Stephen Connolly updated MNG-6401:
----------------------------------
Fix Version/s: (was: 3.6.0-candidate)
3.6.x-candidate
> Cannot interpolate property in proxy port of settings.xml
> ---------------------------------------------------------
>
> Key: MNG-6401
> URL: https://issues.apache.org/jira/browse/MNG-6401
> Project: Maven
> Issue Type: Bug
> Components: Bootstrap & Build
> Affects Versions: 3.0, 3.5.3
> Reporter: KATADA Junya
> Priority: Minor
> Fix For: 3.6.x-candidate
>
>
> If you use a property in proxy port of settings.xml, the property is not replaced and the port number is "0" instead of property value.
> My minimal demo about this problem is [here|https://github.com/jkatada/maven-property-demo].
> In my demo, export two environment variables as follows.
> {code}
> export MAVEN_PROXY_HOST_STRING=proxy.foo.com
> export MAVEN_PROXY_PORT_INT=18080
> {code}
> These variables are used in settings.xml for proxy settings.
> {code:xml}
> <proxy>
> <id>my_proxy</id>
> <active>true</active>
> <protocol>http</protocol>
> <host>${env.MAVEN_PROXY_HOST_STRING}</host>
> <port>${env.MAVEN_PROXY_PORT_INT}</port>
> <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
> </proxy>
> {code}
> Execute maven-help-plugin to show effective settings.xml.
> {code}
> mvn help:effective-settings -X
> {code}
> The result is as follows.
> {code:xml}
> <proxy>
> <port>0</port>
> <host>proxy.foo.com</host>
> <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
> <id>my_proxy</id>
> </proxy>
> {code}
> `*${env.MAVEN_PROXY_HOST_STRING}*` is replaced with `*proxy.foo.com*`,
> but `*${env.MAVEN_PROXY_PORT_INT}*` is not replaced with `*18080*`.
> I found the following WARNING message in console.
> {code:java}
> [WARNING] Some problems were encountered while building the effective settings
> [WARNING] Unable to parse element 'port', must be an integer (position: END_TAG seen ...<port>${env.MAVEN_PROXY_PORT_INT}</port>... @12:47) caused by: java.lang.NumberFormatException: For input string: "${env.MAVEN_PROXY_PORT_INT}" @ /root/.m2/settings.xml, line 12, column 47
> {code}
> I think that the cause of this problem is to parse settings.xml before interpolation.
