我正在尝试创建L2j服务器(插曲(服务器。但是，当我尝试编译服务器包文件时，我遇到了麻烦。
当我以 Ant 构建方式运行build.xml时，我得到
编译失败;有关详细信息，请参阅编译器错误输出

50-55 行将是：
<target name="compile" depends="init" description="Compile the source.">
<javac destdir="${build.classes}" optimize="on" debug="on" source="1.8" target="1.8" nowarn="off" includeantruntime="false" deprecation="yes">
<src path="${src}" />
<classpath refid="classpath" />
<compilerarg value="-Xlint" />
</javac>
如果我运行另一个(非常相似(build.xml我得到几乎相同的错误，它会将我定向到不同的行 (89(，因为构建行 88-90 是：
<target name="compile" depends="init" description="Compile the source.">
<javac srcdir="${src}" classpathref="classpath" destdir="${build.classes}" compiler="javac1.8" debug="false" debuglevel="lines,vars,source" includeantruntime="false" source="1.8" target="1.8" />
</target>
我使用的是JDK 1.8.0_171，因为较新的没有工具.jar并且我遇到了无法解决的不同错误(使用此JDK，我能够运行另一个构建(L2j服务器数据包(。
请指教。
以下解决方案对我有用，希望对其他人有所帮助
日食 -> Ant 选项卡 -> 右键单击build.xml->运行方式 ->外部工具配置... -> JRE 选项卡 ->运行时 JRE： -> 选择"在与工作区相同的JRE中运行" -> 应用并运行
