Java NetBeans 6.9.1构建和ant目标即使构建成功也会给出错误消息

我有一个NetBeans 6.9.1项目，选中了NetBeans项目目录选项中存储的库。我的项目中还安装了一些ant构建脚本

现在，当我运行任何ant目标（包括可能最简单的目标，如clean）时，或者当我从IDE构建项目时，我在output窗口中的构建过程结束时获得以下输出

我不知道如何摆脱这些错误。我曾尝试重新创建该项目，因为我在网上看到netbeans 6.5.1。有一个损坏build-impl.xml文件的问题，但这并没有解决我的问题。重要的是构建确实成功了，但是如果在构建结束时没有看到这些错误，并且每次都必须在输出窗口中向上滚动以确保构建工作正常（或者如果我搞砸了一个文件或其他东西，就失败了），那就太好了

提前谢谢你的帮助

如果部署，忽略这些消息或将

ant

输出级别更改为正常

如果没有，请检查

GlassFish

选项卡上的输出。

Hmm，很有趣-我不是Netbeans用户，但看起来Netbeans在幕后使用常春藤来解决依赖关系。您是否可以在Netbeans中访问internet（例如，您是否启用了代理）？是的，Netbeans可以访问internet，但我不确定为什么必须这样做。我最近才开始注意到这一点，大约在我让我的项目在项目文件夹中存储库的时候。此外，我尝试挂载netbeans拥有的所有库（Ant等），但这并没有使消息消失。
