Question

我尝试在Spring Boot App上启动ProGuard并收到错误消息：

  [proguard] Reading library jar [C:\Program Files\Java\jdk1.8.0_151\jre\lib\rt.jar]
     [proguard] Note: duplicate definition of library class [javax.annotation.Generated]

为什么会出现此错误以及如何解决？

您可以执行以下操作来摆脱这种情况：

如果添加了proguard选项-printconfiguration configuration.txt，您将看到所有proguard添加的内容。
根据您从以上步骤中获得的信息，您可以更正相同的内容

OR

您可以使用以下选项停止查看这些警告消息：文档here

-dontwarn javax.annotation.*
-dontnote javax.annotation.*

Answer 2

尝试忽略类public function writePage() { if(!$this->header){ $this->SetHeaderMargin(0); } else{ $this->SetHeaderMargin(5); } if(!$this->footer){ $this->SetFooterMargin(0); } else{ $this->SetFooterMargin(21); } $this->setMargins(10, 40, 10); $this->AddPage(); $this->writeHTML($this->content, true, false, true, false, ''); }
