如何在groovy中打印色彩控制台

Question

我已经创建了GroovyAnsi.groovy文件，代码如下: Source现在是https://gist.github.com/tvinke/db4d21dfdbdae49e6f92dcf1ca6120de，请帮助我在jenkins groovy脚本中调用此函数来为输出着色。

我不能使用这个函数，因为我得到下面的错误: groovy.lang.MissingPropertyException:没有这样的属性: out for class: groovy.lang.Binding at groovy.lang.Binding.getVariable(Binding.java:63) at org.jenkinsci.plugins.scriptsecurity.sandbox.groovy.SandboxInterceptor.onGetProperty(SandboxInterceptor.java:270)

您必须向Jenkins类路径提供您的类Ansi。您可以使用Ansi类创建一个jar，并将该jar复制到Jenkins类路径中，或者必须在Jenkins中使用的每个groovy脚本中声明Ansi类。
