注意:Java/Closure Compiler 的实际错误来自--js- out putfilet中的缺失!

我有这个 PowerShell 脚本:

cls
$jsFiles = @();

Get-ChildItem | Where {$_.PsIsContainer} | Foreach {
    $dir = $_.FullName;
    $jsFile = $dir + "\" + $_.Name + ".js";
    if (Test-Path ($jsFile)) {
        $jsFiles += $jsFile;
    }
}

$wd = [System.IO.Directory]::GetCurrentDirectory();

# Build Closure Compiler command line call
$cmd = @("-jar $wd\..\ClosureCompiler\compiler.jar");

Foreach ($file in $jsFiles) {
    # Both insert a newline!

    $cmd += "--js $file";
    #$cmd = "$cmd --js $file";
}


$cmd = "$cmd --js_ouput_file $wd\all.js";

Invoke-Expression "java.exe $cmd"

问题是每个+=$cmd = "$cmd str"调用都插入了换行符!

Echoargs 给了我这个输出:

Arg 0 is <-jar>
Arg 1 is <S:\ome\Path\compiler.jar>
Arg 2 is <--js>
Arg 3 is <S:\ome\Path\script1.js>
Arg 4 is <--js>
Arg 5 is <S:\ome\Path\script2.js>
...
Arg 98 is <--js_ouput_file>
Arg 99 is <S:\ome\Path\all.js>

(可能)因此,我收到一些错误java.exe

java.exe : "--js_ouput_file" is not a valid option
At line:1 char:1
+ java.exe -jar ...

尝试重写为更简单的版本:

cls

$wd = [System.IO.Directory]::GetCurrentDirectory();

# Build Closure Compiler command line call
$cmd = "-jar $wd\..\ClosureCompiler\compiler.jar";

$arrayOfJs = Get-ChildItem -Recurse -Include "*.js" | % { "--js $_.FullName" };

$cmd += [string]::Join(" ", $arrayOfJs);

Invoke-Expression "java $cmd --js_ouput_file $wd\all.js"

当你这样做

$cmd = @(...);

您正在创建一个数组,因此+=它的后续操作是将元素附加到数组而不是字符串连接。只需将其作为字符串,或在使用 $cmd 之前。执行以下操作:

$cmd -join " "

这会将元素连接在一起,形成一个以空格分隔的字符串。默认情况下,当数组被强制转换为字符串时,您将在元素之间看到新行。
