Question

I have a very, very simple any build script:

<project name="quiz_jar" default="all">
<target name="all">
<jar destfile="/home/mike/export/quiz_all.jar" duplicate="preserve">
    <archives>
        <zips>
            <files includes="/home/mike/export/quiz.jar" />
            <files includes="/home/mike/download/jeuclid-3.1.9/repo/*.jar" />
        </zips>
    </archives>
    <manifest>
        <attribute name="Main-Class" value="com.antlersoft.quiz.ui.QuizFrame"/>
    </manifest>
</jar>
</target>
</project>

It works fine when I run it as an Ant task in Eclipse (or from the command line)

However, in the Problems tab, it is marked with the following error:

Default target all does not exist in this
project

Answer 1

I found that if I change any character in the file (like in a path), the error flag goes away. I added a comment to make the error go away. Would still like to know what the problem was.
