We Keep Coding

I am adding Jacoco Maven Plugin in POM file of Apache Tika to get the Code Coverage. But i am facing issues doing so

The Apache Tika Project has a root directory within which there is a pom.xml present. Inside the Root directory there are submodules and module named "Tika-Parent". Inside Parent module there is also a pom.xml file.
Now i am adding jacoco Maven Plugin to Tika to get Code Coverage but i am facing problems because when i add Jacoco Maven Plugin to the Pom.xml in Root Directory. It builds successfully but gives an error :"Skipping JaCoCo execution due to missing execution data file:C:\Users\adity\IdeaProjects\tika-1.20\target\jacoco.exec"
I tried adding JaCOCO Plugin to both the pom.xml files together as well as one by one each also but no result.
Also when I Perform Maven Test on the pom.xml in root directory it builds successfully running all tests.
BUT when I Perform Maven Test on the Tika-parent's pom.xml it doesnt run any tests but builds successfully.
I am attaching below the Pom.xml in root directory as well as pom.xml from Tika-parent module inside the root directory.
I am using IntelliJ Community edition ( latest version on website).
Java version - JDK 8 ,
Maven version 3.
THese details are from Root directory pom.xml

The Jacoco Plugin is present in this pom file too which is same as earlier pom file.
I tried placing in this file and building it. Didnt work. THen tried placing jacoco plugin in Root pom file , didnt work. Gives the same above mentionde error.
Please HELP!!

in my code i insert jacoco plugin in root pom under pluginManagement tag:
<pluginManagement>
<plugins>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.9</version>
<executions>
<execution>
<id>default-prepare-agent</id>
<goals>
<goal>prepare-agent</goal>
</goals>
</execution>
<execution>
<id>default-report</id>
<phase>prepare-package</phase>
<goals>
<goal>report</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</pluginManagement>
And in every sub-module where I do unit test I insert the following pom.xml configuration:
<build>
<plugins>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
You have to enable jacoco plugin only inside java module where there are unit test.

Lombok and AspectJ

I'm trying to use Lombok in combination with AspectJ and Maven.
So, what's the problem?
When I use the AspectJ Maven Plugin (www.mojohaus.org/aspectj-maven-plugin/), it takes the sources and compiles them and ignores changes made by Lombok. I followed this tutorial and came up with this code and AspectJ works, but Lombok dies with this message:
[WARNING] You aren't using a compiler supported by lombok, so lombok will not work and has been disabled.
Your processor is: org.aspectj.org.eclipse.jdt.internal.compiler.apt.dispatch.BatchProcessingEnvImpl
Lombok supports: sun/apple javac 1.6, ECJ
So, does anyone know how to get Lombok in combination with AspectJ working?

Use ajc to process classes.

Use delombok to generate normal source code. And then proceed as you would if Lombok were not being used.
Store your Lombok-annotated code in main/src/lombok (for example) and then have the delombok plugin convert these annotations into normal code and into the directory /delomboked (for example).

I tried various solutions, finally specifying the javac compiler option like the below one worked

This works for me with command line mvn clean install, but in Eclipse IDE, the problem is not solved, eg. log is not correctly recognized for #Slf4j.

I had a configuration/excludes/exclude section with the spring-boot-maven-plugin where the "aspectjweaver" dependency had been declared. The exclude section had "org.projectlombok" in it, and looks like that's why none of my lombok annotations were being processed while building using "mvn clean install"
I initially had this:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<dependencies>
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>

<exclude>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
</exclude>
</excludes>
</configuration>
</plugin>
When I removed the excludes part, then the build started taking the lombok annotations and worked. This is my section now:

Any suggestion ?

This guide shows you step by step to setup Jacoco in your project: http://www.petrikainulainen.net/programming/maven/creating-code-coverage-reports-for-unit-and-integration-tests-with-the-jacoco-maven-plugin/
Step 1: with jacoco-maven-plugin:
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.5.201505241946</version>
<executions>
<!--
Prepares the property pointing to the JaCoCo runtime agent which
is passed as VM argument when Maven the Surefire plugin is executed.
-->
<execution>
<id>pre-unit-test</id>
<goals>
<goal>prepare-agent</goal>
</goals>
<configuration>
<!-- Sets the path to the file which contains the execution data. -->
<destFile>${project.build.directory}/coverage-reports/jacoco-ut.exec</destFile>
<!--
Sets the name of the property containing the settings
for JaCoCo runtime agent.
-->
<propertyName>surefireArgLine</propertyName>
</configuration>
</execution>
<!--
Ensures that the code coverage report for unit tests is created after
unit tests have been run.
-->
<execution>
<id>post-unit-test</id>
<phase>test</phase>
<goals>
<goal>report</goal>
</goals>
<configuration>
<!-- Sets the path to the file which contains the execution data. -->
<dataFile>${project.build.directory}/coverage-reports/jacoco-ut.exec</dataFile>
<!-- Sets the output directory for the code coverage report. -->
<outputDirectory>${project.reporting.outputDirectory}/jacoco-ut</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
Step 2: With maven-surefire-plugin
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.15</version>
<configuration>
<!-- Sets the VM argument line used when unit tests are run. -->
<argLine>${surefireArgLine}</argLine>
<!-- Skips unit tests if the value of skip.unit.tests property is true -->
<skipTests>${skip.unit.tests}</skipTests>
<!-- Excludes integration tests when unit tests are run. -->
<excludes>
<exclude>**/IT*.java</exclude>
</excludes>
</configuration>
Be aware about surefireArgline property, which defined in jacoco-maven-plugin, and used in maven-surefire-plugin.

