Synopsis:
$PATH handling buglet
Environment: (jvm, os, osrel, platform)
jdk1.3, Linux, Red Hat Linux 6.1, x86

Additional Environment Description:
This is probably UNIX-specific, and may be a bug in an underlying library. I have a feeling that this is actually a bug in the 1.3 JDK, but didn't track it down far enough to find out. In any case, you might add a note in the documentation to save people the trouble of isolating the problem.

Report Description:
When building a target that needs to execute javadoc (for instance, one including the javadoc element), and there is a directory named 'javadoc' in a directory in your $PATH before the 'javadoc' executable, the following error occurs: Buildfile: ./build.xml init: ##### ${company} ${product} ${version} #### javadoc: [javadoc] Generating Javadoc [javadoc] Javadoc execution BUILD FAILED /home/broz/foo/./build.xml:40: Javadoc failed: java.io.IOException: javadoc: canno\ t execute java.io.IOException: javadoc: cannot execute at java.lang.UNIXProcess.forkAndExec(Native Method) at java.lang.UNIXProcess.(UNIXProcess.java:137) at java.lang.Runtime.execInternal(Native Method) at java.lang.Runtime.exec(Runtime.java:551) at java.lang.reflect.Method.invoke(Native Method) at org.apache.tools.ant.taskdefs.Execute$Java13CommandLauncher.exec(Execut\ e.java:390) at org.apache.tools.ant.taskdefs.Execute.execute(Execute.java:247) at org.apache.tools.ant.taskdefs.Javadoc.execute(Javadoc.java:728) at org.apache.tools.ant.Target.execute(Target.java:142) at org.apache.tools.ant.Project.runTarget(Project.java:818) at org.apache.tools.ant.Project.executeTarget(Project.java:532) at org.apache.tools.ant.Project.executeTargets(Project.java:506) at org..apache.tools.ant.Main.runBuild(Main.java:420) at org.apache.tools.ant.Main.main(Main.java:149) Total time: 1 second I argue that this is a bug, since the shells which I have tried (bash, csh) do not exhibit this behavior (preferring the directory to a file later in the $PATH). It might be worth checking UNIX standards. Email me if you'd like the build files I used to test this; I'll probably want to clean them up a bit. This quite probably affects non-javadoc targets.
