[Scons-users] JDK 1.7 support?

[Peter Steele]

The flatten option removes any intermediate directories in the source tree,
creating a single "flat" result. E.g., if the source tree looked like this:

 

A/

    X1.txt

    B/

        X2.txt

        C/

            X3.txt

 

the target tree would look like this:

 

A/

    X1.txt

    X2.txt

    X3.txt

 

I actually don't know what happens if there are file collisions (e.g., if
A/B/C also contained a file called X1.txt); I've never had a case where this
was an issue.

Peter,

 

Can you describe what "flatten" does?

The env.Command()  suggestion did what I needed. I don't in fact create any
jar files. My ant script has three targets: build, codegen, and copy. I've
been able to reproduce the first two of these and have yet to tackle the
third one. It will be a little tricky since I am using a feature of ant that
doesn't really have a direct parallel in Python, specifically the "flatten"
option of the ant copy task. My ant code looks like this:

 

    <target name="copy">

        <copy todir="${libipc_to.dir}" overwrite="yes" flatten="yes">

            <fileset dir="${ipc_c_from.dir}">

                <include name = "**/**/*.*"/>

                <exclude name = "**/**/*proxy*"/>

                <exclude name = "**/**/*adapter*"/>

            </fileset>

        </copy>    

        <copy todir="${libipc_to.dir}/proxy" overwrite="yes" flatten="yes">

            <fileset dir="${ipc_c_from.dir}">

                <include name = "**/**/*proxy*.*"/>

            </fileset>

        </copy>    

        <copy todir="${libipc_to.dir}/adapter" overwrite="yes"
flatten="yes">

            <fileset dir="${ipc_c_from.dir}">

                <include name = "**/**/*adapter*.*"/>

            </fileset>

        </copy>    

        <copy todir="${javaipc_to_dir}" overwrite="yes">

            <fileset dir="${ipc_java_from.dir}" includes="**/**/*.*">

            </fileset>

        </copy>    

    </target>      

 

To recode these copy tasks into Python will involve a bit of Python coding.

I made this change locally to my JavaCommon.py file and that removed the
"NotImplemented" error. I can submit a fix for this, or raise a bug. I've
never done either before for the scons project. Is there a pointer to the
procedure to follow?

 

I am not taking my ant-to-scons exercise to the next step. After we compile
our sources, we turn around and run the application that was just built. The
ant task we use is this:

 

        <java classname="com.mydomain.MyApp" failonerror="true" fork="yes">

            <jvmarg value="-Darg1=value1"/>

            .

            <jvmarg value="-DargN=valueN"/>

            <classpath refid="my.classpath"/>

        </java>

 

I'm not sure how to represent this in scons. I tried something like this:

 

env = Environment(

    JAVACLASSPATH = [

        .

    ],

    JAVAVERSION = "1.7"

)

 

env.Java("bin", "src")

 

env.Execute("java MyApp .")

 

but this ends up running "MyApp" before the code is compiled. What's the
proper way to convert the "java" Ant target to the equivalent scons command?

 

 

 

Use env.Command(), the source would be the binary, does your MyApp output
any file(s)?

Do you build  a jar?

I'll at least file a bug, but when I get a window in my dev time I'll check
out the source as well. We're considering moving our ant scripts over to
scons and this was the first problem I encountered. Hopefully it will be the
last as well.

I just tried to build our Java project with scons and it complained that JDK
1.7 isn't supported. Is this for real or is this "user error"? My SConscript
looks like this:

 

import os

 

TOT = os.environ["TOT"]

 

env = Environment(

    JAVACLASSPATH = [

        .

    ],

    JAVAVERSION = "1.7"

)

 

env.Java('bin', 'src')

 

The error I got was:

 

NotImplementedError: Java version 1.7 not supported:

 

Please file a bug (or even better a fix) at  <http://scons.tigris.org>
scons.tigris.org. We'll try to get some support in the next release.

 

It may be as simple as just adding the version string into the list of
supported versions which is in the following file:


 
<https://bitbucket.org/scons/scons/history/src/engine/SCons/Tool/JavaCommon.
py> SCons/Tool/JavaCommon.py


 

I believe we actually have a patch in the queue which may resolve this.

You also could try downloading a package from.
