maven-assembly-plugin给出java堆空间错误

Question

[15:32:58][com.****:project] [INFO] --- maven-assembly-plugin:2.4:single (make-assembly) @ project ---
[15:33:01][com.****:project] [INFO] Reading assembly descriptor: assembly.xml
[16:20:02][com.****:project] [ERROR] Java heap space -> [Help 1]

已尝试将MAVEN_OPTS设置为：

MAVEN_OPTS = -Xms256m -Xmx1024m
MAVEN_OPTS = -Xms512m -Xmx2048m

有什么线索可以解决吗？

Answer 1

问题是关于UNIX上maven-assembly-plugin的配置。

[09:21:17][com.***:project] [DEBUG] FileSet[lib/] dir perms: -1 file perms: -1 lineEndings: unix
[09:21:17][com.***:project] [DEBUG] The archive base directory is 'null'

未在pom.xml配置上设置存档基目录。因此，在Unix上，assembly将存档/lib文件夹，而不是/projects/project/lib。因此，内存不足错误。

这是添加到当前配置的线路：

<archiveBaseDirectory>${project.basedir}</archiveBaseDirectory>

这是最终的配置：

  <plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.4</version>
    <executions>
      <execution>
        <id>make-assembly</id>
        <phase>package</phase>
        <goals>
          <goal>single</goal>
        </goals>
        <configuration>
          <finalName>project</finalName>
          <appendAssemblyId>false</appendAssemblyId>
          <archiveBaseDirectory>${project.basedir}</archiveBaseDirectory>
          <descriptors>
            <descriptor>assembly.xml</descriptor>
          </descriptors>
        </configuration>
      </execution>
    </executions>
  </plugin>
