travis构建期间mvnw权限被拒绝错误

Question

我试图建立应用程序的Java云样品从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.

我正在尝试设置chmod a+x mvnw，但也没有帮助。问题是什么？

您可以尝试更改before_script为before_install吗，如下所示：

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