ANT + JavaDoc

很长时间没有碰Ant，一个小小问题竟然又让我搞上好长一段时间，真是廉颇老矣？

Problem:

build>ant javadoc
Buildfile: build.xml

javadoc:
[javadoc] Generating Javadoc
[javadoc] Javadoc execution

BUILD FAILED
build\build.xml:143: Javadoc failed: java.io.IOException: CreateProcess: C:\j2sdk142\bin\javadoc.exe -d C

PELPM_1\integrati?

Cause: command line is getting to long

Problem Resolved: add attribute useexternalfile="yes" in the javadoc tag.

Good Luck.
