This or a similar warning is emitted by a plugin that processes plain text files but has not been configured to use a specific file encoding. So eliminating the warning is simply a matter of finding out which plugin emits it and how to configure the file encoding for it.
This is as easy as adding the following property to your POM (or one of its parent POMs):
<project> <!-- ... --> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <!-- ... --> </project>
WEB-INF/lib? I need a “compile only” scope!The scope you should use for this is provided. This indicates to Maven that the dependency will be provided at run time by its container or the JDK, for example. Dependencies with this scope will not be passed on transitively, nor will they be bundled in a package such as a WAR, or included in the runtime classpath.
The Available Plugins page lists them and provides additional information.
You can use the Maven Help Plugin's describe goal.
For example, to find out the version of the install plugin:
mvn -Dplugin=install help:describe
Note that you must give the plugin prefix as the argument to plugin, not it's artifact ID.
There are currently two alternatives:
The Maven Ant Tasks allow many of the features of Maven, such as dependency management and repository deployment, to be used in an Ant build.
You must configure the source and target parameters in your pom. For example, to set the source and target JVM to 7, you should have in your pom:
<project> <!-- ... --> <properties> <maven.compiler.source>1.7</maven.compiler.source> <maven.compiler.target>1.7</maven.compiler.target> </properties> <!-- ... --> </project>
Or if a parent pom overrides for compiler plugin default values, and you can‘t fix it, you’ll have to explicitly force the values in the compiler plugin configuration:
<project> <!-- ... --> <build> <!-- ... --> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.3</version> <configuration> <source>1.7</source> <target>1.7</target> </configuration> </plugin> </plugins> <!-- ... --> </build> <!-- ... --> </project>
Absolutely yes!
By configuring <sourceDirectory>, <resources> and other elements of the <build> section. In addition, you may need to change the plugin configuration if you are not using plugin defaults for their files/directories.
The source code can be found in our Subversion and Git repositories. For more information, see Building Maven.
You most probably need to configure Maven to use a proxy. Please see the information on Configuring a proxy for information on how to configure your proxy for Maven.
If you understand the layout of the Maven repository, you can copy the jar directly into where it is meant to go. Maven will find this file next time it is run. If you are not confident about the layout of the Maven repository, then you can adapt the following command to load in your jar file, all on one line.
mvn install:install-file -Dfile=<path-to-file> -DgroupId=<group-id> -DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=<packaging> -DgeneratePom=true Where: <path-to-file> the path to the file to load <group-id> the group that the file should be registered under <artifact-id> the artifact name for the file <version> the version of the file <packaging> the packaging of the file e.g. jar
This should load in the file into the Maven repository, renaming it as needed.
To unsubscribe from a Maven mailing list you simply send a message to [mailing-list]-unsubscribe@maven.apache.org. So, if you have subscribed to users@maven.apache.org then you would send a message to users-unsubscribe@maven.apache.org in order to get off the list.
People tend to have problems when they subscribe with one address and attempt to unsubscribe with another. So make sure that you are using the same address when unsubscribing that you used to subscribe before asking for help.
If you find you still cannot get off a list then send a message to [mailing-list]-help@maven.apache.org. These instructions are also appended to every message sent out on a maven mailing list...
Add the parameter -Dmaven.test.skip=true or -DskipTests=true in the command line, depending on whether you want to skip test compilation and execution or only execution. See the example Skipping Tests in the Surefire Plugin's documentation for more details.
Use the parameter -Dtest=MyTest at the command line. Do not specify the entire package (org.apache.x.y.MyTest).
Configure your ide to use the correct encoding. With Eclipse, add -Dfile.encoding=ISO-8859-1 in eclipse.ini file.
Configure the reporting output encoding in your pom
<project> <!-- ... --> <properties> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> </properties> <!-- ... --> </project>
or if default encoding is overridden in a parent pom that you can't change, configure the site plugin explicitly
<project> <!-- ... --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-site-plugin</artifactId> <version>3.6</version> <configuration> <outputEncoding>UTF-8</outputEncoding> </configuration> </plugin> <!-- ... --> </project>
Configure the file encoding used by mvn and add the encoding to MAVEN_OPTS (same as the ide). This can be made with adding MAVEN_OPTS="-Dfile.encoding=ISO-8859-1" in $HOME/.profile.
Tests are run by the surefire plugin. The surefire plugin can be configured to run certain test classes, and you may have unintentionally done so by specifying a value to ${test}. Check your settings.xml and pom.xml for a property named test which would like this:
<project> <!-- ... --> <properties> <property> <name>test</name> <value>some-value</value> </property> </properties> <!-- ... --> </project>
or
<project> <!-- ... --> <properties> <test>some-value</test> </properties> <!-- ... --> </project>
If you are trying to build a development version of Maven or plugins, you may need to access the Maven snapshot repositories. You need to update your settings.xml file using the Guide to Plugin Snapshot Repositories.
See the following links:
Your favorite IDE probably supports XSD schema's for pom.xml and settings.xml editing. You need to specify the following:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <!-- ... --> </project>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd"> <!-- ... --> </settings>
We have compiled a list of available resources on the getting help page.
You could call Maven with -X parameter or -e parameter. For more information, run: mvn --help.
A mojo is a Maven plain Old Java Object. Each mojo is an executable goal in Maven, and a Maven plugin is a distribution of one or more related mojos.
You could use the following search engines:
With MNG-5940 the release profile goal of the Maven Javadoc Plugin has been changed to jar-no-fork. Revise your configuration to avoid duplicate JAR upload.
