maven-clean-plugin/2.5/maven-clean-plugin-2.5.pom: unexpected markup <!d (position: start_document seen \r\n<!d... @2:4) @ line 2, column 4

The error message you're encountering suggests that there is an issue with the formatting or structure of the `maven-clean-plugin-2.5.pom` file. Specifically, the error states "unexpected markup <!d" at the start of the document. This might be caused by a corrupted or incorrectly formatted POM file. Here are a few steps you can try to resolve the issue: 1. Download the `maven-clean-plugin-2.5.pom` file again: It's possible that the file was corrupted during the download process. Try downloading the file again from a reliable source, such as the Maven Central Repository. 2. Check the file encoding: Make sure that the file is saved in the correct encoding (usually UTF-8) and that there are no Byte Order Marks (BOM) at the beginning of the file, which could cause parsing errors. 3. Verify the POM file structure: Open the POM file in a text editor and check that it has the correct structure and syntax. A valid POM file should start with a `<?xml>` declaration followed by a `<project>` element that contains the project metadata. 4. Use a different version of the plugin: If none of the above solutions work, try using a different version of the Maven Clean Plugin. It's possible that the issue is specific to version 2.5 and has been fixed in a later release. If you continue to encounter issues, you may want to seek help from the Maven user community or file a bug report with the plugin maintainers. [2023-12-25 11:12:27 | AI写代码神器 | 313点数解答]
