在自己電腦上的jenkins，有一段時間沒有登錄，jenkins 登錄提示無效
<useSecurity>true</useSecurity> 修改成false
<authorizationStrategy class="hudson.security.FullControlOnceLoggedInAuthorizationStrategy">
<denyAnonymousReadAccess>true</denyAnonymousReadAccess>
</authorizationStrategy>
<securityRealm class="hudson.security.HudsonPrivateSecurityRealm">
<disableSignup>true</disableSignup>
<enableCaptcha>false</enableCaptcha>
</securityRealm>
刪除 </authorizationStrategy>和</securityRealm> ，重啟jenkins，重新打開jenkins即可
