使用waf构建Java项目

Question

我已经使用this演示代码创建了一个构建java项目的wscript。现在，我希望在一个不同的输出目录中创建一个jar文件，而不是在其中创建类文件的那个目录。

当我尝试添加这一行时：

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

python说：

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

是否有可能使用waf为单个文件指定多个输出路径，而jaropts是配置该路径的正确位置吗？

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/', '.']
