http 401 for Spring Tutorial when running "ant list"

I'm tired of Googling.

I'm getting this stacktrace when running "ant list" from the command-line:

Here is my build.properties:

tomcat.manager.url=http://localhost:8080/manager/html
tomcat.manager.username=tomcat
tomcat.manager.password=s3cret


Here is the contents of tomcat-users.xml:

<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<role rolename="tomcat"/>
<role rolename="role1"/>

<user username="tomcat" password="s3cret" roles="manager-gui"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
<user username="role1" password="tomcat" roles="role1"/>


Anyone know what's going on? Thanks!

Answer

As mentioned by GreyBeardedGeek 401 clearly means authorization issue. You will need to configure manager role and access to tomcat, from your tomcat-users.xml i can see two issue 1) tomcat user has been defined twice 2) no role defined as "manager"

i think it you tomcat-users.xml should look like

<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<role rolename="tomcat"/>
<role rolename="role1"/>
<role rolename="manager"/>

<user username="tomcat" password="s3cret" roles="manager-gui,manager"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
<user username="role1" password="tomcat" roles="role1"/>

i am not sure what/how you are going to use manager-gui,manager-script,manager-jmx but for security purpose you should also remove un-necessary users "both" and "role1".

for configuring manager access you can refer to tomcat documentation
