JDK_IMPORT_PATH

[David Herron]

I just fclone'd the JDK7 source tree and am running through the build 
process.

I'm running into a build failure if ALT_JDK_IMPORT_PATH is not set.  
This variable is not discussed in README-builds.html but is mentioned in 
jdk/make/README.

The build failure is the same as here:
http://www.mail-archive.com/build-dev@openjdk.java.net/msg00273.html
It gets a short way into the build and dies while compiling idlj.  In 
the followup discussion Kelly wrote that this variable shouldn't need to 
be set.  I did download the matching binary plug and 
ALT_BINARY_PLUGS_PATH is set to where that's unpacked.  ALT_BOOTDIR is 
set to my Java6 install.

This message
http://www.mail-archive.com/build-dev@openjdk.java.net/msg00275.html
suggests a possible fix but I tried that and it made no difference.

I downloaded the full JDK7 bundle, unpacked it, set ALT_JDK_IMPORT_PATH 
to it, and now the build is going.  But I think this shouldn't be 
necessary --- In

It's said this variable is used for importing stuff during a partial 
build.  But in this case I'm at the root of a full  forest and typing 
"make all".
