我的Checkstyle配置似乎无法找到我的suppressions.xml，但它确实存在，并且它正在使用的文件路径有效。 我的checkstyle.xml和suppressions.xml都在config/checkstyle中。我的checkstyle.xml包含以下内容：
<module name="SuppressionFilter">
<property name="file" value="${config_loc}\suppressions.xml"/>
<property name="optional" value="false"/>
</module>
当我运行
gradlew check --stacktrace命令时，堆栈跟踪显示如下：Caused by: com.puppycrawl.tools.checkstyle.api.CheckstyleException: Unable to find: C:\Users\ntroncoso\Online Drive\projects\test-project\test-project-sdk\config\checkstyle\suppressions.xml

正如我之前提到的，我可以将该文件路径复制并粘贴到文件浏览器中打开。我也尝试过直接硬编码完整路径，但是我遇到了同样的错误。唯一让我想到的可能问题就是 \ntroncoso 部分。有些系统会将其视为路径中的换行符。但通常，该错误信息也会打印出换行符，所以我不认为这是问题所在。
