如何阻止 JBehave 修剪多行参数？

Question

我有一个步骤需要检查某些消息。我使用了多行参数：

Then I see welcome message: 'Welcome to our site! 
Some more text 
Even more text'

问题是消息应该在第一行和第二行的末尾有空格（IDK 为什么，但它应该）。 JBehave 会修剪每一行的空格。所以测试失败了。

如何设置不修整这个参数？

我试过写 \n 代替实际的换行符，但它没有被换行符取代

还尝试在参数的开头添加 {trim=false}，但它会将其作为参数的一部分读取。

用引号做了一些实验（使用了“，'，无），它也没有帮助......

我已经测试过了，似乎 JBehave 实际上在测试结束时截断了空格：

When some step with multitline parameter:first line has 10 spaces at the end          
Second line has 6 spaces at the end      
Third line has no spaces at the end, but fourth line has 8 spaces

Fifth line has 3 spaces, and Sixth line has only 7 spaces

    @When("some step with multitline parameter:$lines")
    public void stepWithMultilneString(String s) {

        String lines [] = s.split("\\r?\\n");

        for(int i = 0; i < lines.length; i++) {
            System.out.format("Line %d is: >>%s<<\n", i+1, lines[i]);
        }
    }

Line 1 is: >>first line has 10 spaces at the end          <<
Line 2 is: >>Second line has 6 spaces at the end      <<
Line 3 is: >>Third line has no spaces at the end, but fourth line has 8 spaces<<
Line 4 is: >>        <<
Line 5 is: >>Fifth line has 3 spaces, and Sixth line has only 7 spaces<<

我建议绕过——在文本的开头和结尾使用分隔符! 的步骤：

When step with multitline parameter surrounded by !:!first line has 10 spaces at the end          
Second line has 6 spaces at the end      
Third line has no spaces at the end, but fourth line has 8 spaces

Fifth line has 3 spaces, and Sixth line has only 7 spaces

    @When("step with multitline parameter surrounded by !:$string")
    public void stepWithMultilneStringVersion2(String s) {

        if( s.startsWith("!")) {
            s = s.substring(1);
        }
        if( s.endsWith("!")) {
            s = s.substring(0, s.length()-1);
        }

        String lines [] = s.split("\\r?\\n");

        for(int i = 0; i < lines.length; i++) {
            System.out.format("Line %d is: >>%s<<\n", i+1, lines[i]);
        }
    }
