 grails 应用程序。

运行良好，但我需要升级到 3.x。

我安装了groovy 3.0.4和grails 3.3.11，根据官网(https://docs.grails.org/3.0.x/guide/upgrading.html)提供的教程完成了grails升级任务。

当我尝试构建项目时，我面临多个与基类相关的“无法解决类”问题，例如：

Starting a Gradle Daemon (subsequent builds will be faster)
:compileAstJava NO-SOURCE
:compileAstGroovy NO-SOURCE
:processAstResources NO-SOURCE
:astClasses UP-TO-DATE
:compileJava NO-SOURCE
:configScript
:compileGroovy
startup failed:

我的 myapp.core build.gradle 文件包含以下内容：

buildscript {
    repositories {
        mavenLocal()
        maven { url "https://repo.grails.org/grails/core" }

    systemProperty "webdriver.gecko.driver", System.getProperty('webdriver.gecko.driver')
}

assets {
    minifyJs = true
    minifyCss = true
}

我真的不明白为什么我会收到这些错误，因为相关的依赖项似乎已经到位......我在这里遗漏了什么？

谢谢:)

C:\repo\upgraded-app\myapp-core\grails-app\domain\bittt\holders\Exclusion.groovy： 5：无法解析类org.grails.databinding.BindingFormat@ 第 5 行，第 1 列。导入 org.grails.databinding.BindingFormat

在 Grails 3.3.11 中，包是 grails.databinding，而不是 org.grails.databinding (https://github.com/grails/grails-core/blob/v3.3.11/grails-databinding/src/main/groovy/grails/databinding/BindingFormat.java)。 org.grails.web.servlet.mvc.GrailsParameterMap (https://github.com/grails/grails-core/blob/v3.3.11/grails-web-common/src/main/groovy/grails/web/servlet/mvc/GrailsParameterMap.java) 和 import org.grails.commons.GrailsApplication (https://github.com/grails/grails-core/blob/v3.3.11/grails-core/src/main/groovy/grails/core/GrailsApplication.java) 的包名称也发生了变化。

org.postgresql.core.Query 是一个单独的问题。看起来您的项目没有表达对 postgres 库的依赖关系，因此该类对应用程序不可用。
