ant - Apache Ant 和掘金

Question

我一直在尝试在我的PC上使用Nuggeta Server。但是问题是，当我运行build.xml时，它会抛出sym，bol找不到和其他错误，有人可以帮助我吗？

这是ant显示的编译错误:

这是构建文件

<project name="NuggetaGameServer" basedir="." default="jar">
<target name="jar" description="jar">
    <delete file="lib/myServer.jar" />

    <mkdir dir="classes" />
    <echo message="Compiling the java source files..." />
    <javac destdir="classes" debug="on" failonerror="yes" includeantruntime="false">
        <src path="src" />
    </javac>

    <jar destfile="lib/myServer.jar">
        <zipfileset dir="classes/" />
    </jar>
</target>

我已经导入了libs游戏服务器和myServer

您缺少对第3方jars的依赖。一个明显的例子是对SLF4J logging framework的依赖:

Search for org.slf4j.Logger

在所有编程语言中(不仅仅是Java)，管理编译和运行时依赖项都是一个不小的问题。我无权访问您的代码，但您的构建文件似乎不足。

假设您的第3方jars位于“lib”目录中，那么我期望的是:

<project name="NuggetaGameServer" basedir="." default="jar">

  <path id="compile.path">
    <fileset dir="lib"/>
  </path>

  <target name="jar" description="jar">
    <delete file="lib/myServer.jar" />

    <mkdir dir="classes" />
    <echo message="Compiling the java source files..." />
    <javac destdir="classes" debug="on" failonerror="yes" includeantruntime="false" classpathref="compile.path">
        <src path="src" />
    </javac>

    <jar destfile="lib/myServer.jar">
        <zipfileset dir="classes/" />
    </jar>
  </target>

注意javac任务上的“classpathref”属性。这会将“lib”目录中的jar添加到编译时类路径中。
