jboss.server.deploy.dir has been removed in WFCORE-6329. The property was deprecated, jboss.server.content.dir should be used instead, see https://github.com/wildfly/wildfly-core/commit/81d538a86d0ea8da151929ffe7ff5b225a022129#diff-41e4561b0b784d9ea87f5453fe2b243097363bf5e3b17f8c9640b4d85b92d2aaL199

In WildFly there is just one file with jboss.server.deploy.dir: https://github.com/wildfly/wildfly/blob/f112e1931f67805e792f00fa2e670ffc6f61a685/docs/src/main/asciidoc/_admin-guide/management-tasks/Command_line_parameters.adoc#L107, see https://github.com/search?q=repo%3Awildfly%2Fwildfly%20jboss.server.deploy.dir&type=code
