Spring Boot项目启动MongoDB报错java.io.IOException: Could not start process

大家好！

本人在用Spring Boot + MongoDB开发一个项目的时候，出现下面这个错误：
java.io.IOException: Could not start process: <EOF>
at de.flapdoodle.embed.mongo.AbstractMongoProcess.onAfterProcessStart(AbstractMongoProcess.java:79)

。。。

看上去是MongoDB没能启动起来。这个报错前面的log是这样的：

这个项目是Gradle的，编译什么的都没有问题。
build.gradle文件如下：

buildscript { // buildscript 代码块中脚本优先执行



	// ext 用于定义动态属性

	ext {

		springBootVersion = '2.0.3.RELEASE'

	}



	// 使用了 Maven 的中央仓库（也可以指定其他仓库）

	repositories {

		//mavenCentral()

		maven { url "https://repo.spring.io/snapshot" }

		maven { url "https://repo.spring.io/milestone" }

		maven { url "http://maven.aliyun.com/nexus/content/groups/public/" }

	}



	// 依赖关系

	dependencies {



		// classpath 声明说明了在执行其余的脚本时，ClassLoader 可以使用这些依赖项

		classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")

	}

}



// 使用插件

apply plugin: 'java'

apply plugin: 'eclipse'

apply plugin: 'org.springframework.boot'

apply plugin: 'io.spring.dependency-management'



// 指定了生成的编译文件的版本，默认是打成了 jar 包

version = '1.0.0'



// 指定编译 .java 文件的 JDK 版本

sourceCompatibility = 1.8



// 使用了 Maven 的中央仓库（也可以指定其他仓库）

repositories {

	//mavenCentral()

	maven { url "https://repo.spring.io/snapshot" }

	maven { url "https://repo.spring.io/milestone" }

	maven { url "http://maven.aliyun.com/nexus/content/groups/public/" }

}



// 依赖关系

dependencies {



	// 该依赖用于编译阶段

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

	

	// 添加 Thymeleaf 的依赖

	compile('org.springframework.boot:spring-boot-starter-thymeleaf')



	// 添加 Spring Data Mongodb 的依赖

	compile('org.springframework.boot:spring-boot-starter-data-mongodb')

	

	// 添加  Embedded MongoDB 的依赖用于测试

	compile('de.flapdoodle.embed:de.flapdoodle.embed.mongo')

	

	// 该依赖用于测试阶段

	testCompile('org.springframework.boot:spring-boot-starter-test')

}

请大家帮忙看下，到底是哪里的问题？谢谢！
