AspectJ Maven Plugin cannot compile my project

Question

I try to use aspectj maven plugin for compile project with aspectj compiler and then I try to package classes into \"war\" file. Unfortunately, it doesn\'t work with following c

Answer 1

It will be work after change plugin configuration to following:

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>aspectj-maven-plugin</artifactId>
    <version>1.6</version>
    <configuration>
        <complianceLevel>1.7</complianceLevel>
        <source>1.7</source>
        <target>1.7</target>
        <encoding>UTF-8</encoding>
    </configuration>
    <executions>
        <execution>
            <phase>process-sources</phase>
            <goals>
                <goal>compile</goal>
            </goals>
            <configuration>
                <complianceLevel>1.7</complianceLevel>
                <source>1.7</source>
                <target>1.7</target>
            </configuration>
        </execution>
    </executions>
</plugin>

But after this I get a lot of different compilation errors:

[ERROR] Failed to execute goal org.codehaus.mojo:aspectj-maven-plugin:1.6:compile (default) on project tvbs-portlet: Compiler errors:
[ERROR] error at Entitle.class, entitleId, LockModeType.PESSIMISTIC_WRITE);
[ERROR]
[ERROR] /Users/<...>/ejb/BillingEJB.java:43:0::0 PESSIMISTIC_WRITE cannot be resolved or is not a field
[ERROR] error at .createQuery("select e from Entitle e " +
[ERROR]
[ERROR] /Users/<...>/ejb/EntitleEJB.java:62:0::0 The method createQuery(String) in the type EntityManager is not applicable for the arguments (String, Class<Entitle>)
[ERROR] error at return entityManager.createQuery(
[ERROR] ^^

Can cause is incorrect aspectj plugin parameters?

Having looked at your Maven project https://github.com/dmitrievanthony/test-aspectj I found out that

• the problem is totally unrelated to AspectJ Maven Plugin,
• the same compilation errors also occur in Maven Compiler Plugin and
• that the root cause of your problem is simply bad dependency management.

Here is a screenshot (full size here) from IntelliJ IDEA's "find class":

As you can see, class LockModeType is found in 3 (three!) dependencies, one of which contains a version of the class which does not contain the expected enum values. Your code compiles if you remove this dependency.

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>ejb3-persistence</artifactId>
        <version>1.0.2.GA</version>
    </dependency>

Maybe you should clean up your dependencies. You can use the Maven Dependency Plugin with goals like dependency:analyze and dependency:tree for that purpose.

Answer 3

It seems like a known issue http://jira.codehaus.org/browse/MASPECTJ-125

You can fix it by adding the following to your pom file.

<complianceLevel>1.6</complianceLevel>

Answer 4

Update: While the things I said about AspectJ Maven configuration in this answer are all correct, the root cause of the concrete problem at hand - bad Maven dependency management - is described in my other answer. It would be better if that one was the accepted answer and not this one.

• User codelion's hint makes sense, please change your <compilationLevel> tag (typo?) - to <complianceLevel>.
• There is no need to downgrade to plugin version 1.6, you can keep 1.7.
• There is also no need to specify the configuration again within the <execution> section, the one at plugin level is enough.
• Please note that the default AspectJ version in plugin 1.7 is 1.8.2, so maybe your runtime dependency on 1.7.4 works, but if I were you I would upgrade that one too, optimally in sync with the plugin version. It is no hard requirement, but I think it makes sense.
• Maybe you even want to upgrade to the current version AspectJ 1.8.4, in the plugin as well as the runtime. This can also be achieved by adding a dependency to the desired aspectjtools version to the plugin configuration:

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <java.source-target.version>1.8</java.source-target.version>
        <aspectj.version>1.8.4</aspectj.version>
    </properties>

    <build>

                <plugin>

                    <artifactId>aspectj-maven-plugin</artifactId>
                    <version>1.7</version>
                    <configuration>

Answer 5

make sure the modules has source code,like *.java etc. when i compile CAS on version 4.0.6 it happens this error, I found the cas-server-uber-webapp doesn't has any source code in src folder. just remove the module from parent pom.xml.
