Fails for me:
Ubuntu Dapper, Ant 1.6.5, Sun JDK 1.5.0_07
<project>
<javac srcdir="." destdir="."/>
</project>
bash:$ ant -v
bash:$ touch test/Test3.java
bash:$ ant -v
[javac] /work/ant-test/ant-generics/test/Test3.java
[javac] /work/ant-test/ant-generics/test/Test3.java:8: incompatible
types
[javac] found : test.Base
[javac] required: test.Sub
[javac] public Sub p() {return this.getV();}
Is this a javac issue rather than ANT issue? I can provide more
information if required.

This works by itself, but touch Test3.java and run again.

Can you enter a bugzilla report about this.
It is very strange.
I tried on the commandline:
javac -target 1.5 -g -source 1.5 -sourcepath src -d build\classes
src\org\test\Test3.java
which works fine - and looks very like the command used by ant.

Hi
For some reason, the mailing server included only the first

}
public Inner3 g() {
return new Inner3(new Sub());

Hi!
I've come accross the following problem trying to
compile Java
5 classes with generics using Ant 1.6.5. I've attached
project with
sample Java classes and a build.xml file.
NOTE: Please create a src/test subdirectory and save the
attached
.java files into it. The mailing list server gave me a hard
time acepting an email with the archived project files. :(
A clean build of the above project works just fine
and compiles
without a problem. If after that, I touch the Test3.java
file the
build fails with the following error:
[javac] C:\src\appforge\test\src\test\Test3.java:5:
incompatible
types
[javac] found : test.Base
[javac] required: test.Sub
[javac] public Sub p() {return this.getV();} [javac]
^ [javac]
1 error
I must admit that this behaviour is really strange. I am
interested
in helping you but the problem is that I didn't receive
any .java
files. Please try to prvide them again.
Initially, I thought that this was a problem with the Java
compiler.
After touching Test3.java, I tried running javac manually:
javac -sourcepath src -d bin -g -source 1.5 -target 1.5
src\test\*.java
It turned out that with the above command-line the project
compiled OK. The project also compiles without a problem
in Eclipse 3.2.1.
Am I missing anything? It is my understanding that the
build file
and the command line should produce the same results.
Upon further experimentation, if I uncomment the method in
Test2.java fixes the problem. Touching Test3.java does
not break the build.
Thanks,
Chavdar
