无法为'对话'原因创建组件：java.awt.HeadlessException [英] Failed to create component for 'dialog' reason: java.awt.HeadlessException

问题描述

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

After updating gradle to version 3.0.0-beta3 I have this error when I try to display a dialog box to ask for the password of the key.

我尝试添加 System.setProperty（'java.awt.headless'，'false'），但它没有工作，我发现没有什么新的谷歌....

I tried to add System.setProperty('java.awt.headless', 'false') but it did not work and I found nothing very new on google ....

                            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
}

推荐答案

只需添加 System.setProperty（'java。 awt.headless'，'false'）在之前导入groovy.swing.SwingBuilder 并用 ./ gradlew杀死gradle deamon - 停止

它给你一些东西：

apply plugin: 'com.android.application'

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

import groovy.swing.SwingBuilder
