Question

我试图将grails连接到mysql但是我收到了这个错误：

| Loading Grails 2.4.4 | Error There was an error loading the
BuildConfig: Bad artifact coordinates mys

我该如何修复此错误？这是我的buidconfig：

grails.servlet.version = "3.0" // Change depending on target container compliance (2.5 or 3.0) grails.project.class.dir = "target/classes"
grails.project.test.class.dir = "target/test-classes"
grails.project.test.reports.dir = "target/test-reports"
grails.project.work.dir = "target/work"
grails.project.target.level =1.6
grails.project.source.level = 1.6

    war: [maxMemory: 768, minMemory: 64, debug: false, maxPerm: 256, forkReserve:false],
    // configure settings for the Console UI JVM
    console: [maxMemory: 768, minMemory: 64, debug: false, maxPerm: 256] ]

grails.project.dependency.resolver = "maven" // or ivy
grails.project.dependency.resolution = {
    // inherit Grails' default dependencies
    inherits("global") {
        // specify dependency exclusions here; for example, uncomment this to disable ehcache:
        // excludes 'ehcache'
    }
    log "error" // log level of Ivy resolver, either 'error', 'warn', 'info', 'debug' or 'verbose'
    checksums true // Whether to verify checksums on resolve

    repositories {
        inherits true // Whether to inherit repository definitions from plugins

        grailsPlugins()
        grailsHome()
        mavenLocal()
        grailsCentral()
        mavenCentral()
        // uncomment these (or add new ones) to enable remote dependency resolution from public Maven repositories
        //mavenRepo "htt://repository.codehaus.org"

        //mavenRepo "htt://repository.jboss.com/maven2/"
    }

    dependencies {
        // specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes e.g.
        runtime 'mysql:mysql-connector-java:5.1.23-bin'
        // runtime 'org.postgresql:postgresql:9.3-1101-jdbc41'
        test "org.grails:grails-datastore-test-support:1.0.2-grails-2.4"
    }

    plugins {
        // plugins for the build system only
        build ":tomcat:7.0.55"

        // plugins for the compile step
        compile ":scaffolding:2.1.2"
        compile ':cache:1.1.8'
        compile ":asset-pipeline:1.9.9"

        // plugins needed at runtime but not for compilation
        runtime ":hibernate4:4.3.6.1" // or ":hibernate:3.6.10.18"
        runtime ":database-migration:1.4.0"
        runtime ":jquery:1.11.1"

        // Uncomment these to enable additional asset-pipeline capabilities
        //compile ":sass-asset-pipeline:1.9.0"
        //compile ":less-asset-pipeline:1.10.0"
        //compile ":coffee-asset-pipeline:1.8.0"
        //compile ":handlebars-asset-pipeline:1.3.0.3"
    }
}

和datasource：

dataSource {
    pooled = true
    jmxExport = true
    driverClassName = "com.mysql.jdbc.Driver"
    dialect = "org.hibernate.dialect.MySQL5Dialect"
    username = "root"
    password = "thanh" } hibernate {
    cache.use_second_level_cache = true
    cache.use_query_cache = false //    cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory' // Hibernate 3
    cache.region.factory_class = 'org.hibernate.cache.ehcache.EhCacheRegionFactory' // Hibernate 4
    singleSession = true // configure OSIV singleSession mode
    flush.mode = 'manual' // OSIV session flush mode outside of transactional context }

// environment specific settings
environments {
    development {
        dataSource {
            dbCreate = "create-drop" // one of 'create', 'create-drop', 'update', 'validate', ''
            url = "jdbc:mysql:/localhost:3306/bkavr"
        }
    }
    test {
        dataSource {
            dbCreate = "update"
            url = "jdbc:mysql:/localhost:3306/bkav"
        }
    }
    production {
        dataSource {
            dbCreate = "update"
            url = "jdbc:mysql:/localhost:3306/bkav"
            properties {
               jmxEnabled = true
               initialSize = 5
               maxActive = 50
               minIdle = 5
               maxIdle = 25
               maxWait = 10000
               maxAge = 10 * 60000
               timeBetweenEvictionRunsMillis = 5000
               minEvictableIdleTimeMillis = 60000
               validationQuery = "SELECT 1"
               validationQueryTimeout = 3
               validationInterval = 15000
               testOnBorrow = true
               testWhileIdle = true
               testOnReturn = false
               jdbcInterceptors = "ConnectionState"
               defaultTransactionIsolation = java.sql.Connection.TRANSACTION_READ_COMMITTED
            }
        }
    }
}

Answer 1

更改runtime 'mysql:mysql-connector-java:5.1.23-bin'

到

runtime 'mysql:mysql-connector-java:5.1.34'

这应该正确地引入依赖。
