我正在尝试构建azure AD library for java，但是在构建时出现此错误，为什么？

最佳答案
我试图重现该问题，但失败了。我从GitHub克隆了adal4j存储库，并通过命令mvn package成功将其打包。
这是我环境中的步骤。
OS: Ubuntu 14.04 LTS
Java SDK: JDK 1.8.0u51 64bit
Maven: 3.3.9
在
~/.profile文件中设置JDK和Maven的环境。export JAVA_HOME=~/<my-sdk-path>/jdk1.8.0_51
export CLASSPATH=.:$JAVA_HOME/lib
export PATH=$JAVA_HOME/bin:$PATH
export M2_HOME=~/<my-sdk-path>/apache-maven-3.3.9
export PATH=$PATH:$M2_HOME/bin
检查JDK和Maven
~ $ java -version
~ $ mvn -v
克隆项目
adal4j的当前存储库。~ $ git clone https://github.com/AzureAD/azure-activedirectory-library-for-java.git
打包
adal4j项目。~ $ cd azure-activedirectory-library-for-java
~ $ mvn package
我尝试通过导入现有的Maven项目选项并在Eclipse中导出jar文件来打包它，它也可以成功运行。
因此，我认为该问题可能是由环境变量（如
PATH）引起的，无论您使用Windows还是其他操作系统。请尝试清理您的环境或使用某些IDE（例如Eclipse）进行编译。希望能帮助到你。如有任何疑问，请随时告诉我。
