问题：执行wsimport任务时找不到com.sun.tool.ws.ant.WsImport类

我用Spring Initializr创建了新项目，按照官方教程操作时，执行wsimport任务报错，提示找不到com.sun.tool.ws.ant.WsImport类。我的build.gradle配置和教程基本一致，仅添加了部分项目额外依赖，以下是配置文件和错误日志：

解决办法

原因

JAX-WS 3.0（适配Jakarta EE 9+）版本中，WsImport的Ant任务类路径和类名发生了变更，原com.sun.tool.ws.ant.WsImport类已不存在，且当前配置缺少专门的Ant任务依赖。

修复步骤

修改Ant任务类名
将taskdef中的classname改为com.sun.xml.ws.ant.WsImport：

taskdef(
    name: 'wsimport',
    classname: 'com.sun.xml.ws.ant.WsImport',
    classpath: configurations.jaxws.asPath
)

添加Ant任务依赖
在jaxws依赖块中加入专门的Ant任务包：

jaxws 'com.sun.xml.ws:jaxws-ant:3.0.0',
    'com.sun.xml.ws:jaxws-tools:3.0.0',
    'jakarta.xml.ws:jakarta.xml.ws-api:3.0.0',
    'jakarta.xml.bind:jakarta.xml.bind-api:3.0.0',
    'jakarta.activation:jakarta.activation-api:2.0.0',
    'com.sun.xml.ws:jaxws-rt:3.0.0'

移除重复依赖
删除buildscript中的jaxws-tools依赖，避免类加载冲突：

// 删掉这段代码
buildscript {
    dependencies {
        classpath 'com.sun.xml.ws:jaxws-tools:3.0.0'
    }
 }

清理缓存重新构建
执行命令清理缓存并重新构建：
```
./gradlew clean build --refresh-dependencies
```
