这里有一个类似的问题：Gradle properties not being read from ~/.gradle/gradle.properties但它并没有解决我的问题。
在我看来，Gradle没有读取我的~/.gradle/gradle.properties文件。
I have a gradle.properties file in ~/.gradle , and it has properties needed to sign artifacts before uploading to maven central. It looks like this:

signing.keyId=12345678
signing.password=myPassword
signing.secretKeyRingFile=/home/me/.gnupg/secring.gpg

sonatypeUsername=me
sonatypePassword=myOtherPassword

当我尝试构建我的项目时，它会抱怨没有sonatypeUsername属性，因此：

> Could not find property 'sonatypeUsername' on root project 'yourProject'.

以下是我的项目的build.gradle的相关部分：

uploadArchives {
    repositories {
        mavenDeployer {

            // lots of non-interesting things here

            repository(url: "https://oss.sonatype.org/service/local/staging/deploy/maven2/") {
                authentication(userName: project.property("sonatypeUsername"), password: project.property("sonatypePassword"))
            }
        }
    }
}

当我尝试使用调试功能构建项目时，我看到了以下有关属性的内容：

$ ./gradlew --stacktrace --debug build
