JavaFx -发现意外的令牌LPAREN

Question

我有一个JavaFx项目。其他一切似乎都没问题，除了css，我有一些类得到错误高亮显示，例如:

.min_max_close {
    -fx-padding: 0 12 0 12;
    -fx-border-width: 0 0 0 0;
    -dean-lightnavy: derive(navy, 100%);
    -dean-navygrad: linear (0%,0%) to (100%,0%) stops (0%, -dean-lightnavy) **(**100%, navy);
    -fx-background-color: linear (0%,0%) to (0%,50%) stops (0%, derive(deepskyblue, 80%)) **(**30%, deepskyblue) reflect;
    -fx-effect: dropshadow(three-pass-box, gray, 32, 0.5, 0, 0);
    -fx-background-image: url("../MediaTools/Ports/16/clearsearch.png");
    -fx-background-repeat: no-repeat;
    -fx-background-size: 16 16;
    -fx-background-position: center center;
    -fx-effect: dropshadow(three-pass-box, derive(gray, 50%) 32, 0.5, 0, 0);
}
.win_min {
    -fx-padding: 0 12 0 12;
    -fx-border-width: 0 0 0 0;
    -dean-lightnavy: derive(navy, 100%);
    -dean-navygrad: linear (0%,0%) to (100%,0%) stops (0%, -dean-lightnavy) **(**100%, navy);
    -fx-background-color: linear (0%,0%) to (0%,50%) stops (0%, derive(deepskyblue, 80%)) **(**30%, deepskyblue) reflect;
    -fx-effect: dropshadow(three-pass-box, gray, 32, 0.5, 0, 0);
    -fx-background-image: url("../MediaTools/Ports/Tiny/shevron_l.png");
    -fx-background-repeat: no-repeat;
    -fx-background-size: 10 7;
    -fx-background-position: center center;
    -fx-effect: dropshadow(three-pass-box, derive(gray, 50%) 32, 0.5, 0, 0);
}

上面粗体部分会出现红色的错误高亮显示:

Unexpected token LPAREN found
----
(Alt-Enter shows hints)

在这些区域:

**(**100%, navy) -> the (
**(**30%, deepskyblue) -> the (

项目编译完美，但我只是好奇如何解决这个问题，最重要的是，如果这可能会让我在未来遇到麻烦。谢谢大家。

看起来你正在使用旧的渐变语法(这是无效的css!)请使用新的语法，如http://docs.oracle.com/javafx/2/api/javafx/scene/doc-files/cssref.html

所述。你的渐变看起来像:

-dean-navygrad: linear-gradient(from 0% 0% to 100% 0%, -dean-lightnavy 0%, navy 100%)
-fx-background-color: linear-gradient(from 0% 0% to 0% 50%, reflect, derive(deepskyblue, 80%) 0%, deepskyblue, 30%);
