maven - Java 8 import cannot be resolved when executing with CircleCI -


i have java 8 project, built maven. i'm using circleci continuous integration, , following error message during build:

import java.util.function.consumer;        ^^^^^^^^^^^^^^^^^^ import java.util.function cannot resolved

i have:

<source>1.8</source> <target>1.8</target>

in maven-compiler plugin. when run build locally, mvn clean install, or mvn integration-test, executed in circleci, no errors.

is there problem when using circleci java 8 project?

the project source can found here: https://github.com/verjigorm/dragonpunch.git

edit: had @ links suggested below, , fixed build adding:

machine:   java:     version:       oraclejdk8

to circle.yml file.

just because specify want use java 8 in pom file not mean it's going available.

according circle documentation, default oraclejdk7 java runtime. you'll have specify supports java 8, oraclejdk8 instead.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
