我正在尝试在build.gradle(Project) 上运行当前任务并收到以下错误：
java.io.IOException：错误=13，权限被拒绝。
task ("modifyStrings") {
doLast{
exec{
workingDir '.'
executable "./strings_script.sh"
}
}
}
如果我尝试这样：
task modifyStrings(type: Exec) {
doLast{
workingDir '.'
commandLine "./strings_script.sh"
}
}
它还给我：
java.lang.IllegalStateException: execCommand == null！
我究竟做错了什么？（脚本在android项目的根目录下）
PS：在同一个文件中有另一个任务，很久以前创建的，这就是为什么我把我的任务也放在这里，如果这很重要的话。
task clean(type: Delete) {
delete rootProject.buildDir
}
