maven eclipse 工程缺少build path怎么办

Answer 1

缺少build path是因为工程的两个配置文件：.project .classpath没有内容或者缺失。
解决办法：
以一个maven管理的java项目为例。
用下面内容替换掉.project文件

Xml代码

<?xmlversion="1.0"encoding="UTF-8"?>

<projectDescription>

<name>fastjson_source</name>

<comment></comment>

<projects>

</projects>

<buildSpec>

<buildCommand>

<name>org.eclipse.jdt.core.javabuilder</name>

<arguments>

</arguments>

</buildCommand>

<buildCommand>

<name>org.maven.ide.eclipse.maven2Builder</name>

<arguments>

</arguments>

</buildCommand>

</buildSpec>

<natures>

<nature>org.eclipse.jdt.core.javanature</nature>

<nature>org.maven.ide.eclipse.maven2Nature</nature>

</natures>

</projectDescription>

.classpath 文件

Xml代码

<?xmlversion="1.0"encoding="UTF-8"?>

<classpath>

<classpathentrykind="src"output="target/classes"path="src/main/java"/>

<classpathentryexcluding="**"kind="src"output="target/classes"path="src/main/resources"/>

<classpathentrykind="src"output="target/test-classes"path="src/test/java"/>

<classpathentryexcluding="**"kind="src"output="target/test-classes"path="src/test/resources"/>
