Maven资源复制失败：There are no more files错误求助

问题现象 #

执行mvn clean build时触发错误，后续运行mvn resources:resources也会报同样的错。近期未修改代码，仅将杀毒软件从Avast更换为Windows Defender。项目resources目录下有3036个.txt和.properties格式文件，每次报错的目标文件不固定，即使删除大部分资源文件仅保留1003个，构建仍失败。

解决方案 #

从错误栈看，根源是Windows系统下File.getCanonicalPath()调用原生方法时抛出的文件访问异常，结合杀毒软件更换的背景，按以下步骤排查解决：

1. 排查Windows Defender拦截 #

• 临时关闭Windows Defender实时保护，重新执行构建，确认是否是杀毒软件在扫描过程中锁定了资源文件
• 如果关闭后构建正常，将项目根目录添加到Windows Defender的排除项：
  打开Windows安全中心 → 病毒和威胁防护 → 管理设置 → 添加或删除排除项 → 选择项目所在文件夹

2. 升级Maven资源插件 #

当前使用的maven-resources-plugin 2.7版本较旧，存在文件处理相关bug，升级到最新稳定版（如3.3.1）：
在pom.xml的<plugins>节点中添加：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.3.1</version>
</plugin>

3. 优化资源处理配置 #

• 检查资源目录中是否存在路径过长（超过Windows默认260字符）或带特殊字符的文件，如有则重命名或调整目录结构缩短路径
• 如果不需要对资源文件做变量替换，禁用资源过滤：
  修改pom.xml中的<resource>配置，添加<filtering>false</filtering>：

<resource>
    <directory>src/main/resources</directory>
    <filtering>false</filtering>
</resource>
<resource>
    <directory>src/main/java</directory>
    <includes>
        <include>com/AAA/microwave/XXX/about.properties</include>
    </includes>
    <filtering>false</filtering>
</resource>

4. 调整Maven JVM参数 #

在系统环境变量中添加MAVEN_OPTS，设置：

-Dsun.io.useCanonCaches=false

该参数会禁用文件路径缓存，避免因缓存导致的文件访问冲突
