先贴一段build-impl.xml中javac部分构建失败提所在行的配置

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="${javac.compilerargs}"/>
