Question

当我查看https://github.com/alexeyr/scala-time并使用Maven构建一次时，一切正常。然后我触摸src / main / scala / org / scala_tools / time / Implicits.scala来触发重新编译。再次运行mvn compile，我得到56个类似于

的错误

[ERROR] F:\MyProgramming\scala-time\src\main\scala\org\scala_tools\time\StaticDateTime.scala:29: error: value second is not a member of Int
[ERROR]   def nextSecond = now + 1.second

似乎没有看到触摸文件中定义的含义并使用import org.scala_tools.time.Implicits._导入。但与此同时，没有错误object Implicits is not a member of package org.scala_tools.time，正如我希望在这种情况下看到的那样。

在mvn clean之后，可以再次编译一次而不会出错。

有人可以重现吗？
如果是，我该如何解决？

更新：它也发生在SBT上，但只有Implicits.scala实际上已经足够改变以产生不同的类文件（例如添加一行object Implicits2 extends Implicits）。错误集是不同的！

Answer 1

不满意修复：rm -rf target; mvn compile - rampion 9小时前

无用修复，因为他可以mvn clean compile - 这将是跨平台的解决方案：）

Answer 2

我可以在没有maven的情况下重新创建错误，因此看起来这可能与scalac的使用方式（或scalac的错误）有关：

% rm -rf target
% mkdir -p target/classes
% cat scalac-args | sed "s;~;$HOME;g" | xargs scalac-2.9 # runs successfully
% cat scalac-args | sed "s;~;$HOME;g" | xargs scalac-2.9
#...
56 errors found

（sed命令只解析.m2中的scalac-args目录

scalac-args

的位置

已经下载了正确的罐子。

如果我在target/classes参数中将target/classes/org/scala_tools/time/替换为-classpath，那么它可以正常工作。

% rm -rf target
% mkdir -p target/classes
% cat scalac-args | sed "s;~;$HOME;g" | xargs scalac-2.9 # runs successfully
% cat scalac-args | sed "s;~;$HOME;g" | xargs scalac-2.9 # runs successfully

因此，当路径上有一个目录时，maven-scala-plugin期望scalac期望scalac查看包相应的子目录，但{{1}}没有这样做。我不确定谁错了。

Scala Maven重新编译中的错误，无需更改代码
