cannot find tag library descriptor for spring framework in maven eclipse project
提问by CodeMed
The following three lines at the top of documents.jsp throw "cannot find tag library descriptor for ..." errors in the spring framework application from this tutorial, which uses eclipse and maven:
在本教程使用 eclipse 和 maven的 spring 框架应用程序中，documents.jsp 顶部的以下三行抛出“cannot find tag library descriptor for ...”错误：
<%@ taglib uri="http://www.springframework.org/tags" prefix="spring"%>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
My understanding is that the maven plugin for eclipse should manage the download of these libraries automatically, so I checked to make sure that the following are included in pom.xml:
我的理解是 eclipse 的 maven 插件应该自动管理这些库的下载，所以我检查以确保 pom.xml 中包含以下内容：
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${org.springframework.version}</version>
</dependency>
<properties>
<org.springframework.version>3.0.2.RELEASE</org.springframework.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
So how do I fix my application to enable the required dependencies to be available? I want to avoid having to do it manually, because I was under the impression that maven should manage this. Is there some way that I need to manipulate maven? The application apparently worked when it was tested for the tutorial.
那么如何修复我的应用程序以使所需的依赖项可用？我想避免必须手动执行此操作，因为我的印象是 maven 应该管理此操作。有什么方法可以让我操作 Maven 吗？该应用程序在针对本教程进行测试时显然有效。
EDIT:
编辑：
I converted my eclipse project to a maven project and then right clicked on the eclipse project and chose Maven>Update Project. This did nothing to fix the error that still remains from my original posting above, but it also added the following new error:
我将我的 eclipse 项目转换为 maven 项目，然后右键单击 eclipse 项目并选择 Maven>Update Project。这并没有解决我上面原始帖子中仍然存在的错误，但它也添加了以下新错误：
Missing artifact javax.transaction:jta:jar:1.0.1B
Which is now thrown by the second line of pom.xml, which reads as follows:
现在被 pom.xml 的第二行抛出，内容如下：
<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
SECOND EDIT:
第二次编辑：
When I try to run as..run on server, I get the following error in a dialog box:
当我尝试在服务器上运行 as..run 时，我在对话框中收到以下错误：
'Publishing to Tomcat v7.0 Server at localhost...' has encountered a problem.
Error reading file D:\mypath\.m2\repository\javax\transaction\jta.0.1B\jta-1.0.1B.jar
D:\mypath\.m2\repository\javax\transaction\jta.0.1B\jta-1.0.1B.jar (The system cannot find the file specified)
I even set "update Maven projects on startup" in Window>preferences>Maven and then closed and restarted eclipse, but the problem persists.
我什至在窗口>首选项>Maven中设置“启动时更新Maven项目”，然后关闭并重新启动eclipse，但问题仍然存在。
