I am stuck with using maven for build and compile , but now introducing JavaScript building and automation has provided an interesting challenge, that can we use maven to install Grunt?
I have searched and found a lot of pom.xml examples ,example running grunt and yoeman, etc but NONE for installing grunt
something like:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.2.1</version>
<executions>
<execution>
<id>Install Grunt</id>
<phase>prepare-package</phase>
<goals>
<goal>exec</goal>
</goals>
<configuration>
<executable>grunt</executable>
<arguments>
<argument>install</argument>
</arguments>
</configuration>
</execution>
</executions>
</plugin>
Sorry, this is a very late answer... by using the frontend maven plugin you "install" Grunt by putting it in package.json. Then, npm will download it for you. (Like in the example project)

Is it possible to conditionally run a maven plugin only if a specific directory doesn't exist?
I'm essentially trying to prevent npm ci from running unnecessarily as package.json rarely changes. So ideally it would only run when node_modules doesn't exists.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.2.1</version>
<executions>
<execution>
<id>npm-install</id>
<phase>prepare-package</phase>
<goals>
<goal>exec</goal>
</goals>
<configuration>
<executable>npm</executable>
<arguments>
<argument>ci</argument>
</arguments>
</configuration>
</execution>
</executions>
</plugin>
You can wrap it into a profile and activate that profile only if a given file does not exist.
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.
Maven + npm install
I have following plugin to install package.json dependencies, is there a way i can run npm config set registry and npm config set proxy command with following plugin ?
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<executions>
<execution>
<id>exec-npm-install</id>
<phase>generate-sources</phase>
<goals>
<goal>exec</goal>
</goals>
<configuration>
<executable>npm</executable>
<arguments>
<argument>install</argument>
</arguments>
<workingDirectory>${basedir}/src/main/webapp</workingDirectory>
</configuration>
</execution>
</executions>
</plugin>
was able to get it done through .nprmc file on project root
create file and have entry like
registry=
proxy=
I want to execute this command:
zipalign [-f] [-v] <alignment> infile.apk outfile.apk
Using Maven. I have to execute this command in the Android SDK/ tools directory. Can anyone help me on how to do this? I think this can be done using batch file but I am not sure how to create a batch file. I need this command to be executed when I type "mvn clean install". Thanks
Executing commands using Maven
You can use the Maven Exec Plugin bound to the install phase.
In the snippet below, the commant ping with the argument 8.8.8.8 will be executed every time you do a mvn install:
<project>
...
<build>
<plugins>
<plugin>
<artifactId>exec-maven-plugin</artifactId>
<groupId>org.codehaus.mojo</groupId>
<version>1.2.1</version>
<executions>
<execution>
<id>My Command Runner</id>
<phase>install</phase>
<goals>
<goal>exec</goal>
</goals>
<configuration>
<executable>ping</executable>
<arguments>
<argument>8.8.8.8</argument>
</arguments>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
...
</project>
And that's it.
Update:
I see now what you really having trouble with is executing zipalign, not an arbitrary command. For that, there are two ways.
Using the built-in zipalign of the maven-android-plugin
As of release 2.5.0 of the Android Maven Plugin the zipalign goal is part of the plugin. To activate simply add the goal zipalign as an execution (e.g. to the package phase) and set the skip parameter in the plugin configuration to false:
<zipalign><skip>false</skip></zipalign>
Full <plugin> tag example:
<plugin>
<groupId>com.jayway.maven.plugins.android.generation2</groupId>
<artifactId>maven-android-plugin</artifactId>
<inherited>true</inherited>
<configuration>
<sign>
<debug>false</debug>
</sign>
<zipalign>
<verbose>true</verbose>
<inputApk>${project.build.directory}/${project.artifactId}.apk</inputApk>
<outputApk>${project.build.directory}/${project.artifactId}-signed-aligned.apk
</outputApk>
</zipalign>
</configuration>
<executions>
<execution>
<id>alignApk</id>
<phase>package</phase>
<goals>
<goal>zipalign</goal>
</goals>
</execution>
</executions>
</plugin>
Sources:
Here you'll find an example using the an older version (still called android-maven-plugin);
ZipalignAPKBuiltByMAven: Describes how to automatically zipalign an APK that has been built by Maven.
Simpligility: Maven Android Plugin with zipalign and improved verification
Another example: A full pom.xml that uses the zipalign.
Zipalign using Exec-Maven Plugin
The code below will bind the functionality of zip aligning to the package phase, overwriting previous zip aligned file without asking.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.1.1</version>
<executions>
<execution>
<id>zipalign</id>
<goals>
<goal>exec</goal>
</goals>
<phase>package</phase>
<configuration>
<executable>${ANDROID_HOME}/tools/zipalign</executable>
<arguments>
<argument>-f</argument>
<argument>4</argument>
<argument>target/${project.build.finalName}.apk</argument>
<argument>target/${project.build.finalName}-zipped.apk</argument>
</arguments>
</configuration>
</execution>
</executions>
</plugin>
Please note that this profile has to be added to the pom for the actual APK. You can't add it to a parent pom. The reason for this is that it uses the Maven property that defines the artefact name (project.build.finalName).
If you're building an Android project with Maven, you should be using the maven-android-plugn, which supports the zipalign tool directly.
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.
