jib-maven-plugin:2.5.0:build failed - NullPointerException in getSpringBootRepackageConfiguration #2687

tomikmar · 2020-08-10T11:08:49Z

Environment:

Jib version: 2.5.0
Build tool: maven:3.6.3-amazoncorretto-11
OS: Amazon Linux 2

Description of the issue:

After upgrading from 2.4.0 to 2.5.0 we have NullPointerException during build. It looks that the issue is in getSpringBootRepackageConfiguration when spring-boot-maven-plugin configuration section is not provided.

Steps to reproduce:

Use spring-boot-maven-plugin without configuration section (we also don't have this section in our parent pom):

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>

Workaround:

Just add configuration (may be empty):

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration></configuration>
        </plugin>

Log output:

Sorry, this is from #2526.

I can't reproduce this. (I am interested in seeing a reproducible sample project to understand why this can happen so that we can prevent similar issues in the future, but it's totally up to you.) However, it's an easy fix anyway.

chanseokoh · 2020-08-10T18:25:07Z

@tomikmar ~~we just released Jib Maven 2.5.1 with the fix.~~

UPDATE: the fix in 2.5.1 is problematic. Use Jib Maven 2.5.2.

tomikmar · 2020-08-11T12:40:27Z

Thanks for the fix. This is the minimal example (3 files) that you can use to reproduce the issue.

Thanks for the sample. I guess the issue is reproducible when

A parent POM defines <pluginManagement> (with spring-boot-maven-plugin in it).
A child module inherits the parent POM and have no <configuration> in spring-boot-maven-plugin.

OTOH, I wasn't able to reproduce it with the usual Spring Boot quickstart project whose parent POM points to org.springframework.boot:spring-boot-starter-parent.
