无法解析以下工件:javax.sql:jdbc-stdext:jar:2.0，javax.transaction:jta

Question

我在使用 Maven 构建应用程序时收到以下错误。

无法解析以下工件：javax.sql：jdbc-stdext：jar：2.0，javax.transaction：jta：jar：1.0.1B：无法找到javax.sql：jdbc-stdext：jar：2.0 https://repo.maven.apache.org/maven2 缓存在本地存储库中，在 central 的更新间隔过去或强制更新之前，不会重新尝试解析 -> [帮助 1]

我尝试在pom.xml中包含javax.sql:jdbc-stdext。但它也不起作用

pom.xml ：

我希望它能成功运行。但显示错误。

你能指出我做错了什么吗？我是Maven的新手。提前谢谢。

Answer 1

尝试为 mysql 连接器添加依赖项：

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.16</version>
        </dependency>

此依赖项用作jcs:jcs:1.3的传递依赖项

Answer 2

将 jcs 依赖项更改为以下内容，它起作用了。

<dependency>
  <groupId>org.apache.jcs</groupId>
  <artifactId>jcs</artifactId>
  <version>1.3</version>
</dependency>

还增加了对javax.servlet的依赖
