Prior to DITA-OT 3.5, subcommands were specified with the double-hyphen option syntax,
which is still supported for backwards compatibility. (For example, dita
--install will still work.)

+ Certain commands, for example, the dita install command, use a
+ network connection for installing and downloading content. In environments where an HTTP proxy
+ is used to establish a network connection, provide the proxy configuration via the
+ ANT_OPTS environment variable.

+ To configure the proxy for a specific session, from the command prompt, issue the
+ following command:
+
+
+ Platform
+ Command
+
+
+ Linux or macOS
+ export ANT_OPTS="-Dhttp.proxySet=true \
+ -Dhttps.proxyHost=<HTTPS proxy IP address> \
+ -Dhttp.proxyHost=<HTTP proxy IP address> \
+ -Dhttp.proxyPort=<HTTP proxy port> \
+ -Dhttps.proxyPort=<HTTPS proxy port>"

+ -Dhttp.proxyHost=<HTTP proxy IP address> \
+ -Dhttp.proxyPort=<HTTP proxy port> \
+ -Dhttps.proxyPort=<HTTPS proxy port>
+
+
+
+
+ To persistently change the value, change the value allocated to the
+ ANT_OPTS environment variable on your system.
+
+
+ If a command has previously failed due to a connection timeout, issue the command
+ again. For
+ example:dita install <plug-in>
