Common Failures in Maven Project Source Code Porting

JAR parsing exception

The dependency package contains files with sensitive names.

Decompress the JAR package and check whether the package includes a file whose file name contains a character string ./, ../, ../../, or ... If any such a file is found, delete the invalid character string or rename the file.

The package size has exceeded the upper limit.

1. Check the package size.
   • On Windows: Go to the JAR package directory and run the dir JAR_package_name command.
   • On Linux: Go to the JAR package directory and run the ll command.
2. Modify the global.properties file in the config directory of the devkit-migration-plugin-x.x.x-jar-with-dependencies.jar package in the resources directory to increase the upper limit specified by the jar_size_limit field.

The number of files in the package exceeds the upper limit.

Modify the global.properties file in the config directory of the devkit-migration-plugin-x.x.x-jar-with-dependencies.jar package in the resources directory to increase the upper limit specified by the jar_file_num_limit field.

• If a sub-module is depended on, you can run the mvn clean install command in the sub-module directory to install the sub-module to the local repository.
• If another JAR package is required, upload it to the remote repository or run the following command to install it in the local repository:

  1	mvn install:install-file -Dfile=/path/to/ruoyi-common.jar -DgroupId=com.ruo -DartifactId=ruoyi-common -Dversion=4.7.9 -Dpackaging=jar
