构建Java项目时出错

Question

I have tryied to build my project in netbeans 6.8/ windows xp, and I've received this errors:

..\nbproject\build-impl.xml:452: The following error occurred while executing this line:

..\nbproject\build-impl.xml:224: Compile failed; see the compiler error output for details.output for details.

The lines are, respectively: 452:

`<j2seproject3:javac gensrcdir="${build.generated.sources.dir}"/>`

224:

<javac debug="@{debug}" deprecation="${javac.deprecation}" destdir="@{destdir}" encoding="${source.encoding}" excludes="@{excludes}" fork="${javac.fork}" includeantruntime="false" includes="@{includes}" source="${javac.source}" sourcepath="@{sourcepath}" srcdir="@{srcdir}" target="${javac.target}" tempdir="${java.io.tmpdir}">

I have tried to reinstall netbeans, java, and anything more...but I can't resolve this error. Do someone know how can I fix it?

All the best!

Answer 1

Sometimes, Netbeans screws up the build file generation
(generation of build-impl.xml from build.xml ).

If may help to remove buid-impl.xml, close project, restart Netbeans, open project. But in some cases Netbeans fails to regenerate this file.

What will help in most cases is:

• Create new project in different location (with same name if you whish);
• Open old and new project;
• Copy all packages from old project, and paste to new project (try with refactoring, but when fails, try without.);
• Adopt manually all project settings from old project into new.
• Forget the old project and delete it ;)

Answer 2

Ok, it's resolved. I haven't seen that one warning was for a library not found. I just give to netbeans that library and my code is compiled well.

Sorry guys Leandro.
