Unity3d 两个几乎相同的批处理脚本之一出现语法错误：“）&引用；无法在此按语法处理

我正在尝试为自动Unity构建设置Jenkins服务器

因此，我写了两个（在我看来）基本相同的批处理脚本

Jenkins使用

执行Windows批处理命令

步骤作为构建步骤运行这两个脚本

命令：

E:\unityiimport.bat

然后，第二个

执行Windows批处理命令

步骤使用

命令：

E:\unityBuild.bat

它们都有相同的开始，因为我需要收集一些文件路径，特别是项目的unity版本。因此，在这两个脚本中，我使用完全相同的方法对项目版本进行解析和字符串拆分。它们之间唯一不同的是，第一个启动Unity并将一个专用的

unitypackage

（保存下一步要执行的方法）导入到项目中，而第二个启动Unity以执行实际构建（不幸的是，它一次也没用……Unity似乎在导入

unitypackage

之前尝试执行该方法）

但是，第二个脚本总是失败，并出现语法错误

此处无法按语法处理“”

我想要达到的是

读取文件

%WORKSPACE%\ProjectSettings\ProjectVersion.txt的内容

SET /p TEST=<%WORKSPACE%\ProjectSettings\ProjectVersion.txt

和

ECHO。ProjectVersion.txt=%TEST%

看起来像

ProjectVersion.txt = m_EditorVersion: 2019.3.4f1

字符串拆分，以便仅获取包含版本号的最后一部分

for %%x in (%TEST::= %) do (
    SET "VALUE=%%x"
    SET "UNITY_VERSION=!VALUE:~0,-2!" 
)

因此

%UNITY\u VERSION%

通常包含例如

2019.3.4

。我没有更多的拆分，因为还有两位数的Unity版本，例如

2018.4.18

在

上拆分字符串，以便仅获取主要版本号

for /f "tokens=1,2 delims=." %%a in ("%UNITY_VERSION%") do (
    SET "A=%%a"
    SET "B=%%b"
)
SET "UNITY_VERSION=%A%.%B%"

这导致

%UNITY\u VERSION%

成为例如

2019.3

最后，如果存在所需版本，则搜索所有已安装的Unity版本

set "UNITY_FOLDER="
for /f "delims=" %%a in ('dir /b E:\Unity\%UNITY_VERSION%*') do (
    set "UNITY_FOLDER=%%a"
)

在此之后，我们找到了给定版本的有效Unity安装文件夹，或者没有

---

下面是脚本

导入（如预期那样工作）

我认为剩下的不重要，因为正如我在控制台中看到的，它在例如

ProjectVersion.txt=2019.3.4f1

此处无法按语法处理“”

是否有人看到了错误，或者Jenkins是否有什么原因导致第二个脚本因语法错误而失败，即使我认为它们基本相同？

代码中存在多个小问题，我在下面对批处理文件的建议中逐一解释了这些问题

根据文件

ProjectVersion.txt

中定义的

UNITY\u版本

获取

UNITY\u文件夹

的任务可以通过使用以下代码更高效地完成：

@echo off
setlocal EnableExtensions DisableDelayedExpansion

if not defined WORKSPACE (
    echo ERROR: Environment variable WORKSPACE is not defined.
    exit /B 1
)

if not exist "%WORKSPACE%\ProjectSettings\ProjectVersion.txt" (
    echo ERROR: File "%WORKSPACE%\ProjectSettings\ProjectVersion.txt" does not exist.
    exit /B 1
)

set "UNITY_FOLDER="
set "UNITY_VERSION="
for /F "usebackq tokens=2-4 delims=. " %%I in ("%WORKSPACE%\ProjectSettings\ProjectVersion.txt") do (
    if not "%%~K" == "" (
        for /F "delims=abcdef" %%L in ("%%~K") do (
            set "UNITY_VERSION=%%~I.%%~J.%%~L"
            for /D %%M in ("E:\Unity\%%~I.%%~J*") do set "UNITY_FOLDER=%%M"
        )
    )
)

if not defined UNITY_VERSION (
    echo ERROR: Failed to determine unity version from "%WORKSPACE%\ProjectSettings\ProjectVersion.txt".
    exit /B 1
)
if not defined UNITY_FOLDER (
    echo ERROR: Failed to find a folder in "E:\Unity" for unity version %UNITY_VERSION%.
    exit /B 1
)

echo Found for unity version %UNITY_VERSION% the folder "%UNITY_FOLDER%".

cd /D "%WORKSPACE%" 2>nul
if errorlevel 1 (
    echo ERROR: Failed to set "%WORKSPACE%" as current folder.
    exit /B
)
rem Other commands to execute.

endlocal

setlocal EnableExtensions EnableDelayedExpansion
set "TEST=m_EditorVersion: 2019.3.4f1"
for %%x in (%TEST::= %) do (
    SET "VALUE=%%x"
    SET "UNITY_VERSION=!VALUE:~0,-2!" 
)
endlocal

此批处理文件首先使用命令SETLOCAL设置此批处理文件所需的执行环境

接下来通过批处理文件验证环境变量

WORKSPACE

是否存在。此环境变量应由Jenkins在此批处理文件之外定义。缺少此重要环境变量的定义时输出错误消息

然后通过打印错误消息（如果不存在）和退出批处理文件（退出代码为1）检查文本文件是否存在

如果在批处理文件之外偶然定义，则删除两个环境变量

UNITY\u FOLDER

和

UNITY\u VERSION

接下来将处理文本文件，该文件应仅包含一个包含感兴趣数据的非空行。否则，在执行其他命令之前，如果第一个子字符串等于

m_EditorVersion:

，则有必要更改代码以同时计算第一个子字符串

FOR带有选项

/F

默认情况下将

“

中包含的集合解释为要处理的字符串。但在这种情况下，

“

中的字符串应解释为文件的完全限定文件名，该文件的内容应逐行处理。因此，选项

usebackq

用于获取所需的文件内容处理行为

FOR在处理文件内容时始终忽略空行。因此，文本文件顶部是否包含一行或多行空行并不重要

FOR默认情况下使用普通空格和水平制表符作为字符串分隔符将行拆分为子字符串。如果第一个空格/制表符分隔的字符串在删除所有前导空格/制表符后以分号作为默认的行尾字符开头，则该行也会被忽略，就像空行一样。最后，仅将第一个空格/制表符分隔的字符串分配给指定的循环变量

I

此处不需要此默认行处理行为，因为仅将

m_EditorVersion:

分配给指定的循环变量

I

是不够的。因此，选项

delims=。

用于将线拆分为点和空格。选项

tokens=2-4

通知FOR第二个空格/点分隔的子字符串

2019

应分配给循环变量

I

，第三个空格/点分隔的子字符串

3

到下一个循环变量

J

，它是中的下一个字符，第四个空格/点分隔的子字符串

4f1

到下一个循环变量

K

由于spac的原因，在选项参数字符串的末尾指定

delims=。

并将空格字符作为最后一个字符是很重要的
