How can the maven build be made to continue despite an error in one of the execution added by the Maven exec plugin?
https://www.mojohaus.org/exec-maven-plugin/usage.html
Example solution using success code:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>3.0.0</version>
<executions>
<execution>
<id>docker-rmi</id>
<phase>clean</phase>
<goals>
<goal>exec</goal>
</goals>
<configuration>
<executable>docker</executable>
<workingDirectory>${project.basedir}</workingDirectory>
<arguments>
<argument>rmi</argument>
<argument>${project.groupId}/${project.artifactId}:${project.version</argument>
</arguments>
<successCodes>
<successCode>0</successCode>
<successCode>1</successCode>
</successCodes>
</configuration>
</execution>
</executions>
</plugin>
You can use successCodes and list the error codes what you want to treat as success.
This was created for non-compliant application according to the docs docs but it is useful for such scenario.
I don't know any wildcard solution so you have to explicitly state the list of error codes for the successCodes.

When I run a build with maven using the exec-maven-plugin, it runs everything twice for some reason. Is there a way to fix this so it only runs once? I've tried setting my phase in the pom.xml to compile and package and either way, it runs twice. My pom looks like
<build>
<plugins>
<plugin>
<artifactId>exec-maven-plugin</artifactId>
<groupId>org.codehaus.mojo</groupId>
<version>1.0</version>
<executions>
<execution>
<id>foo</id>
<phase>compile</phase>
<goals>
<goal>exec</goal>
</goals>
</execution>
</executions>
<configuration>
<executable>bash</executable>
<commandlineArgs>myscript.sh</commandlineArgs>
</configuration>
</plugin>
</plugins>
</build>
It turned out that adding the phase tag caused the command to get executed twice. Leaving that out, it is now getting run once as expected. I guess it doesn't matter what phase I give it now, it'll always run the goal, which works for me.
If you need to run this early in the build, excluding the phase isn't an option.
You can do something like this instead in the plugin config:
<executions>
<execution>
<id>default</id>
<phase>none</phase> <!-- disable the default execution in validate phase -->
</execution>
<execution>
<id>exec-do-something</id>
<goals>
<goal>java</goal>
</goals>
<phase>generate-sources</phase><!-- now it will run once but in an earlier phase -->
</execution>
</executions>
I saw this happening due to the inclusion of:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-source-plugin</artifactId>
<version>3.0.1</version>
<executions>
<execution>
<id>attach-sources</id>
<goals>
<goal>jar</goal>
</goals>
</execution>
</executions>
</plugin>
This seems to be that the maven-source-plugin causes a re-execution of the generate-sources phase. See https://maven.apache.org/plugins/maven-source-plugin/jar-mojo.html
Invokes the execution of the lifecycle phase generate-sources prior to executing itself.
If I removed this plugin, the exec goal only executed once.
I have integrated FindBugs plugin to fail the build in case of bugs.
Then using that brilliant answer I configured FindBugs to generate html reports (xml version is barely readable).
The problem is that I have failOnError property set to true, which means that the build would fail in case of bug.
.....
<configuration>
.....
<failOnError>true</failOnError>
</configuration>
And then no html report would be generated.
I read about Maven build lifecycle and there is no such thing as "Execute on fail" (like finally block in Java). So, are there any possible workarounds?
And shouldn't it be out-of the box Maven feature?
Special thanks to #SpaceTrucker for workaround suggestion.
Here is the configuration I ended up with:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>findbugs-maven-plugin</artifactId>
<version>3.0.4</version>
<configuration>
<effort>Max</effort>
<threshold>Low</threshold>
<findbugsXmlOutputDirectory>${project.build.directory}/findbugs</findbugsXmlOutputDirectory>
</configuration>
<executions>
<execution>
<id>noFailOnError</id>
<phase>verify</phase>
<goals>
<goal>check</goal>
</goals>
<configuration>
<failOnError>false</failOnError>
</configuration>
</execution>
<execution>
<id>failOnError</id>
<phase>install</phase>
<goals>
<goal>check</goal>
</goals>
<configuration>
<failOnError>true</failOnError>
</configuration>
</execution>
</executions>
</plugin>
The solution is to use different configurations in verify and install phases.
Note, that according to that answer transformation (to html) is executed in verifyphase.
Issue was submitted for html report generation.
Results are also can be seen by simply run mvn findbugs:gui
I am following this guide and trying to understand the following note:
All of these chunks of code, the io.spring.guides classes will report
compile-time errors in your IDE unless you have run the task to
generate the domain classes based on the WSDL.
I want my xsd schema turn into POJO classes. Which task should I run to make it happen?
I added
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxb2-maven-plugin</artifactId>
<version>1.6</version>
<executions>
<execution>
<id>xjc</id>
<goals>
<goal>xjc</goal>
</goals>
</execution>
</executions>
<configuration>
<schemaDirectory>${project.basedir}/src/main/resources/</schemaDirectory>
<outputDirectory>${project.basedir}/src/main/java</outputDirectory>
<clearOutputDir>false</clearOutputDir>
</configuration>
</plugin>
and executed mvn clean install
I have the findbugs plugin working fine in my maven setup. I've setup findbugs to execute during the compile phase. I noticed however that it runs during the test phase as well because the test phase also calls compile. Because I have an automated build pipeline that runs all my targets, I don't need findbugs to run during the test phase. I've tried to exclude findbugs from the test phase with the following but no luck yet.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>findbugs-maven-plugin</artifactId>
<version>2.4.0</version>
<inherited>true</inherited>
<configuration>
<failOnError>${findbugs.failOnError}</failOnError>
<skip>${findbugs.skip}</skip>
<trace>${findbugs.trace}</trace>
</configuration>
<executions>
<execution>
<phase>compile</phase>
<goals>
<goal>check</goal>
</goals>
</execution>
<execution>
<id>findbugs-test-compile</id>
<phase>test</phase>
<goals>
<goal>check</goal>
</goals>
<configuration>
<skip>true</skip>
</configuration>
</execution>
</executions>
</plugin>
It will not be called based on the running through the life-cylcle via compile it simply is running cause you configured to have two executions one in test and one in compile phase. Findbugs should usually run in the reporting area(site).
Just make a single execution:
<executions>
<execution>
<id>findbugs-test-compile</id>
<phase>test</phase>
<goals>
<goal>check</goal>
</goals>
<configuration>
<skip>true</skip>
</configuration>
</execution>
</executions>
The one you like to have. But i recommend to read the documentation cause it should run in reporting area (via site) only.
UPDATE:
If you like to run findbugs only during the site generation than just remove it from the usual build area and put into the reporting area instead.
We've a requirement where we need to auto generate the code and use it in another project.
I'm using following code for autogenerating the code. But doing a "maven package" only generates sources and it doesn't give any errors in the log. Any help would be much appreciated.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.1</version>
<executions>
<execution>
<id>exec-one</id>
<phase>compile</phase>
<configuration>
<mainClass>com.xx.yy.zzz.aa.bb.Autgen</mainClass>
<arguments>
<argument>-o</argument>
<argument>${srcOutputDir}/${packageDir}</argument>
</arguments>
</configuration>
<goals>
<goal>java</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
First i would suggest to generate the code in a different phase like generate-sources and next you have to tell the compiler plugin to compile that generated code as well. Take a look at the build-help-plugin for this purpose.
