宣布了JSTL 1.2版，但从Maven存储库交付了1.1版

问题描述

我正在寻找一种简单的方法来从Maven存储库中获取JSTL 1.2实现JAR，这听起来很简单，但实际上却很困难.

I'm looking for an easy way to fetch a JSTL 1.2 implementation JAR from a Maven repository, which sounds quite easy but in fact proves to be quite difficult.

我尝试了以下软件包:

javax.servlet : jstl : 1.2
通过 http://repo1.maven.org/maven2/javax/servlet/jstl/1.2/jstl-1.2.jar

javax.servlet.jsp.jstl : jstl : 1.2
通过 http://download.java. net/maven/1/javax.servlet.jsp.jstl/jars/jstl-1.2.jar

这两个工件都应包含JSTL 1.2实现.但是，当我下载JAR并在其中一个JAR(其内容相同)中打开文件/META-INF/c.tld时，标题显示:

Both these artifacts should contain the JSTL 1.2 implementation. However, when I download the JARs and open the file /META-INF/c.tld within one of these JARs (their content is the same), the header shows:

<taglib xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-jsptaglibrary_2_1.xsd"
    version="2.1">

  <description>JSTL 1.1 core library</description>
  <display-name>JSTL core</display-name>
  <tlib-version>1.1</tlib-version>
  <short-name>c</short-name>
  <uri>http://java.sun.com/jsp/jstl/core</uri>
  ...

这意味着该标记不是1.2而是1.1.为了进行比较，当我直接从 http://download.java.net/maven/glassfish/org/glassfish/web/jstl-impl/1.2/jstl-impl-1.2.jar c.tld文件看起来正确:

This means that the tag isn't a 1.2 but a 1.1 tag. For comparison, when I download the JAR file directly from http://download.java.net/maven/glassfish/org/glassfish/web/jstl-impl/1.2/jstl-impl-1.2.jar the c.tld file looks correct:

  ...
  <description>JSTL 1.2 core library</description>
  <display-name>JSTL core</display-name>
  <tlib-version>1.2</tlib-version>
  <short-name>c</short-name>
  <uri>http://java.sun.com/jsp/jstl/core</uri>
  ...

所以，问题是:为什么Maven存储库中包含错误版本(1.1而不是1.2)的JAR(或更具体地说是tld声明)，我如何通过Maven获取正确的JSTL版本?

So, the question is: Why do the Maven repositories contain the JARs (or more specifically the tld declaration) for the wrong version (1.1 instead of 1.2) and how can I fetch the correct JSTL version via Maven?

推荐答案

1. 在 https://issues.sonatype.org/browse/MVNCENTRAL

作为短期解决方案，将本地.m2存储库中的JAR文件替换为来自java.net的正确JAR.

As a short term fix, replace the JAR file in your local .m2 repo with the correct JAR from java.net.

如果您使用代理，也请在其中替换.

If you use a proxy, replace it there as well.
