运行测试时无法使用spring-boot-starter-web依赖

Question

I have multi-module project using gradle(web,common,batch)

The project is running fine

however when I am trying to run junit from test folder of batch module when the spring comes up I get this:

Caused by: java.lang.NoClassDefFoundError: org/springframework/http/converter/xml/MappingJackson2XmlHttpMessageConverter

I checked dependency tree from the batch module:

<batch>gradle -q dependencies --configuration testRuntime

And I see in the buttom FAILED while trying to import spring-boot-start-web

this is my build.gradle on the batch module:

buildscript {
    repositories {
        maven { url "http://repo.spring.io/libs-release" }
        mavenLocal()
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:$project.ext.springBootVersion")

    }
}

description = 'batch'

dependencies {
    compile("org.springframework.boot:spring-boot-starter-batch:$project.ext.springBootVersion")
    testRuntime("org.springframework.batch:spring-batch-test:$project.ext.springBatchVersion") {
        exclude(module: 'spring-test')
        exclude(module: 'spring-jdbc')
        exclude(module: 'commons-io')
        exclude(module: 'commons-collections')
    }

    /* compile ('org.springframework.integration:spring-integration-core:4.1.2.RELEASE')*/
    compile project(":common")
    testRuntime("org.springframework.boot:spring-boot-starter-web")

}

Any idea what's wrong ?

Thank you.

A couple of options, change:

testRuntime("org.springframework.boot:spring-boot-starter-web")

to:

compile("org.springframework.boot:spring-boot-starter-web")

Also, my Spring Boot build.gradle file does not use the :$project.ext.springBatchVersion variable. It seems to set the variables just fine - for example, here is my (condensed) example build.gradle file.:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.1.RELEASE")
    }
}

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

repositories {
    mavenCentral()
}

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    compile("org.springframework.boot:spring-boot-starter-actuator")
    testCompile("junit:junit")
}

task wrapper(type: Wrapper) {
    gradleVersion = '2.2.1'
}

Answer 2

You either need to provide a version number when you're declaring the dependency or you need to apply the Spring Boot plugin (you've declared the plugin as a build script dependency, but don't appear to have applied it).

When the Spring Boot plugin is applied it'll automatically set the version of spring-boot-starter-web to the same version as the plugin. You can see a list of all the versions that the plugin can set for you in the documentation.
