java.lang.StackOverflowError 在使用 emailext 插件时

Question

在我的管道结束时，我想发送一封邮件来查看我的构建是否成功。因此，我使用以下 groovy 脚本：

emailext (
to: 'mail@example.com',
subject: 'Job: ' + env.JOB_NAME + ' / ' +'Build #' + env.BUILD_NUMBER + ' / ' + ' Summary',
body:'Integrity Checkout: '+ '\t\t\t' + checkoutStatus +'\n\n' + 'Build1: '+ '\t\t\t' + Build1 + '\n' 
                                                       + 'Build2 :'+ '\t' + Build2 + '\n'
                                                       + 'Build3 :'+ '\t' + Build3 + '\n'
                                                       + 'Build4 :'+ '\t' + Build4 + '\n'
                                                       + 'Build5 :'+ '\t' + Build5 + '\n'
                                                       + 'Build6 :'+ '\t' + Build6 + '\n'
                                                       + 'Build7 :'+ '\t' + Build7 + '\n'
                                                       + 'Build8 :'+ '\t' + Build8 + '\n'
                                                       + 'Build9 :'+ '\t' + Build9 + '\n'
                                                       + 'Build10:'+ '\t' + Build10 + '\n'
                                                       + 'Build11:'+ '\t' + Build11 + '\n'
                                                       + 'Build12:'+ '\t' + Build12 + '\n'
                                                       + 'Build13:'+ '\t' + Build13 + '\n'
                                                       + 'Build14:'+ '\t' + Build14 + '\n'
                                                       + 'Build15:'+ '\t' + Build15 + '\n'
                                                       + 'Build16:'+ '\t' + Build16,
attachLog: true,
compressLog: true
)

基本上代码可以工作，但前提是我注释掉最后一行 (build16)。变量已正确分配。但是如果我执行代码，我会得到 java.lang.WhosebugError。（超过 1000 行）

Answer 1

问题解决了。大量的“+”运算符导致了溢出。现在我正在使用 java.lang.StringBuilder 和 .append 来构建我的输出字符串。
