Question

我正在尝试使用Maven构建项目。不幸的是我没有maven的经验所以我有点无奈。它很可能是由riak子模块引起的。这是代码为YCSB

的github仓库

我的系统：

Apache Maven 3.2.2 (NON-CANONICAL_2015-04-01T06:56:20_mockbuild; 2015-04-01T08:56:20+02:00)

Java version: 1.8.0_51, vendor: Oracle Corporation

OS name: "linux", version: "4.1.5-100.fc21.x86_64", arch: "amd64", family: "unix"

Maven堆栈跟踪：

[ERROR] After correcting the problems, you can resume the build with the command
[ERROR]   mvn <goals> -rf :ycsb

我不知道这意味着什么所以我猜你是我唯一的希望：D

编辑：添加Subodh Joshi建议的插件后：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.5.5:single (default) on project binding-parent: Failed to create assembly: Error creating assembly archive jar-with-dependencies: You must set at least one file.

EDIT2： mvn compile工作正常，但mvn package因上述错误而失败。

您必须在maven-assembly-plugin文件中添加pom.xml

 <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>
        <archive>
          <manifest>
            <mainClass>com.test.MainClassName</mainClass>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
      <executions>
        <execution>
          <id>make-assembly</id> 
          <phase>package</phase> <!-- packaging phase -->
          <goals>
            <goal>single</goal>
          </goals>
        </execution>
      </executions>
    </plugin>

Answer 2

当我尝试使用Netbeans 12.0 OpenJDK 15时，我需要导入一些我使用OracleJDK 8u231开发的库项目（.jar）进行一些代码测试。结果与问题类似：

 Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.6:single (make-assembly) 
on project rgbfw-as-core-db: Execution make-assembly of goal org.apache.maven.plugins:maven-assembly-plugin:2.6:single 
failed: An API incompatibility was encountered while executing 
org.apache.maven.plugins:maven-assembly-plugin:2.6:single: java.lang.ExceptionInInitializerError: null

对我来说，解决方案是在重新运行Netbeans的“清理并构建”之前，更新我的库项目（.jar）上的“ maven-compiler-plugin”和“ maven-assembly-plugin”版本。项目资源管理器。当前版本：

maven-compiler-plugin（3.8.1）

maven-assembly-plugin（3.3.0）

Maven构建错误 - 无法执行目标org.apache.maven.plugins：maven-assembly-plugin：2.5.5
