Maven安装后缺少类

Question

So I've pretty much been banging my head against the wall trying to solve this one...

This is my first time using Maven, and am using it on OSX to install the ews-java-api.

After clean, or instal, and everything builds successfully, but I am still unable to access the classes through a java file.

I'm getting the following errors,

    Connect.java:3: error: package microsoft.exchange.webservices.data does not exist
    import microsoft.exchange.webservices.data.*;
    Connect.java:15: error: cannot find symbol
    ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
    ^
    symbol:   class ExchangeService
    location: class Connect

I'm curious if I've overall made a mistake with the install path, when installing Maven... or if theres another issue regarding where I'm downloading the API package?

Any help is much appreciated!!

[EDIT] This is my bash.profile output...

    $ cat ~/.bash_profile 
    export M2_HOME=/Users/joliv64/mailtests/apache-maven-3.3.3/
    export PATH=$PATH:$M2_HOME/bin

Also this is my pom.xml file.

Answer 1

Two suspected areas we can have as mentioned in the Comments.

1. Either you don't have dependency for Jar contains the mentioned class.
2. Or If its present then problem is with the .classpath file.

@user1933888/ @Ferdinand Neman/ @Subodh Joshi are very right.

@Zavael- By default scope is compile need not to define explicitly. REFER: https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html

Note: I Don't have right to add comment above so I mentioned here. I am newbie to this portal:-)

Answer 2

So the solution to the problem was much simpler than expected..

I was compiling my file with javac, and did not put my class into a package to compile with mvn.

Also, the imports were a tad off because they were not as advertised from some source code. So of course mvn was building correctly, I was just trying to access the classes in an incorrect manner.

Thanks for the help!
