After some investigation, I would like to re-phrase my question. Here are my
files:
main/build.xml containing a target invoking a target in sub directory
<target name="test-sub">
<echo message="main base dir=${basedir}" />
<ant dir="./sub" inheritall="false" target="MyTest"/>
<subant target="MyTest" genericantfile="sub/build.xml">
<dirset dir="." includes="sub" />
</subant>
</target>
main/sub/build.xml --> containing a target "MyTest" running a JUnit test --
calling A.B.C.MyTest class
<echo message="sub base dir=${basedir}" />
<target name="MyTest">
<junit>
<classpath refid="project.classpath" />
<formatter type="brief" usefile="false" />
<test name="A.B.C.MyTest" />
</junit>
</target>
Inside MyTest.java, I added this print out:
final String currentDir = new File(".").getAbsolutePath();
System.out.println("currentDir=" + currentDir);
Running the target MyTest at main/sub is *fine*, with these printout:
[echo] sub base dir=/xxx/xx/main/sub
MyTest:
[junit] currentDir=/xxx/xx/main/sub/. <------The printout in MyTest
shows that it is run at main/sub, so inside MyTest, a relative path is
correct
Running the target test-sub at main is *bad*, with these printout:
test-sub:
[echo] main base dir=/xxx/xx/main
[echo] sub base dir=/xxx/xx/main/sub/. <--- the echo from sub/build.xml
shows that the base dir is already main/sub, not main/, however, MyTest is
still run at main/, not main/sub
MyTest:
[junit] currentDir=/xxx/xx/main/. <------The printout in MyTest shows
that it is still be run at main/, not main/sub, so inside MyTest, a relative
path becomes invalid
Thank you very much.
