mvnw权限被拒绝错误时特拉维斯建立

Question

我使用travis-ci试图从github构建应用java-cloud-sample。

.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，当它试图建立应用程序，我得到这个错误

$ 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

Your build has been stopped. 

我试图设置chmod a+x mvnw，并没有帮助。问题是什么？

你可以尝试改变before_script到before_install，如下：

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