【问题描述】：

我是 gradle 和 spring boot 的新手。最近我创建了一个项目，它使用了 spring boot、spring websocket、spring jdbc 和其他一些 jar 依赖项。完整的build.gradle如下：

buildscript 
    repositories 
        mavenCentral()
        mavenLocal()
    
    dependencies 
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.5.RELEASE")
    


apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'spring-boot'

sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories 
    mavenCentral()
    mavenLocal()


sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies 
    compile("org.apache.commons:commons-lang3:3.4")

    compile("org.springframework.boot:spring-boot-starter-websocket")
    compile("org.springframework:spring-messaging")
    compile("org.springframework:spring-jdbc:4.2.1.RELEASE")

    compile("com.oracle:ojdbc7:7")

    compile('org.checkerframework:checker:1.9.5')
    compile('org.checkerframework:checker-qual:1.9.5')


task wrapper(type: Wrapper) 
    gradleVersion = '2.3'

运行 gradle bootRun 时出现以下错误：

Exception in thread "main" java.lang.IllegalStateException: Could not evaluate condition on org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration#transactionManager due to internal clas
s not found. This can happen if you are @ComponentScanning a springframework package (e.g. if you put a @ComponentScan in the default package by mistake)

第一行说应用程序无法从类路径开始，然后列出了那里几乎所有的依赖 jar。

有人遇到过这种情况吗？

【问题讨论】：

Tom，如果有帮助，我在调用依赖项时看到 this answer's syntax 与您的不同...不过我不熟悉 gradle。

【参考方案1】：

我解决了这个问题。

compile("org.springframework:spring-jdbc:4.2.1.RELEASE")

改成

compile("org.springframework:spring-jdbc")
