这个错误提示表明在连接 Jenkins 节点时出现了问题，可能是由于 SSH 连接配置不正确或者凭据无法找到。可以检查以下几个方面：

1. 确认 Jenkins 节点的 SSH 连接配置是否正确，包括主机名、端口号、用户名等信息。
2. 检查 Jenkins 中的凭据是否被正确配置，并且与节点的连接配置一致。
3. 确认 Jenkins 节点是否已经启动，并且可以通过 SSH 连接进行访问。

如果以上方法无法解决问题，可以尝试查看 Jenkins 的日志文件，以确定问题的具体原因。另外，如果你使用的是 SSH 连接，还需要确保 Jenkins 节点可以正常访问 SSH 服务器，并且你的 SSH 凭据具有访问权限。

Launching a JVM .. JVM exited while loading the application. Unrecognized option:-add-opens java.base/java.Lang=ALL-UNNAMED Error:Could not create the Java virtual Machine. Error:A fatal exception has occurred.Program will exit.

这个错误通常是由于使用了不支持的 JVM 选项导致的。在这里，您使用了一个不被识别的选项 `-add-opens java.base/java.Lang=ALL-UNNAMED`。这个选项可能是针对特定的 Java 版本或特定的 JVM 实现而设计的，而您当前使用的 JVM 不支持它。

要解决这个问题，您可以尝试以下几个步骤：

1. 检查您正在使用的 Java 版本是否支持该选项。您可以尝试升级到最新的 Java 版本，并确保您的应用程序与新版本兼容。

2. 如果您是通过命令行启动 JVM，请检查是否有其他选项或参数与 `-add-opens` 冲突。可能需要移除冲突的选项或参数。

3. 如果您使用的是特定的 JVM 实现（例如 Oracle JDK、OpenJDK、IBM JDK 等），请查看该实现的文档，了解其支持的选项和配置。

如果以上步骤都没有解决问题，您可能需要提供更多的上下文信息，例如您使用的 Java 版本、JVM 实现和启动命令等，以便更好地理解和解决问题。

An internal error occurred during: "Launching 组合". Cannot invoke "java.io.File.getAbsolutePath()" because the return value of "org.eclipse.jdt.internal.launching.LaunchingPlugin.getFileInPlugin(org.eclipse.core.runtime.IPath)" is null

This error message is related to Eclipse and launching a program within the IDE. It indicates that there is an issue with the configuration or setup of the program launch. The error message specifically states that the method "getAbsolutePath()" cannot be invoked because the return value of "getFileInPlugin()" is null, meaning that the file path being referenced cannot be found.

To resolve this error, you can try the following steps:

1. Restart Eclipse and try launching the program again.

2. Check that the program launch configuration is set up correctly, including the file path and other settings.

3. Make sure that all necessary files and resources are included in the project and that they are accessible.

4. If the error persists, try creating a new program launch configuration and see if that resolves the issue.

5. If none of these steps work, try reinstalling Eclipse or resetting the workspace to its default settings.

If you are still unable to resolve the error, you may need to seek further assistance from the Eclipse community or support team.
