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密钥的密码时出现此错误.
我试图添加System.setProperty(‘java.awt.headless’,’false’),但它没有用,我发现谷歌上没有什么新东西….
Error:(20,1) Failed to create component for ‘dialog’ reason:
java.awt.HeadlessExceptionjava.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 }
解决方法
只需在导入groovy.swing.SwingBuilder之前添加System.setProperty(‘java.awt.headless’,’false’)并使用./gradlew -stop杀死gradle deamon
它给你的东西：
apply plugin: 'com.android.application'
System.setProperty('java.awt.headless','false')
import groovy.swing.SwingBuilder
