taglib uri="http://tiles.apache.org/tags-tiles" 出现错误

Question

我在 pom.xml 中添加了 tile 依赖项。

当我添加这一行时，我的 jsp 页面上出现错误

现在当我运行 mvn eclipse:eclipse 时，它​​只下载 pom 文件而不是 jar 文件请参见下面的图片 image-1 和 image-2。这就是我收到错误的原因，请参阅 img-3

Answer 1

在 maven central (http://search.maven.org/#search|gav|1|g%3A%22org.apache.tiles%22%20AND%20a%3A%22tiles-api%22) 上查看，我在 2.2 版本中找不到tiles-api。

实际上，所有瓦片依赖项都是如此。

尝试改为使用 2.2.0（或 2.2.1 或 2.2.2）：

<properties>
    ...
    <tiles.version>2.2.0</tiles.version>
</properties>

Answer 2

我看不到你的整个 JSP 代码，但是除了上面的答案，还要确保你在这个 jsp 中引用的所有页面都有

<%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles"%>

在页面顶部，否则将无法加载。
