当依赖项不可用时 Gradle 构建失败

Question

build.gradle（省略不必要的部分）：

apply plugin: 'java'

repositories {
    mavenCentral()
    maven {
        credentials {
            username "$mavenUser"
            password "$mavenPassword"
        }
        url "http://localhost:8081/nexus/content/groups/public"
    }
}

dependencies {
    compile("com.example:some-lib:1.0.0-RELEASE")
}

假设配置的 Maven 存储库中缺少定义的依赖项。 ./gradlew clean build 任务执行后，应用程序构建成功，尽管缺少所需的依赖项。

有没有办法配置 Gradle 在存在未解决的依赖项时失败？

Answer 1

考虑这个build.gradle（注意：故意在dependencies中指定的伪造jar）：

apply plugin: 'java'

repositories {
    mavenCentral()
}

dependencies {
    compile("junit:junit:4.12")
    compile("junit:junitxyz:51.50")
}

task checkDependencies() {
    doLast {
        configurations.compile.each { file ->
            println "TRACER checking: " + file.name
            assert file.exists() 
        }
    }
}

compileJava.dependsOn checkDependencies

示例输出：

$ gradle -q clean compileJava

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':checkDependencies'.
> Could not resolve all files for configuration ':compile'.
   > Could not find junit:junitxyz:51.50.
     Searched in the following locations:
       - https://repo.maven.apache.org/maven2/junit/junitxyz/51.50/junitxyz-51.50.pom
