Gradle多模块项目无法找到模块依赖项

我正在尝试用Intellij构建一个简单的java项目,它有许多模块。

我有以下项目结构: project_structure

我的根项目 build.gradle :

group 'com.wat'
version '1.0-SNAPSHOT'

apply plugin: 'java'

sourceCompatibility = 1.8
repositories {
    mavenCentral()
}
dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.12'
}

我的根项目 settings.gradle :

rootProject.name = 'Foot'
include 'app'
include 'model'

和我的应用程序模块 建筑格拉德尔 :

group 'com.wat'
version '1.0-SNAPSHOT'

apply plugin: 'java'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.12'
    compile project ':model'
}

Error:(14, 0) Could not get unknown property ':model' for DefaultProjectDependency{dependencyProject='project ':app'', configuration='default'} of type org.gradle.api.internal.artifacts.dependencies.DefaultProjectDependency.
<a href="openFile:C:\Users\lukas\IdeaProjects\Foot\app\build.gradle">Open File</a>

我在寻找类似的问题,但他们的解决方案都不能解决我的问题。

当我离开的时候

dependencies {
testCompile group: 'junit', name: 'junit', version: '4.12'
compile project ':model'
}

在每个模块中 建筑格拉德尔

我得到以下错误:

Error:(2, 0) Gradle DSL method not found: 'testCompile()'
Possible causes:<ul><li>The project 'Foot' may be using a version of the Android Gradle plug-in that does not contain the method (e.g. 'testCompile' was added in 1.1.0).
