对于我们应用程序的卸载程序,我需要从我们的一个JAR文件中获取一个版本。所以我使用以下选项创建了ExtractZipFileAction

Property mode: 644
Property destinationDirectory: .
Property destinationRoot: Installation directory
Property dirMode: 755
Property fileFilter: 
Property showProgress: false
Property zipFile: OurJarFile-1.0-SNAPSHOT-plugin.jar
Property zipRoot: Installation directory
Property rollbackSupported: true

但执行会立即取消ClassCastException(错误日志中的堆栈跟踪):

[ERROR] com.install4j.runtime.beans.actions.files.ExtractZipFileAction [ID 541]: java.lang.ClassCastException: com.install4j.runtime.installer.helper.comm.impl.UninstallerHelperContextImpl cannot be cast to com.install4j.api.context.InstallerContext

请注意,我们在卸载程序中,而不是安装程序,但异常抱怨将UninstallerHelperContextImpl转换为InstallerContext。这可能是JAR文件的问题吗?

我还将动作提升类型设置为Elevate to maximum available privileges,因为我想提取程序文件夹中安装目录中的文件。
