Question

我一直在尝试使用maven构建代码。但我遇到了一个错误。这个代码可以在这个github repo上找到。 google-play-crawler

maven所示的系统配置如下：

Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 19:21:28+0530)
Maven home: /Users/tushar/Downloads/apache-maven-3.0.5
Java version: 1.6.0_65, vendor: Apple Inc.

Default locale: en_US, platform encoding: MacRoman
OS name: "mac os x", version: "10.9", arch: "x86_64", family: "mac"

以下是错误的Maven跟踪：

Answer 1

您的Maven正在阅读Java版本1.6.0_65，其中pom.xml表示该版本为1.7。

尝试安装所需的版本。

如果已安装，请检查$ JAVA_HOME环境变量，它应该包含Java JDK 7的路径。如果找不到它，请修复环境变量。

也删除行

 <fork>true</fork>
     <executable>${JAVA_1_7_HOME}/bin/javac</executable>

来自pom.xml

的

Answer 2

对于我的情况，我改变了＆＃34; fork＆＃34;的值。为假，例如<fork>false</fork>。我不明白为什么，希望有人能向我解释。提前谢谢。

Answer 3

我遇到了类似的错误，最终发现清理build文件夹解决了我的问题。

mvn clean install

Answer 4

我有同样的问题。比较时，pom.xml文件中提到的java版本不同， JAVA_HOME env变量指向不同版本的 jdk 。

将 JAVA_HOME 和pom.xml更新为相同的 jdk 安装路径

Answer 5

如果安装了JDK但仍无法正常工作。

在Eclipse中按照以下步骤操作： - 窗口 - ＆gt;偏好 - ＆gt;已安装的JRE - ＆gt;将JRE的路径更改为JDK（添加）。

Answer 6

对我来说，我改变了 C：\ apps \ Java \ jdk1.8_162 \ bin \ javac.exe至 C：\ apps \ Java \ jdk1.8_162 \ bin \ javacpl.exe 由于bin文件夹中没有具有该名称的可执行文件。可行。

Answer 7

对我来说这个技巧有效

我必须从任务管理器中结束 java 任务，因为它无法清理。

重新构建它，它起作用了。

注意：我使用的是windows系统。

无法使用带有错误的MAVEN构建 - 无法执行目标org.apache.maven.plugins：maven-compiler-plugin：3.1：compile
