maven compilation failure

Question

I have a weird problem - Some class file couldn\'t be read during maven build.

1. I have a project A and project B.
2. Project

Answer 1

It COULD be due to insufficient heap memory.

It sounds strange, but try it, it might just work:

export MAVEN_OPTS='-Xms384M -Xmx512M -XX:MaxPermSize=256M'

Answer 2

Just now I also met the problem

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project entry-api: Compilation failure: Compilation failure:

package com.foo.entry.common.domain does not exist
package com.foo.entry.common.model does not exist
package com.foo.entry.common.service does not exist
package com.foo.entry.common.util does not exist

Took a long time got the reason, that is one of the dependency jar is spring boot fat jar, so the solution is move below code in its pom.xml

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

Answer 4

If your dependencies are fine (check with mvn dependency:list) like mine were, then it's a maven glitch, if you're using Eclipse do:

1. Right click the project > Maven > Update Project...
2. Check everything but Offline
3. OK

You should be good.

I don't know the equivalent mvn commands, if anyone could post them they could be useful.

Answer 5

Add <sourceDirectory>src</sourceDirectory> in your pom.xml with proper reference. Adding this solved my problem

Answer 6

Inside in yours classses on which is complain maven is some dependecy which belongs to some jar's try right these jars re-build with maven command, i use this command mvn clean install -DskipTests=true should be work in this case when some symbols from classes is missing
