.war files containing duplicate entries will cause wait for user input before proceeding

[cobrin]

I found the scanner hung when processing a .war file that contained duplicate .jar files, this causes the unzip to hang waiting for user confirmation e.g.

  inflating: /tmp/log4j_for_extract/WEB-INF/lib/commons-dbcp-1.4.jar
  inflating: /tmp/log4j_for_extract/WEB-INF/lib/commons-digester-1.8.jar
replace /tmp/log4j_for_extract/WEB-INF/lib/log4j-api-2.16.0.jar? [y]es, [n]o, [A]ll, [N]one, [r]ename: ^C

[08:53|root@gbjhccy01:/opt/vconsole/lib]# unzip -tv webui.war | grep log4j-api-2.16.0.jar
    testing: WEB-INF/lib/log4j-api-2.16.0.jar   OK
    testing: WEB-INF/lib/log4j-api-2.16.0.jar   OK
[08:53|root@host:/opt/vconsole/lib]#

My solution