Try this configuration:
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.5.201505241946</version>
<executions>
<!--
Prepares the property pointing to the JaCoCo runtime agent which
is passed as VM argument when Maven the Surefire plugin is executed.
-->
<execution>
<id>pre-unit-test</id>
<goals>
<goal>prepare-agent</goal>
</goals>
<configuration>
<!-- Sets the path to the file which contains the execution data. -->
<destFile>${project.build.directory}/coverage-reports/jacoco-ut.exec</destFile>
<!--
Sets the name of the property containing the settings
for JaCoCo runtime agent.
-->
<propertyName>surefireArgLine</propertyName>
</configuration>
</execution>
<!--
Ensures that the code coverage report for unit tests is created after
unit tests have been run.
-->
<execution>
<id>post-unit-test</id>
<phase>test</phase>
<goals>
<goal>report</goal>
</goals>
<configuration>
<!-- Sets the path to the file which contains the execution data. -->
<dataFile>${project.build.directory}/coverage-reports/jacoco-ut.exec</dataFile>
<!-- Sets the output directory for the code coverage report. -->
<outputDirectory>${project.reporting.outputDirectory}/jacoco-ut</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<version>2.15</version>
<configuration>
<!-- Sets the VM argument line used when integration tests are run. -->
<argLine>${failsafeArgLine}</argLine>
</configuration>
</plugin>

Adding AspectJ to pom.xml changed Java version with Maven, why?

UPDATE: here is my maven-compiler-plugin configuration:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
I work on a multi-project application that I build with Maven. We decided to add AspectJ so I added the following code to pom.xml in the top level project: (from the official documentation)
<project>
...
<dependencies>
...
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjrt</artifactId>
<version>1.7.3</version>
</dependency>
...
</dependencies>
...
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>
<version>1.5</version>
<executions>
<execution>
<goals>
<goal>compile</goal> <!-- use this goal to weave all your main classes -->
<goal>test-compile</goal> <!-- use this goal to weave all your test classes -->
</goals>
</execution>
</executions>
</plugin>
...
</plugins>
<build>
...
</project>
and the following fragments to each subordinate projects:
</project>
...
<build>
....
<plugins>
...
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
<dependencies>
...
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjrt</artifactId>
</dependency>
....
</dependencies>
...
</project>
Somehow this modification has overridden the Java version I use. If I run build I get multiple errors like this:
Syntax error, annotations are only available if source level is 1.5 or greater
That gives me the suspicion that my Java version (originally 1.6) was somehow reverted to 1.4. I did nothing - at least not knowingly - that could influence the Java version, so I suspect that the above mentioned AspectJ related code is responsible for the change.
My question is how can AspectJ change the Java version and what should I do to fix this problem. Or do I misunderstand something completely and am I on the wrong track?

I think the problem is with the default source, target and complianceLevel settings of the aspectj-maven-plugin (according to the documentation linked previously, 1.4, 1.2 and 1.4 respectively). You should set these explicitly in your parent pom:
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>
<version>1.5</version>
<!-- new configuration is here -->
<configuration>
<complianceLevel>1.6</complianceLevel>
<source>1.6</source>
<target>1.6</target>
</configuration>
<executions>
<execution>
<goals>
<goal>compile</goal>
<goal>test-compile</goal>
</goals>
</execution>
</executions>
</plugin>
...
</plugins>
<build>

I was missing
<complianceLevel>${java.level}</complianceLevel>
in my pom.xml

If you don't have define the version, the compiler plugin assumes that your Java source conforms to Java 1.3 and that you are targeting a Java 1.1 JVM.
Maybe, you should define it:
http://maven.apache.org/plugins/maven-compiler-plugin/examples/set-compiler-source-and-target.html

You can find last versions of dependecy and plugin for aspectj.

I was missing the java version with jdk version at the top of my pom properties.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>
<version>1.2</version> <!-- 1.5 dint work for me -->
<dependencies>
<!-- You must use Maven 2.0.9 or above or these are ignored (see MNG-2972) -->
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjrt</artifactId>
<version>${aspectj.version}</version>
</dependency>
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjtools</artifactId>
<version>${aspectj.version}</version>
</dependency>
</dependencies>
<executions>
<execution>
<phase>process-sources</phase> <!-- or any phase before compile -->
<goals>
<goal>compile</goal>
<goal>test-compile</goal>
</goals>
</execution>
</executions>
<configuration>
<outxml>true</outxml>
<source>${jdk.version}</source> <!-- I was missing this -->
<target>${jdk.version}</target> <!-- jdk.version property -->
</configuration>
</plugin>
and at the top of my pom.xml I had set jdk.version property like,
<properties>
<jdk.version>1.7</jdk.version>
</properties>
