GMaven构建失败，因为“遇到了API不兼容”。

Question

在尝试使用Maven Gmaven插件编译我的项目时，发生了以下错误：

[ERROR] Failed to execute goal org.codehaus.gmaven:gmaven-plugin:1.4:compile (default) on project concorde-web: Execution default of goal org.codehaus.gmaven:gmaven-plugin:1.4:compile failed: An API incompatibility was encountered while executing org.codehaus.gmaven:gmaven-plugin:1.4:compile: java.lang.NoSuchMethodError: org.codehaus.groovy.ast.ModuleNode.getStarImports()Ljava/util/List;

谷歌建议，这是因为在我的依赖链中出现了多个groovy版本。但是，在检查完整依赖树之后，我发现完整树中只有一个依赖项。

以下是我的pom.xml的摘录：

    <!-- Groovy dependencies -->
    <dependency>
        <groupId>org.codehaus.groovy</groupId>
        <artifactId>groovy-all</artifactId>
        <version>1.8.5</version>
    </dependency>
    <!-- ... snip ... -->

        <plugin>
            <groupId>org.codehaus.gmaven</groupId>
            <artifactId>gmaven-plugin</artifactId>
            <version>1.4</version>
            <executions>
                <execution>
                    <goals>
                        <goal>generateStubs</goal>
                        <goal>compile</goal>
                        <goal>generateTestStubs</goal>
                        <goal>testCompile</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>

Answer 1

这是由providerSelection插件定义中缺少的GMaven元素造成的。

正确的GMaven定义如下：

        <plugin>
            <groupId>org.codehaus.gmaven</groupId>
            <artifactId>gmaven-plugin</artifactId>
            <version>1.4</version>
            <configuration>
                <providerSelection>1.8</providerSelection>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>generateStubs</goal>
                        <goal>compile</goal>
                        <goal>generateTestStubs</goal>
                        <goal>testCompile</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

Answer 2

您的问题可能是由Java版本引起的。在这种情况下，我建议将它从Java 17降到Java 8。

只要对马蒂的解决方案做一点小小的修改，我就能让它发挥作用：

<plugin>
        <groupId>org.codehaus.gmaven</groupId>
        <artifactId>gmaven-plugin</artifactId>
        <version>1.5</version>

        <executions>
            <execution>
                <configuration>
                    <providerSelection>2.0</providerSelection>
                </configuration>
                <goals>
                    <goal>generateStubs</goal>
                    <goal>compile</goal>
                    <goal>generateTestStubs</goal>
                    <goal>testCompile</goal>
                </goals>
            </execution>
        </executions>
</plugin>
