Question

不确定是否是发布此问题的正确位置。（如果不是，抱歉。如果是，请指向正确的方向。）

我正在尝试编译Apache Bahir来生成scala 2.11工件（如mvn clean install -P scala-2.11 -Dscala-2.11 -DskipTests）。尝试这样做时，我遇到了以下构建问题：

在检查common/target目录时，我发现尽管存在一个scala-2.11子目录，其中包含已编译的类文件，但我看不到正在生成适当的bahir-common_2.11-3.0.0-SNAPSHOT*.jar文件（而bahir-common_2.12-3.0.0-SNAPSHOT*.jar似乎生成得很好）。

我想知道这里是否有人可以提供帮助。预先感谢！

我想这是做到这一点的一种方法（？）：

$ cd <project_root_dir>
$ ./dev/change-scala-version.sh 2.11
$ mvn clean package -Pscala-2.11 -Dscala-2.11 -DskipTest

PS：如果有人对此有权威的回答，请鸣叫。谢谢！
