在 Jenkins Scripted Pipeline 中使用 WORKSPACE 驱动器

Question

这似乎是直截了当的要求，我需要为 Jenkins 提取驱动器，以便构建剩余路径。 在 JenkinsFile.xml 中，我有以下内容

def drive = "${WORKSPACE}".substring(0, 1) // This saves drive as "C" as expected
echo "set MYVAR=${drive}" // this gets replaced and prints set MYVAR =C
withEnv([ ' MYVAR =${drive}']) { // However, this does expands to MYVAR =C as expected
        bat ' set MYVAR =${drive}' // This gets execute as set MYVAR =${drive}
        // Expected is set MYVAR =C
    }

我也试过了

withEnv([ ' MYVAR ="${drive}"']) { // However, this does expands to MYVAR =C as expected
withEnv([ ' MYVAR ="drive"']) { // However, this does expands to MYVAR =C as expected

我错过了什么？

修复是更新脚本：

withEnv([ ' MYVAR =' + drive]) {
        bat ' set MYVAR =' +drive 
    }
