Eclipse搜索安装Cucumber插件时遇XML无效字符错误求助

环境信息 #

• Eclipse版本：Eclipse IDE for Java Developers（包含孵化组件）2024-12 (4.34.0)
• 触发前提：按要求在pom.xml的properties节点添加以下配置升级JRE到11后（后续需配合Jenkins使用JRE11）

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>11</maven.compiler.source>
<maven.compiler.target>11</maven.compiler.target>

错误现象 #

尝试搜索并安装Cucumber插件时，弹出以下错误：

MarketplaceDiscoveryStrategy failed with an error
Cannot complete request to https://marketplace.eclipse.org/api/p/search/apachesolr_search/cucumber?client=org.eclipse.epp.mpc.core&os=win32&platform.version=4.34: Invalid response content: An invalid XML character (Unicode: 0xde80) was found in the CDATA section.
Invalid response content: An invalid XML character (Unicode: 0xde80) was found in the CDATA section.
An invalid XML character (Unicode: 0xde80) was found in the CDATA section.
Received response begins with:

1:
2:
3:

查看Eclipse错误日志，得到：

org.xml.sax.SAXParseException; lineNumber: 25; columnNumber: 1; An invalid XML character (Unicode: 0xde80) was found in the CDATA section.

已尝试的解决方案 #

• 手动配置网络连接
• 添加代理设置
• 安装相关证书

以上方案均未解决问题，确认该错误并非本地XML文件解析导致，而是Eclipse Marketplace API与搜索功能之间的兼容性问题，寻求技术支持。
