Bash 导出并在脚本中使用带引号和空格的变量

Question

I'm trying to pass many jvm parameters to one variable and export it and call in other script, but space nad double quotes in parameter beat me. ("/05 abcdef")

My code:

#!/bin/bash
NORMAL_VARIABLE=-DNORMAL.NormalText=normal124
PROBLEMATIC_VARIABLE='-DPROBLEM.ProblematicText="/05 abcdef"'
SUM="$NORMAL_VARIABLE $PROBLEMATIC_VARIABLE"
export SUM

Target script:

java $SUM -jar "ApacheJMeter.jar" "$@"

Actual output in debug mode:

+ NORMAL_VARIABLE=-DNORMAL.NormalText=normal124
+ PROBLEMATIC_VARIABLE='-DPROBLEM.ProblematicText="/05 abcdef"'
+ SUM='-DNORMAL.NormalText=normal124 -DPROBLEM.ProblematicText="/05 abcdef"'
+ export SUM
+ java -DNORMAL.NormalText=normal124 '-DPROBLEM.ProblematicText="/05' 'abcdef"' -jar ApacheJMeter.jar
Error: Could not find or load main class abcdef"

Anyone have an idea how to solve it?

I want to get:

java -DNORMAL.NormalText=normal124 -DPROBLEM.ProblematicText="/05 abcdef" -jar ApacheJMeter.jar

If you're using bash, you can use arrays.

#!/bin/bash
NORMAL_VARIABLE=-DNORMAL.NormalText=normal124
PROBLEMATIC_VARIABLE=-DPROBLEM.ProblematicText="/05 abcdef"
SUM=($NORMAL_VARIABLE "$PROBLEMATIC_VARIABLE")

And then

java "${SUM[@]}" -jar "ApacheJMeter.jar" "$@"
