在 build.properties 中没有找到 key.store 和 key.alias 属性

我正在使用我的Android应用程序进行1步构建。ant-release

我的 build.properties 看起来像这样：

application.package=xxxxx
key.store=sonr
key.alias=sonr labs
key.store.password=xxxx
key.alias.password=xxxx

当我运行ant-release时，除了应用程序签名之外，一切都很好。我收到错误：

-release-prompt-for-password:

-release-nosign:
     [echo] No key.store and key.alias properties found in build.properties.
     [echo] Please sign /Users/syalam/Documents/git/joeborn-sonr/sonr/bin/SONR-release-unsigned.apk manually
     [echo] and run zipalign from the Android SDK tools.
