java - IntrumentModels的任务:冻结模型类

我使用Spark Framework开始了一个小项目，然后选择ActiveJDBC作为其ORM，它使用Gradle构建了所有东西。

(已更新，它正在使用ActiveJDBC 1.4.12)

这是我的build.gradle文件:

buildscript {
    repositories {
        mavenCentral()
        maven { url 'http://repo.javalite.io' }
    }
    dependencies {
        classpath group: 'org.javalite', name: 'activejdbc-gradle-plugin', version: '1.4.13-SNAPSHOT'
    }
}

apply plugin: 'java'
apply plugin: 'org.javalite.activejdbc'

repositories {
    mavenCentral()
}

dependencies {
    compile group: 'org.slf4j',             name: 'slf4j-simple',                       version: '1.7.20'
    compile group: 'com.sparkjava',         name: 'spark-core',                         version: '2.5'
    compile group: 'junit',                 name: 'junit',                              version: '4.12'
    compile group: 'org.postgresql',        name: 'postgresql',                         version: '9.4.1211.jre7'
    compile group: 'org.javalite',          name: 'activejdbc',                         version: '1.4.13-SNAPSHOT'
    compile group: 'org.javalite',          name: 'activejdbc-instrumentation',         version: '1.4.13-SNAPSHOT'
}

task runApp(dependsOn: 'build', type: JavaExec) {
    classpath = sourceSets.main.runtimeClasspath
    main = "my.app.Application"
}

我有一个简单的模型可以访问所有酷模型的方法:

public class User extends Model {}

当我尝试构建项目时，问题开始了:

     Execution failed for task ':instrumentModels'.
        > org.javalite.instrumentation.InstrumentationException: java.lang.RuntimeException: my.app.model.User class is frozen

            * Exception is:

最佳答案

这是几天前已在此处修复的已知错误:https://github.com/javalite/activejdbc/issues/537
请在此处获取最新的1.4.13-SNAPSHOT:http://repo.javalite.io。

更新:

基本上，该异常是由于以下事实:检测插件所使用的Javassist拒绝检测该类，因为该类已经在当前VM中进行了检测。对于无关紧要的项目，这无关紧要，因为该过程会在检测后退出，但Gradle过程会保留下来。该问题已解决，应该可以解决。
