Spring Boot JNDI not found - can't compile WAR with Maven

i can't mvn clean install my project. I need to use a remote JNDI in WAR(not jar), but having the name in application.properties throws error during mvn clean install(due to "datasource jndi name not found")

if I have to use jndi name from a remote server, that I have no control over, how do i compile my package in WAR without lookup fail, but let it look up during the deployment/installation of the app on the server? any hint, or direction is very much appreicated...

in app prop, i have

spring.datasource.jndi-name=jdbc/ff-app

I have tried: Spring boot JNDI datasource lookup failure - Name comp/env/jdbc not found in context "java:"

tried, http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#boot-features-connecting-to-a-jndi-datasource

and pretty much every questions asked in stackoverflow about a remote jndi..

Some of the errors:

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.jdbc.datasource.lookup.DataSourceLookupFailureException: Failed to look up JNDI DataSource with name 'jdbc/ff-app'; nested exception is javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial at org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate(SimpleInstantiationStrategy.java:189) ~[spring-beans-4.3.6.RELEASE.jar:4.3.6.RELEASE] at org.springframework.beans.factory.support.ConstructorResolver.instantiateUsingFactoryMethod(ConstructorResolver.java:588) ~[spring-beans-4.3.6.RELEASE.jar:4.3.6.RELEASE] ... 69 common frames omitted Caused by: org.springframework.jdbc.datasource.lookup.DataSourceLookupFailureException: Failed to look up JNDI DataSource with name 'jdbc/ff-app'; nested exception is javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial at org.springframework.jdbc.datasource.lookup.JndiDataSourceLookup.getDataSource(JndiDataSourceLookup.java:48) ~[spring-jdbc-4.3.6.RELEASE.jar:4.3.6.RELEASE] at org.springframework.boot.autoconfigure.jdbc.JndiDataSourceAutoConfiguration.dataSource(JndiDataSourceAutoConfiguration.java:62) ~[spring-boot-autoconfigure-1.5.1.RELEASE.jar:1.5.1.RELEASE] at org.springframework.boot.autoconfigure.jdbc.JndiDataSourceAutoConfiguration$$EnhancerBySpringCGLIB$$9509801a.CGLIB$dataSource$0() ~ ........

Solution

The point is that when you try to compile by using maven, maven tries to execute also Junit tests; in your case you have in src/resources/java some unit tests and so maven tries to execute them. Since you are using a JNDI datasource, it means that also the servlet container must be active for executing tests otherwise you can't get connection.

In this case when maven tries to execute tests maybe no servlet container (and, so, no JNDI datasource) is active and your test throws error.

To solve this (and to compile the maven artifact) you must:

or exclude tests execution: this is done by adding <maven.test.skip>true</maven.test.skip> in pom.xml. No test will be executed
or ignore tests error this is done by adding <maven.test.failure.ignore>true</maven.test.failure.ignore> in pom.xml. In this case tests will be executed but any test error will not stop maven compilation

The configuration I gave not only tells maven to not execute tests but it tells maven to not stop on any test error

I hope i have been clearer... my english is not the best
