android - 无法为 'dialog' 创建组件，原因 : java. awt.HeadlessException

Question

将 gradle 更新到版本 3.0.0-beta3 后，当我尝试显示一个对话框以询问 key 的密码时出现此错误。

我尝试添加 System.setProperty('java.awt.headless', 'false') 但它没有用，我在谷歌上没有发现任何新东西......

Error:(20, 1) Failed to create component for 'dialog' reason: java.awt.HeadlessException

java.awt.HeadlessException (no error message)

import groovy.swing.SwingBuilder

gradle.taskGraph.whenReady { taskGraph ->
        def storePassword = ''
        def keyPassword = ''
        if (System.console() == null) {
            new SwingBuilder().edt {
                dialog(modal: true, title: 'Enter password', alwaysOnTop: true, resizable: false, locationRelativeTo: null, pack: true, show: true) {
                    vbox {
                        label(text: "Please enter store passphrase:")
                        def input1 = passwordField()
                        label(text: "Please enter key passphrase:")
                        def input2 = passwordField()
                        button(defaultButton: true, text: 'OK', actionPerformed: {
                            storePassword = input1.password;
                            keyPassword = input2.password;
                            dispose();
                        })
                    }
                }
            }
        } else {
            storePassword = System.console().readPassword("\nPlease enter store passphrase: ")
            keyPassword = System.console().readPassword("\nPlease enter key passphrase: ")
        }

        if (storePassword.size() <= 0 || keyPassword.size() <= 0) {
            throw new InvalidUserDataException("You must enter the passwords to proceed.")
        }

        storePassword = new String(storePassword)
        keyPassword = new String(keyPassword)

        android.signingConfigs.Keys.storePassword = storePassword
        android.signingConfigs.Keys.keyPassword = keyPassword
}

只需在 import groovy.swing.SwingBuilder 之前添加 System.setProperty('java.awt.headless', 'false') 并使用 终止 gradle deamon ./gradlew --stop

它给你一些类似的东西:

apply plugin: 'com.android.application'

System.setProperty('java.awt.headless', 'false')

import groovy.swing.SwingBuilder
