Question

获取错误：

syntax error near unexpected token `elif' 
`elif [ "$PROJECT_DIR" = "Automation" ] then'

我在Textpad ++中保存了Unix行格式，所以我不确定问题是什么......

#!/bin/bash

....

if [ "$PROJECT_DIR" = "Utility" ] then

    echo "$PROJECT_DIR: Compiling..."
    javac -sourcepath $SOURCE -classpath $CLASSPATH -d $OUTPUT $SOURCE/*.java -deprecation

    echo "$PROJECT_DIR: Compiling..."
    javac -sourcepath $SOURCE -classpath $CLASSPATH -d $OUTPUT $SOURCE/*.java -deprecation

elif [ "$PROJECT_DIR" = "Automation" ] then

    echo "$PROJECT_NAME: Compiling..."
    javac -sourcepath $SOURCE -classpath $CLASSPATH -d $OUTPUT $SOURCE/*.java

elif [ "$PROJECT_DIR" = "Sync" ] then

    echo "$PROJECT_DIR: Compiling..."
    javac -sourcepath $SOURCE -classpath $CLASSPATH -d $OUTPUT $SOURCE/*.java -deprecation 
    echo "$PROJECT_DIR: Compiling..."
    javac -sourcepath $SOURCE -classpath $CLASSPATH -d $OUTPUT $SOURCE/*.java -deprecation 
    echo "$PROJECT_DIR: Compiling..."
    javac -sourcepath $SOURCE -classpath $CLASSPATH -d $OUTPUT $SOURCE/*.java -deprecation 

fi

Answer 1

问题是您需要在]和then之间使用分号（或换行符）。

[不是shell语法的一部分。它是一个内置命令，相当于test命令（除了[需要]作为其最后一个参数，而test不是{0}}

（另一方面，关键字if，then，elif和fi以及分号是部分shell的语法。）

所以如果你写：

if [ "$PROJECT_DIR" = "Utility" ] then

单词then只是[命令的另一个参数。

将每次] then更改为] ; then都可以解决问题。

Answer 2

尝试这样做（删除大部分代码行以保持答案简短）。不需要上次elif条件elif [ "$PROJECT_DIR" = "Sync" ]。它应该只是else部分，如下所示。

if [ "$PROJECT_DIR" = "Utility" ] 
then
    echo "$PROJECT_DIR: Compiling..."    
elif [ "$PROJECT_DIR" = "Automation" ] 
then
    echo "$PROJECT_NAME: Compiling..."    
else 
    echo "$PROJECT_DIR: Compiling..."
fi

Unix elif语法错误
