I&#39;ve noticed, that starting from version 0.9.6 maven support stopped wo=
rking. The last version, I&#39;m able to use with maven projects is ensime_=
2.9.2-RC1-0.9.3.RC4.<br>
By &quot;stopped working&quot; I mean following:<br>
When I try to start ensime for the new project, it correctly detects, that =
it is a maven project, and proceeds with creating an .ensime file. When I r=
un it with M-x ensime afterwards, it starts in seconds (which is cool, of c=
ourse), but seems to be only compiling the source file, opened in current b=
uffer. It also won&#39;t see project&#39;s classpath.<br>





Is this a known issue? Will maven support be reenabled in the future?<br>
