我想用path参数和管道传递文件名。但我失败了,我怎么能做到
mvn exec:java -Dexec.mainClass="edu.princeton.cs.algs4.BinarySearch" \
-Dexec.args="algs4-data/tinyW.txt < algs4-data/tinyT.txt"
使用文件结构时,algs4数据不可见。启动应用程序时,执行的根目录是目标文件夹。通过不将algs4数据放入/src/main/resources这样的src文件夹,它就不会被复制到target/classes中
解决方案应该在不知道代码和测试的情况下在imo中工作:将algs4数据复制到src/main/resources 使用文件结构algs4数据不可见。启动应用程序时,执行的根目录是目标文件夹。通过不将algs4数据放入/src/main/resources这样的src文件夹,它就不会被复制到target/classes中
解决方案应该在不知道代码和测试的情况下在imo中工作:将algs4数据复制到src/main/resources 错误消息是什么?你能发布你的Maven日志吗?错误信息是什么?你能发布你的Maven日志吗?谢谢,我同意你的建议,但是我的构建失败了,我更新了我的问题。algs4 data/tinyW.txt在target/classes中吗?是的(我更新了文件结构),可能是因为我在参数中使用了管道?你能把你的项目放在github上,我可以试着运行它吗?谢谢,我戴上了git@github.com:yu yuxuan/algs4_exercise.git谢谢,我做了你的建议,但是我的构建失败了,我更新了我的问题。algs4 data/tinyW.txt在target/classes中吗?是的(我更新了文件结构),可能是因为我在争论中使用了管道?你能把你的项目放在github上吗?谢谢,我戴上了git@github.com:yu yuxuan/algs4_exercise.git
