Neatbeans(常见错误) build-impl.xml:305: Compile failed

先贴一段build-impl.xml中javac部分构建失败提所在行的配置

            <sequential>
                <property location="${build.dir}/empty" name="empty.dir"/>
                <mkdir dir="${empty.dir}"/>
                <mkdir dir="@{apgeneratedsrcdir}"/>
                <javac debug="@{debug}" deprecation="${javac.deprecation}" destdir="@{destdir}" encoding="${source.encoding}" excludes="@{excludes}" executable="${platform.javac}" fork="yes" includeantruntime="false" includes="@{includes}" source="${javac.source}" srcdir="@{srcdir}" target="${javac.target}" tempdir="${java.io.tmpdir}">
                    <src>
                        <dirset dir="@{gensrcdir}" erroronmissingdir="false">
                            <include name="*"/>
                        </dirset>
                    </src>
                    <classpath>
                        <path path="@{classpath}"/>
                    </classpath>
                    <compilerarg line="${endorsed.classpath.cmd.line.arg}"/>
                    <compilerarg line="${javac.compilerargs}"/>
                    <compilerarg value="-processorpath"/>
                    <compilerarg path="@{processorpath}:${empty.dir}"/>
                    <compilerarg line="${ap.processors.internal}"/>
                    <compilerarg value="-s"/>
                    <compilerarg path="@{apgeneratedsrcdir}"/>
                    <compilerarg line="${ap.proc.none.internal}"/>
                    <customize/>
                </javac>
            </sequential>

程序本身没有什么错误，但是编译器一构建，就报

F:\项目\subversion\svn2010\jwebplus3\trunk\src\webplus3\webplus3\nbproject\build-impl.xml:868: The following error occurred while executing this line:
F:\项目\subversion\svn2010\jwebplus3\trunk\src\webplus3\webplus3\nbproject\build-impl.xml:305: Compile Failed; see the compiler error output for details.

构建失败 (总时间: 12 秒)

我们来看看305行是什么？

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

其实，我们删除

                    <compilerarg line="${endorsed.classpath.cmd.line.arg}"/>
                    <compilerarg line="${javac.compilerargs}"/>
                    <compilerarg value="-processorpath"/>
                    <compilerarg path="@{processorpath}:${empty.dir}"/>
                    <compilerarg line="${ap.processors.internal}"/>
                    <compilerarg value="-s"/>
                    <compilerarg path="@{apgeneratedsrcdir}"/>
                    <compilerarg line="${ap.proc.none.internal}"/>
                    <customize/>

这段，再次构建，就成功了！
