在build.gradle内设置从local.properties读取的属性

我使用的是3.4级。我已将以下属性移动到名为local.properties的文件中（与build.gradle目录相同）：

local.properties

nexusUsername=someuser
nexusPassword=somepassword

build.gradle

File secretPropsFile = file('./local.properties')
if (secretPropsFile.exists()) {
    Properties p = new Properties()
    p.load(new FileInputStream(secretPropsFile))
    p.each { name, value ->
       project.set name, value
    }
} else {
    throw new IllegalStateException("secret.properties could not be located for build process")
}

我得到以下例外情况：

Could not find method set() for arguments [nexusUsername, someuser] on root project 'some-java-project of type org.gradle.api.Project.

您得到的错误是正确的。要设置属性，需要使用

ext

。请看一下这本书

因此，以下代码将完成这项工作：

File secretPropsFile = file('./local.properties')
if (secretPropsFile.exists()) {
    Properties p = new Properties()
    p.load(new FileInputStream(secretPropsFile))
    p.each { name, value ->
        ext[name] = value
    }
} else {
    throw new IllegalStateException("secret.properties could not be located for build process")
}

println project.nexusPassword
println project.nexusUsername //property is set in project's scope via ext
