java - mvnw 权限在 travis 构建期间被拒绝错误

Question

我正在尝试构建应用程序 java-cloud-sample来自 github 使用 travis-ci。

.travis.yml 看起来像这样

language: java
sudo: true
dist: trusty
jdk: oraclejdk9
addons:
  apt:
    packages:
      - oracle-java9-installer
before_script: 
  - chmod a+x ./mvnw

但是当它尝试构建应用程序时出现此错误

$ export PATH=$JAVA_HOME/bin:$PATH
$ java -Xmx32m -version
java version "9"
Java(TM) SE Runtime Environment (build 9+181)
Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode)
$ javac -J-Xmx32m -version
javac 9
3.01s$ ./mvnw install -DskipTests=true -Dmaven.javadoc.skip=true -B -V

Your build has been stopped.

我试图设置 chmod a+x mvnw 但它也没有帮助。有什么问题？

可以试试把before_script改成before_install吗，如下:

language: java
sudo: true
dist: trusty
jdk: oraclejdk9
addons:
  apt:
    packages:
      - oracle-java9-installer
before_install:
  - chmod +x mvnw
