我有一个包含Java源代码的源文件夹。这些Java文件有不同的包。使用javac命令,我可以生成包结构,但是这些包将包含类文件而不是源文件。
是否有任何API可以从Java文件生成包结构并将Java文件放入特定的包中?

package=$(grep -h -m 1 package "$file" | sed -e 's/.*package[[:space:]]\+\(.*\)[[:space:]]*;.*/\1/' -e 's/\./\//g')
。这将一次性完成所有操作。 - Philipp Wendler这是我为这个问题想到的解决方案。它打开Java文件,读取包名称,生成结构并将文件复制到该结构中。欢迎提出改进意见。 :)
