使用 waf 构建 Java 项目

Question

我使用this 演示代码创建了一个构建我的java 项目的wscript。现在，我希望在与创建类文件的目录不同的输出目录中创建一个 jar 文件。

当我尝试添加这一行时：

jaropts = '-C default/src/ .', # can be used to give files

蟒蛇说：

AttributeError: 'str' object has no attribute 'append'

是否甚至可以使用 waf 为单个文件指定多个输出路径，并且 jaropts 是配置它的正确位置吗？

Answer 1

从the source 来看，jaropts 应该是一个参数列表，而不是一个字符串。

试试jaropts = ['-C', 'default/src/', '.']
