I've downloaded mondrian v.3.5.10 source files from github.
I followed all instructions and used ant build scripts provided in distribution to build mondrian.war.
However, when I launched tespage.jsp to view pivot table I encountered this error:
Apache documentation claims that this method (isTraceEnabled) is available sinece log4j version 1.2.12:
Also, ivy.xml claims that log4j depencency required version is 1.2.14:
However, when I launched ant war command from mondrian distribution root folder (which also contains build.xml and ivy.xml), the mondrian.war archive that was build contained log4j-1.2.8 version.
<dependency org="log4j" name="log4j" rev="1.2.14"/>
Probably, there is something wrong with the build script. I've made a quick research and, unfortunatelly, haven't found anything suspicious.
