grails3.3 升级grails4 问题解决

需要注意，如果引入插件，需要确认查看插件版本，有需要升级的要升级版本，否则各种问题

需要注意：

需要手动在build.gradle中添加相关依赖包

如果出现执行报错：

则手动将gradle包从3.5升级到gradle5就可以了，即：

更改为

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

再运行：

./gradlew wrapper --gradle-version 5.0

如果出现以下报错，则：

需要修改build.gradle

buildscript {
    repositories {
        mavenLocal()
        maven { url "https://repo.grails.org/grails/core" }
    }
    dependencies {
        classpath "org.grails:grails-gradle-plugin:$grailsVersion"
        classpath "org.grails.plugins:hibernate5:7.0.0"
        classpath "org.grails.plugins:views-gradle:1.2.9"
        classpath "gradle.plugin.com.energizedwork.webdriver-binaries:webdriver-binaries-gradle-plugin:$webdriverBinariesVersion"
    }
}

需要把初始化数据放到service里面，然后引用，其实也就是需要有事务

如果是service报错，需要在service上添加事务注解

@Transactional

注意：

升级Grails4.0.1后，可能启动时卡主，卡在：compileGroovy,如图：

或者

接着你们会发现风扇呼呼呼，，，，最后，内存溢出

运行：grails compile --verbose

一直在重复，直到内存溢出，

解决办法：官方回复

Set the following properties in gradle.properties

.gradle.properties

org.gradle.daemon=true
org.gradle.parallel=true
org.gradle.jvmargs=-Xmx1024M

In build.gradle file set the forkOptions for compileGroovy task as:

.build.gradle

compileGroovy.groovyOptions.forkOptions.jvmArgs = ['-Xmx1024m']

idea启动报错，

但是，直接Application.groovy里面启动是可以的

个人感觉解决方式有点勉强，但是应该有更好的解决办法，没办法，技不如人，自己又找不到问题所在，只能先用着了，，，哎（技不如人，技不如人，技不如人）
