In an eclipse maven project using spring web mvc, I am getting the following error in the Markers tab: 

```
Archive for required library: 'D:/mypath/.m2/repository/javax/transaction/jta/1.0.1B/jta-1.0.1B.jar' in project 'DocumentManager' cannot be read or is not a valid ZIP file

```

I have checked, and the jar file is in fact present in the url indicated. I even copied a backup of the jar to overwrite the jar file in that location, but that did not get rid of the error either. I forced maven to update, which did not solve the problem. I also restarted eclipse to no effect.

At one point, jta-1.0.1B.jar had been jta-1.0.1B.jar.LatestUpdate, so I shortened the name to jta-1.0.1B.jar 

In pom.xml, the location of the error message is line 2, which reads as follows: 

```
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">  

```

When I download jta-1.0.1B.jar manually from [this url](http://download.java.net/maven/2/javax/transaction/jta/1.0.1B/), the error in pom.xml goes away but is replaced with new errors in .java class files indicating that 5 methods of the Document class are not valid. 

I read [this](https://stackoverflow.com/questions/19086523/missing-artifact-javax-transactionjtajar1-0-1b-issue-was-different-as-you-m) and [this](https://stackoverflow.com/questions/9003298/missing-javax-transaction-jta-artifact), but I am not using struts, I am already including 3.3.2.ga of hibernate, and I do not have a repository tag in pom.xml (which [this](https://stackoverflow.com/questions/19086523/missing-artifact-javax-transactionjtajar1-0-1b-issue-was-different-as-you-m) said did not even solve the problem anyway), so I do not think this is a duplicate. 

Can anyone suggest a way to fix this problem? If I need a repository tag, where do I put it? And what else do I change to accommodate its addition?

For anyone who is curious, my pom.xml is included for reference as follows:
