Question

我目前正在尝试为不再为美国服务的旧mmo获取私人服务器。我绝不是一个Java高手，但是我一直在谷歌上搜索并且在墙上撞了几个小时而没有运气。我为此使用了eclipse，安装了JDK和JRE并配置了路径。

build.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<project name="L1J" default="all" basedir=".">

        </manifest>
    </jar>
</target>

<!-- clean Target -->
<target name="clean2">
    <delete dir="${build.dir}" />
</target>

</project>

运行Build.xml后Eclipse的输出：

Buildfile: C:\Users\Administrator\workspace\L1J\build.xml

BUILD FAILED
C:\Users\Administrator\workspace\L1J\build.xml:28: C:\Users\Administrator\workspace\L1J\libs does not exist.

Total time: 390 milliseconds

我确实尝试手动创建目录，这样做允许脚本运行，但是这给了我一个＆＃34;无法找到或加载主类jp.l1j.server＆＃34;使用此启动服务器批处理文件运行时出错：

@java -server -XX:MetaspaceSize=256m -XX:MaxMetaspaceSize=256m -Xms1024m -Xmx1024m -XX:NewRatio=2 -XX:SurvivorRatio=8  -jar l1jserver
@pause

非常感谢任何帮助！

Answer 1

您是否需要任何第三方库来编译或运行您的应用程序？您的类路径似乎总是空的，因为您必须手动创建libs目录。我认为在构建jar时你不需要任何依赖，因为ant build成功了，但是你可能需要在运行时使用它们吗？

Answer 2

fileset嵌套在具有id libs的path内，一旦pathconvert任务执行，就会扫描目录库。由于pathconvert超出任何target，因此会在任何target之前执行。

此外，无论如何，我都看不到mkdir lib.dir。

Ant构建失败了mkdir
