Does not run on "mvn compile" #14

4ntoine · 2018-02-05T13:21:14Z

I have added plugin to generate wrapper for smart contract:

          <plugin>
                <groupId>org.web3j</groupId>
                <artifactId>web3j-maven-plugin</artifactId>
                <version>0.1.5-SNAPSHOT</version>
                <configuration>
                    <packageName>name.antonsmirnov.apptogether.ethereum</packageName>
                    <sourceDestination>target/generated-sources/java</sourceDestination>
                    <nativeJavaType>true</nativeJavaType>
                    <soliditySourceFiles>
                        <directory>src/main/resources</directory>
                        <includes>
                            <include>**/*.sol</include>
                        </includes>
                    </soliditySourceFiles>
                </configuration>
                <executions>
                    <execution>
                        <phase>generate-sources</phase>
                        <goals>
                            <goal>generate-sources</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

I'm running mvn generate-sources in parent maven module using the plugin.
However i can't see any generating output:

I've tried to call $mvn web3j:generate-sources in parent project too:

$mvn web3j:generate-sources
...

Of coarse i have .sol file(s):

$ls ethereum/src/main/resources/
.                       ..                      AppetissimoContract.sol

The text was updated successfully, but these errors were encountered:

I've found it works as expected if running mvn compile on the module directly (in ./ethereum directory), not on parent module. Did i miss anything?

PS. Parent module:

<?xml version="1.0" encoding="UTF-8"?>
<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/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>name.antonsmirnov.apptogether</groupId>
    <artifactId>parent</artifactId>

        ...
    </modules>

</project>

I think you should specify the plugin in the pluginManagement section of the multi-module root pom.

    <modules>
        ...
        <module>ethereum</module>
        ...
    </modules>
 
  <build>
    <!-- In the multi-module root pom, use the pluginManagement to define the version of the maven-plugin -->
    <pluginManagement>
      <plugins>
          <plugin>
                <groupId>org.web3j</groupId>
                <artifactId>web3j-maven-plugin</artifactId>
                <version>0.1.5-SNAPSHOT</version>
          </plugin>
      </plugins>
    </pluginManagement>
  </build>

And in the specific module ethereum, clear the version of the plugin, since it is already defined in the multi-module root pom (the parent).

  <parent>
    <groupId>name.antonsmirnov.apptogether</groupId>
    <artifactId>parent</artifactId>
    <version>1.0</version>
    <relativePath>../</relativePath>
  </parent>
 
  <build>
    <plugins>
      <plugin>
        <groupId>org.web3j</groupId>
        <artifactId>web3j-maven-plugin</artifactId>
        <!-- No version needed here, it is already defined in the multi-module root pom -->
        <configuration>
          <!-- This is where our specific configuration goes -->
        </configuration>
      </plugin>
    </plugins>
  </build>

I did what you've suggested - it still does not work. Neither mvn clean generate-sources nor mvn clean web3j:generate-sources on parent module:

$mvn clean generate-sources

To make it working and behaving like other code generating plugins (jaxws for example), I had to add the following:

<build>
        <plugins>
            <plugin>
                <groupId>org.web3j</groupId>
                <artifactId>web3j-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <id>generate-sources</id>
                        <phase>generate-sources</phase>
                        <goals>
                            <goal>generate-sources</goal>
                        </goals>
                        <configuration>
                            <soliditySourceFiles>
                                <directory>${basedir}/src/main/solidity</directory>
                                <includes>
                                    <include>**/*.sol</include>
                                </includes>
                            </soliditySourceFiles>
                            <sourceDestination>${basedir}/target/generated-sources/solidity</sourceDestination>
                            <packageName>my.package.name.here</packageName>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>build-helper-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <id>add-source</id>
                        <phase>generate-sources</phase>
                        <goals>
                            <goal>add-source</goal>
                        </goals>
                        <configuration>
                            <sources>
                                <source>${basedir}/target/generated-sources/solidity</source>
                            </sources>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

The above should be the default behavior of the web3j-maven-plugin plugin I guess...

4ntoine · 2018-02-26T18:15:48Z

That's strange but it still does not work for me. The only thing that i've found is that you've added <id>...</id>. Anything else?

Here is my pom.xml:

                    <goals>
                        <goal>add-source</goal>
                    </goals>
                    <configuration>
                        <sources>

                    </configuration>

You need the build-helper-maven-plugin configuration too, else maven-compiler-plugin won't pick up the generated Java sources.
Also, ${basedir} prefix is required within a multi-module project.

You were right @fcorneli. Thanks a lot!
