Ant 构建中的 Javadoc 任务失败

Question

当我尝试运行 Javadoc ant 任务时，我收到来自 Ant 的错误消息。

"生成失败/data/data/com.termux/files/home/LearnJava/Observer/build.xml：39：没有指定源文件、包和模块。

构建文件位于：

https://github.com/Fernal73/LearnJava/blob/master/Observer/build.properties

分别。

我在存储库上的其他项目也有类似的配置。

它们按预期工作。

我错过了一些明显的东西吗？

我确实错过了一些明显的东西。属性包中有一个额外的"t"。显然，几个小时后，我需要两双眼睛或一双新的眼睛！

现在，我该如何关闭它？

Answer 1

我认为问题出在以下部分：

<fileset dir="${src.dir}">
    <include name="*.java" />
</fileset>

在 Ant 中，"*.java "表示名称与 *.java 匹配的所有文件。这不会在子目录中搜索。要包含所有子目录，您必须指定：

<fileset dir="${src.dir}">
    <include name="**/*.java" />
</fileset>

但是由于您已经指定了 sourcePath 属性，我想知道您是否不能删除文件集元素，因为 ant 默认情况下会添加 **/*.java。
