Question

我正在将maven build迁移到gradle，我正在努力在根项目中定义基本的插件配置。并在子模块中提供特定的配置属性。

以下是一个例子：

root：build.gradle

configure(filterSubprojects(['component'])) {

    apply plugin: "org.flywaydb.flyway"

    flyway {
        url = "jdbc:oracle:thin:@${db.host}:${db.port}:${db.name}"
        user = db.owner.name
        password = db.owner.password
    }

}

specific-subproject-component：build.gradle

ext {
    db = [
            host          : <host>,
            port          : <port>,
            name          : <name>,
            user          : [name: <user-name>, password: <user-password>]
    ]
}

我收到了这个错误：

Cannot get property 'db' on extra properties extension as it does not exist

可能是非常基本的问题，但我无法弄清楚如何做到这一点。

这里的问题是，在评估root build.gradle文件时，尚未评估特定组件build.gradle文件，因此当configure块运行时db确实不存在。要解决此问题，您应该能够在root build.gradle文件中声明private boolean spokenTextContainsAnyOfTheCommands(List<String> commands) { for (int i = 0; i < commands.size(); i++) { if (spokenText.contains(commands.get(i))) { currentCommand = commands.get(i); return true; } } return false; } private void handleCommand() { if (youSaidHello) { if (spokenTextContainsAnyOfTheCommands(callCommands)) { int idx = spokenText.indexOf(currentCommand); String whoToCall = spokenText.substring(idx + currentCommand.length()).trim(); callThisDude(whoToCall); } if (spokenTextContainsAnyOfTheCommands(openCommands)) { int idx = spokenText.indexOf(currentCommand); String whatToOpen = spokenText.substring(idx + currentCommand.length()).trim(); Intent appIntent = getAppIntent(whatToOpen); if (appIntent == null) { theTextView.setText(R.string.text_view_after_negative); } else { theTextView.setText(R.string.text_view_after_afirmative); startActivity(appIntent); } } } else { theTextView.setText(R.string.text_view_after_negative); } } private Intent getAppIntent(String appName) { String appPackage = null; PackageManager pm; pm = getPackageManager(); List<ApplicationInfo> appsInfo = pm.getInstalledApplications(0); for (int i = 0; i < appsInfo.size(); i++) { if (appsInfo.get(i).name.toLowerCase().equals(appName.toLowerCase())) { appPackage = appsInfo.get(i).packageName; } } if (appPackage == null) { theTextView.setText(R.string.text_view_after_negative); } else { theTextView.setText(R.string.text_view_after_afirmative); } return pm.getLaunchIntentForPackage(appPackage); }。

Gradle额外属性不存在 - 在子模块
