我在尝试构建项目时得到NullPointerException
。我目前在顶层声明我的依赖关系为properties
,然后在子模块中引用(如下所示):
错误:
A problem occurred evaluating project ':myProject'.
> java.lang.NullPointerException (no error message)

顶级声明:
ext.libraries = [
junit: 'junit:junit:4.12',
mockito: 'org.mockito:mockito-all:1.9.5'
]
引用子模块中的属性:
testCompile([
libraries.junit,
libraries.mockito
])
我在子模块的testCompile([
行收到错误。可能导致这种情况的原因是什么?
答案 0 :(得分:1)
以下脚本适用于gradle 2.8:
apply plugin: 'java'
ext.libraries = [
junit: 'junit:junit:4.12',
mockito: 'org.mockito:mockito-all:1.9.5'
]
repositories {
mavenCentral()
}
dependencies {
testCompile(
[
libraries.junit,
libraries.mockito
]
)
}
在这里查看demo。
