Java – Maven changes the order of plug-ins for different configuration files
I have a POM XML, I defined the same plug-in in two different configuration files (the same groupid and artifactid, different execution: -) Execution is defined in the same phase, so the order is calculated by the order of XML:
<?xml version="1.0" encoding="UTF-8" standalone="no"?> <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 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>echo</groupId> <artifactId>test</artifactId> <name>echo-test</name> <version>1.0.0</version> <packaging>pom</packaging> <profiles> <profile> <id>1st-profile</id> <activation> <activeByDefault>true</activeByDefault> </activation> <build> <plugins> <plugin> <artifactId>maven-antrun-plugin</artifactId> <executions> <execution> <id>1st-antrun-echo</id> <phase>test</phase> <goals> <goal>run</goal> </goals> <configuration> <tasks> <echo>1st antrun plugin</echo> </tasks> </configuration> </execution> </executions> </plugin> </plugins> </build> </profile> <profile> <id>2nd-profile</id> <activation> <activeByDefault>true</activeByDefault> </activation> <build> <plugins> <plugin> <groupId>com.soebes.maven.plugins</groupId> <artifactId>maven-echo-plugin</artifactId> <version>0.1</version> <executions> <execution> <id>1st-soebes-echo</id> <phase>test</phase> <goals> <goal>echo</goal> </goals> <configuration> <echos> <echo>1st echo-plugin</echo> </echos> </configuration> </execution> </executions> </plugin> <plugin> <artifactId>maven-antrun-plugin</artifactId> <executions> <execution> <id>2nd-antrun-echo</id> <phase>test</phase> <goals> <goal>run</goal> </goals> <configuration> <tasks> <echo>2nd antrun plugin</echo> </tasks> </configuration> </execution> </executions> </plugin> </plugins> </build> </profile> </profiles> </project>
All plug-in execution is defined in the test phase, so I expect the following order:
1st antrun plugin 1st echo-plugin 2nd antrun plugin
However, since antrun plugins are merged, I get this output:
1st echo-plugin 1st antrun plugin 2nd antrun plugin
This command explains why this happens: MVN help: effective POM
In addition to introducing new phases, are there other solutions to maintain orders? Our project is really big. This is a very simple example
Why does Maven's restriction merge plug-ins into multiple executing plug-ins?
Solution
In my experience, this is one of the biggest bugs in Maven If you configure multiple configurations for the same plug-in in different configuration files, the command is unpredictable at all I even observed that I have some plug-in order in project B at a given stage. Once the same plug-in gets a configuration in a parent project (not even in the same stage), this command is destroyed
stay https://jira.codehaus.org/browse/MNG-2258 There is an obvious error closing the bug
Possible solutions
If possible, try to move some plug-ins to the previous stage (prepare to test some plug-ins and test the rest) > try to replace the function of multiple plug-ins with a groovy Maven plug-in script (it is very convenient to integrate with ants and you will reach the list of active configuration files in the script) write your own Mojo and call the plug-ins in the correct order (see https://github.com/TimMoore/mojo-executor )> give it a try Maybe it meets your needs. It brings a lot of good things from Maven
I don't think there's anything else to do now
