bash - 作为bash脚本的一部分调用gradle会终止该脚本

Question

首次调用gradlew后，以下脚本将终止。这是为什么？

#!/usr/bin/env sh

find $PWD -maxdepth 1 -type d | while read d; do
  cd $d
  echo "cd" $d
  if [ -e "pom.xml" ]; then
    echo $d " contains pom.xml"
    mvn clean
    echo "cleaned" $d
  fi
  if [ -e "gradlew" ]; then
    echo $d " contains gradlew"
    ./gradlew -q clean
    echo "cleaned" $d
  fi
done 

输出:

$ ./clean-all 
cd /home/user/code
cd /home/user/code/smstest
/home/user/code/smstest  contains gradlew
cleaned /home/bpiech/code/smstest

如果我评论gradle调用，它适用于每个Maven项目。

将while循环更改为for-in循环解决了我的问题。不过，很高兴知道为什么它会以这种方式工作。

#!/usr/bin/env sh

for d in $(find $PWD -maxdepth 1 -type d); do
  cd $d
  echo "cd" $d
  if [ -e "pom.xml" ]; then
    echo $d "contains pom.xml"
    mvn clean
    echo "cleaned" $d
  fi
  if [ -e "gradlew" ]; then
    echo $d "contains gradlew"
    ./gradlew clean
    echo "cleaned" $d
  fi
done
