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

【 tulaoshi.com - 编程语言 】

先贴一段build-impl.xml中javac部分构建失败提所在行的配置
代码如下：

            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
                    SPAN style="COLOR: #ff0000"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//SPAN
                /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subversionsvn2010jwebplus3trunksrcwebplus3webplus3nbprojectbuild-impl.xml:868: The following error occurred while executing this line:
F:项目subversionsvn2010jwebplus3trunksrcwebplus3webplus3nbprojectbuild-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
代码如下：

SPAN style="COLOR: #ff0000"                    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//SPAN

这段，再次构建，就成功了！
