Description Mark Struberg 2012-07-25 11:42:53 UTC
Currently tomcat7 can only be build with jdk1.7. That might become a problem as Servlet-3.0 mandatory requires java6 as environment.

You are wrong. 1). It is true that Tomcat trunk (aka Tomcat 8) builds only with jdk1.7. It is as intended. It is expected to implement the Servlet 3.1 specification. 2). Tomcat 7 builds with jdk1.6 and this status quo has not changed. Anyway your report noticeably lack of details. You should ask on the mailing list first, before playing around with Bugzilla.

I thought I would step through the latest trunk BUILDING.TXT instructions because I haven't updated my sandbox for at least a month. Apache Ant(TM) version 1.8.2 compiled on December 3 2011 Trying the default build file: build.xml Buildfile: /home/brian/sandboxApache/tomcat8/trunk/build.xml Detected Java version: 1.6 in: /usr/lib/jvm/java-6-sun-18.104.22.168/jre Detected OS: Linux compile: [javac] Compiling 307 source files to /home/brian/sandboxApache/tomcat8/trunk/output/classes [javac] javac: invalid target release: 1.7 [javac] Usage: javac <options> <source files> [javac] use -help for a list of possible options BUILD FAILED I wondered whether it is still necessary to tell people how to get a JDK... if they haven't got one already, and aren't familiar with building complex projects, they probably shouldn't be encouraged to start building tomcat from the trunk! In the end, I thought the best compromise would be to just reference a couple of popular JDKs - we don't want to seem partisan, but equally don't want to get dragged into a debate about which is "best". It might be helpful to list the JDKs that are used to build and test the production releases, but I don't know what they are. I will attach a patch for a trivial change, which will hopefully avoid this kind of confusion in future!

trunk != 7.0.x/trunk hence closing this as INVALID. Maybe we need to start an 8.0.x BZ project for 8.0.x specific issues. I have updated the building instructions for trunk and also included a reference to OpenJDK and other JDK vendors although on this occasion I did not use the provided patch.
