Exception in thread "main" java.lang.UnsatisfiedLinkError: Failed to find the library mclmcrrt7_17.dll, required by MATLAB Builder JA, on java.library.path. This library is typically installed along with MATLAB or the MCR, its absence may indicate an issue with that installation or the current path configuration. The MCR version that this component is trying to use is: 7.17.

这个错误通常是因为您的Java程序无法找到所需的mclmcrrt7_17.dll库文件。这个库文件通常是与MATLAB或MCR一起安装的，它可能没有正确安装或在当前的路径配置中找不到。您可以尝试以下几个步骤来解决这个问题：

1. 确保您已经安装了MATLAB或者MCR，并且版本号与您的程序所需要的版本号相符。

2. 确认您的系统环境变量中是否设置了MATLAB或者MCR的路径，如果没有，请将其添加到系统环境变量中。

3. 检查您的Java程序是否正确设置了java.library.path系统属性，以便能够找到所需的库文件。您可以尝试在程序中设置该属性：

System.setProperty("java.library.path", "path/to/mclmcrrt7_17.dll");

确保将“path/to/mclmcrrt7_17.dll”替换为实际的文件路径。

4. 如果您仍然无法解决问题，您可以尝试重新安装MATLAB或者MCR，并确保在安装过程中选择正确的选项。如果您是在64位系统上运行Java程序，则需要安装64位版本的MATLAB或者MCR。

希望这些方法能够帮助您解决问题。

Exception in thread "main" java.lang.UnsatisfiedLinkError: Failed to find the required library mclmcrrt9_9.dll on java.library.path.

这是一个错误信息，意味着你的 Java 应用程序无法找到所需的 mclmcrrt9_9.dll 库文件。通常情况下，这是由于缺少或损坏的库文件引起的。你需要确保该库文件存在于正确的位置，并且它的版本与你的应用程序所需的版本匹配。你还可以尝试将该库文件的路径添加到 java.library.path 环境变量中，以便 Java 应用程序可以找到它。如果这些方法都无效，你可以搜索并下载该库文件，然后将其手动添加到你的应用程序中。

Handler dispatch failed; nested exception is java.lang.UnsatisfiedLinkError: Failed to find the required library mclmcrrt9_4.dll on java.library.path. This library is typically installed along with MATLAB or the MATLAB Runtime. Its absence may indicate an issue with that installation or the current path configuration, or a mismatch with the architecture of the Java interpreter on the path. MATLAB Runtime version this component is attempting to use: 9.4. Java interpreter architecture: win64.

This error message indicates that the Java interpreter is unable to find the mclmcrrt9_4.dll library, which is required by MATLAB or the MATLAB Runtime.

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

1. Check that MATLAB or the MATLAB Runtime is installed on your system. If it is not installed, you will need to install it to use the library.

2. Check that the path to the directory containing the mclmcrrt9_4.dll library is included in your java.library.path system variable. You can check this by opening a terminal or command prompt and running the following command:

   echo %java.library.path%

If the path to the directory containing the library is not included in the output, you will need to add it to the java.library.path variable. You can do this by adding the following line to your system environment variables:

   java.library.path=<path to directory containing mclmcrrt9_4.dll>

3. Check that the Java interpreter architecture matches the architecture of the mclmcrrt9_4.dll library. In this case, the error message indicates that the Java interpreter architecture is win64. You will need to ensure that the mclmcrrt9_4.dll library is also the 64-bit version that matches the architecture of the Java interpreter.
