Question

我在这里问一个其他人已经问过的问题，但我找到的每个答案都没有解决我的问题。

我目前正在使用struts2和maven以及jetty-maven-plugin，但是eclipse会丢失有关JSPs个文件的错误，说它无法找到{{1}文件。

另外，当我启动jetty：run命令时，它会说：

/struts-tag.tld

和pom

[ERROR] Number of foreign imports: 1
[ERROR] import: Entry[import  from realm ClassRealm[maven.api, parent: null]]

有谁知道如何修复它？因为什么都没有用。

我发现了问题。

你只需要在struts中将log4j api添加到相同版本的log4j中。对我来说是

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
    <version>2.8.1</version>
</dependency>

希望它会帮助别人！
